The effects of Diazinon 60 EC (organophosphate insecticide, active substance diazinon) on mortality, growth rate, early ontogenetic
rate, and occurrence of malformations was studied in embryos and larvae of tench, Tinca tinca (L.). The exposure of fish to 0, 10, 100, 1,000, and 3,000 μg dm−3 of Diazinon 60 EC was initiated 24 h after fertilization of eggs and concluded 32 days later. At the highest concentration
tested (3,000 μg dm−3), total mortality was observed within the first 15 days of exposure. A concentration of 1,000 μg dm−3 caused high incidence of malformations, decrease in growth rate and ontogenetic development slowed down. A concentration
of 100 μg dm−3 mildly decreased growth rate, but at 10 μg dm−3 no changes compared to the control were observed. Thus, Diazion 60 EC at the concentration of 10 μg dm−3 is not dangerous for the embryos and larvae of tench. 相似文献

Effects of post-harvest application of two plant growth regulators viz., gibberellic acid (GA3) and benzyl adenine (BA) with sucrose in the vase solution on cell membrane stability and vase life of gladiolus were investigated.
The vase solution treatment combinations of GA3 and BA with sucrose significantly increased the membrane stability index and enhanced the vase life as compared to the sucrose
alone treatments or the controls. Vase solution treatment of GA3 (50 mg l−1), followed by BA (50 mg l−1) with sucrose (50 g l−1) significantly increased solution uptake, fresh weight and dry weight of cut spikes. The same treatments also enhanced the
concentration of reducing and non-reducing sugars in gladioli petals 4 days after treatment (DAT). Cut spikes in vase solution
enriched with 50 mg l−1 GA3 + 50 g l−1 sucrose showed higher antioxidative enzyme activities of superoxide dismutase (SOD) and glutathione reductase (GR), lower
lipoxygenase (LOX) activity and lipid peroxidation (measured as TBARS). Petal membrane stability index was also highest in
cut spikes 6 DAT with 50 mg l−1 GA3 + 50 g l−1 sucrose vase solution. Treatment of gladiolus cut spikes with 50 mg l−1 GA3 + 50 g l−1 sucrose vase solution showed two fold increase in vase life and improved flower quality with a higher number of open flower
per spike at any one time. These results suggest that post-harvest application of GA3 (50 mg l−1) with sucrose (50 g l−1) maintains higher spike fresh and dry weight, improves anti-oxidative defence, stabilizes membrane integrity leading to a
delay in petal cell death. 相似文献

Mucor indicus can be used to produce ethanol from a variety of sugars, including pentose’s. An extract of it, produced by autolysis, could
replace yeast extract in culture medium with improved production of ethanol. At 10 g l−1, the extract gave a higher ethanol yield (0.47 g g−1) and productivity (0.71 g l−1 h−1) compared to medium containing yeast extract (yield 0.45 g g−1; productivity 0.67 g l−1 h−1). 相似文献

High temperature strongly hampers the plant growth particularly at early growth stages. In this study, changes in some physiological
and anatomical characteristics and possibility of mitigating the adversities of heat stress by soaking sugarcane nodal buds
in 20 mM proline and glycinebetaine (GB) solutions have been explored. Heat stress reduced the rate of bud sprouting nonetheless
soaking the setts in proline followed by GB was beneficial. In addition, heat stress reduced the bud fresh and dry weights,
generated H2O2, reduced the tissue levels of K+ and Ca2+, while increased the osmolytes synthesis in a time course manner. Heat stress also delayed the emergence and expansion of
new bud leaves, by restricting the number and area of mesophyll cells. It also caused poor and aberrant development and diffused
appearance of mesophyll cells and vascular bundles in the bud leaves. However, soaking of buds in proline and GB solutions
substantially reduced the H2O2 production, improved the accumulation of soluble sugars and protected the developing tissues from heat stress effects; although
proline was more effective than GB. Correlations of various attributes indicated that soaking in GB and proline restricted
the H2O2 generation, improved K+ and Ca2+ contents, and increased the concentrations of free proline, GB and soluble sugars eventually improving the heat tolerance
of buds. Cost-benefit analysis showed that, considering increase in sprouting of buds, soaking in 20 mM solution of both osmoprotectants
is economical. 相似文献

The effect of various hormonal combinations on regeneration of shoots and roots from meristem-derived callus of Crocus sativus L. and activities of antioxidant enzymes have been studied. The most efficient regeneration occurred with 1.0 mg dm−3 1-naphthaleneacetic acid (NAA) + 1.0 mg dm−3 thidiazuron and 1.0 mg dm−3 NAA + 2.0 mg dm−3 kinetin. For sprouting, regenerated shoot were subcultured on Murashige and Skoog medium containing 1.0 mg dm−3 NAA + 1.0 mg dm−3 benzylaminopurine (BAP). Protein content and superoxide dismutase activity decreased in regenerated shoots and roots and
increased in sprouting shoots, while catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO) activities increased during
organogenesis and decreased in sprouting shoots. High CAT and PPO activities were detected in regenerated roots, whereas high
POX activity was observed in regenerated shoot. 相似文献

A novel protocol for plant regeneration from cotyledon explants of eggplant (Solanum melongena) reducing concentration of sucrose was established. The most efficient bud induction medium consisted of Murashige and Skoog
(MS) medium supplemented with 2.0 mg dm−3 zeatin, 0.1 mg dm−3 indoleacetic acid and 10 g dm−3 sucrose. After 15 d, the shoot buds were fragmented and transferred to the shoot elongation MS supplemented with 1.0–2.0
mg dm−3 gibberellic acid and 4.0–8.0 mg dm−3 AgNO3, which promoted shoots elongation. The genetic stability of the regenerated plants was analyzed by flow cytometry, RAPD and
SSR molecular markers. The results indicated that almost no somaclonal variation was detected among the regenerants. 相似文献

The different acid invertase activity (total, soluble, wall-bound and extracellular) in calli induced on explants (cotyledon,
petiole, hypocotyl and leaf) originated from Medicago strasseri seedlings were evaluated. In cultures subjected to 16 h photoperiod, the highest total, soluble and extracellular activities
were found in calli from leaves cultured in medium 12 (MS with 0.01 mg·dm−3 (0.045 μM) of TDZ), elevated amounts of total and wall-bound invertase being found in calli induced on petioles in 12G medium
(MS with 0.01 mg·dm−3 (0.045 μM) TDZ and 3.104 mg·dm−3 glycerol). In cultures maintained in darkness, the activity detected was lower than that observed in cultures under light
conditions. The highest amounts of enzyme was bound in calli cultured on medium 12 (total and extracellular invertase) -leaves-
and medium 12D (MS with 0.001 mg·dm−3 (0.0045 μM) TDZ) (soluble invertase) -using hypocotyls. In general, the different forms of invertase activity studied seem
to appear in greatest amounts in calli induced under light conditions using leaves as explant and TDZ as growth regulator. 相似文献

Guggulsterone, a hypolipidemic natural agent, is produced in resin canals of the plant Commiphora wightii. In this study, the stimulatory effects of growth retardants [ALAR (N,N-dimethylaminosuccinamic acid) and CCC (chlormequat chloride)] and fungal elicitor on guggulsterone accumulation in cell cultures
of C. wightii are reported. CCC at 1 mg l−1 enhanced guggulsterone content (~123 μg l−1) when added on the fifth day after inoculation, while ALAR at 2.5 mg l−1 increased guggulsterone content (~116 μg l−1) when added on the tenth day. In a two-stage fed-batch process, combined treatment with fungal elicitor and growth retardant
caused a significant increase (~353 μg l−1) in guggulsterone content in cell cultures after 17 days of growth. This represents an approximately fivefold increase over
the guggulsterone contents in initial cultures of this plant. 相似文献

A highly efficient protocol for plant regeneration from cotyledonary node of two chickpea (Cicer arietinum L.) cultivars ICCV-10 and Annigeri used phenylacetic acid (PAA). The Murashige and Skoog (MS) medium supplemented with 2.0
mg dm−3 6-benzylaminopurine (BAP) and 1.0 mg dm−3 PAA was used for induction of bud formation. Buds were elongated on MS medium supplemented either with only 0.75 mg dm−3 gibberellic acid (GA3) or 0.2 mg dm−3 GA3 + 0.6 mg dm−3 PAA. The elongated shoots were then transferred onto rooting medium containing 1 mg dm−3 PAA. The frequency of multiple shoot induction and rooting was higher in Annigeri as compared to ICCV-10. The complete plantlets
with well-developed roots were transferred to pots containing sterilized soil and sand in the ratio 3:1 where they survived
(74 %) and set normal seeds. 相似文献

Molasses “B” is a rich co-product of the sugarcane process. It is obtained from the second step of crystallization and is
richer in fermentable sugars (50–65%) than the final molasses, with a lower non-sugar solid content (18–33%); this co-product
also contains good vitamin and mineral levels. The use of molasses “B” for ethanol production could be a good option for the
sugarcane industry when cane sugar prices diminish in the market. In a complex medium like molasses, osmotolerance is a desirable
characteristic for ethanol producing strains. The aim of this work was to evaluate the use of molasses “B” for ethanol production
using Saccharomyces cerevisiae ITV-01 (a wild-type yeast isolated from sugarcane molasses) using different initial sugar concentrations (70–291 g L−1), two inoculum sizes and the addition of nutrients such as yeast extract, urea, and ammonium sulphate to the culture medium.
The results obtained showed that the strain was able to grow at 291 g L−1 total sugars in molasses “B” medium; the addition of nutrients to the culture medium did not produce a statistically significant
difference. This yeast exhibits high osmotolerance in this medium, producing high ethanol yields (0.41 g g−1). The best conditions for ethanol production were 220 g L−1 initial total sugars in molasses “B” medium, pH 5.5, using an inoculum size of 6 × 106 cell mL−1; ethanol production was 85 g L−1, productivity 3.8 g L−1 h−1 with 90% preserved cell viability. 相似文献

In this study, a total of 50 rhizobial isolates were recovered from the root nodules of greengram plants. Of the 50 isolates,
9 bradyrhizobial strains namely, MRM1, MRM2, MRM3, MRM4, MRM5, MRM6, MRM7, MRM8, and MRM9, exhibiting a higher tolerance levels
of 600, 800, 1,200, 1,000, 1,000, 1,600, 1,400, 1,400, and 1,000 μg ml−1, respectively, to triazole fungicide tebuconazole (chromatographically pure) were selected and tested for plant growth-promoting
activities. Generally, the rhizobial strain with maximum fungicide-tolerance ability produced higher amounts of plant growth-promoting
substances. Among the nine bacterial strains, Bradyrhizobium strain MRM6 was preferably selected due to its ability to tolerate tebuconazole maximally (up to 1,600 μg ml−1) on minimal salt agar medium. In addition, the strain MRM6 grew well in minimal salts medium supplemented with 100 (recommended),
200 (two times of the recommended), and 300 μg tebuconazole l−1 (three times of the recommended rate) and synthesized highest amounts of plant growth-promoting substances like indole acetic
acid, siderophores, exopolysaccharides, hydrogen cyanate, and ammonia, both in the absence and presence of 100, 200, and 300 μg l−1 of tebuconazole. Following these properties, the strain MRM6 was used as inoculant and the inoculated greengram plants was
raised in soils treated separately with recommended, two and three times the recommended dose of tebuconazole. Generally,
tebuconazole at recommended and the higher rates decreased biomass, nodulation, nutrient-uptake, and grain yield of uninoculated
greengram plants. Interestingly, Bradyrhizobium sp. (vigna) strain MRM6 when used with any concentration of tebuconazole, significantly increased the measured phyto-chemical-parameters
of greengram plants when compared with those grown in soils treated exclusively (without inoculant) with tebuconazole. This
study inferred that the strain MRM6 of Bradyrhizobium sp. (vigna) was compatible with tebuconazole and may be co-inoculated with this fungicide for enhancing the production of legumes especially
greengram in soils poisoned with fungicides. 相似文献

Yeasts that ferment both hexose and pentose are important for cost-effective ethanol production. We found that the soil yeast
strain NY7122 isolated from a blueberry field in Tsukuba (East Japan) could ferment both hexose and pentose (d-xylose and l-arabinose). NY7122 was closely related to Candida subhashii on the basis of the results of molecular identification using the sequence in the D1/D2 domains of 26S rDNA and 5.8S-internal
transcribed spacer region. NY7122 produced at least 7.40 and 3.86 g l−1 ethanol from 20 g l−1
d-xylose and l-arabinose within 24 h. NY7122 could produce ethanol from pentose and hexose sugars at 37°C. The highest ethanol productivity
of NY7122 was achieved under a low pH condition (pH 3.5). Fermentation of mixed sugars (50 g l−1 glucose, 20 g l−1
d-xylose, and 10 g l−1
l-arabinose) resulted in a maximum ethanol concentration of 27.3 g l−1 for the NY7122 strain versus 25.1 g l−1 for Scheffersomyces stipitis. This is the first study to report that Candida sp. NY7122 from a soil environment could produce ethanol from both d-xylose and l-arabinose. 相似文献

The effects of different growth conditions (ventilated and closed vessels, medium with 0, 15 and 30 g dm−3 sucrose) during proliferation of donor quince (Cydonia oblonga Mill.) shoots (stage I) on net photosynthetic rate and soluble sugars content were evaluated. In order to assess the influence
of these physiological parameters on morphogenesis, leaf explants harvested from donor shoots were induced to form somatic
embryos and adventitious roots under ventilated and closed Petri dishes (stage II). Natural ventilation and low sucrose contents
(0–15 g dm−3) promoted the photosynthetic rate of quince shoots whereas biomass accumulation was the highest in those shoots cultured
with 30 g dm−3 sucrose in both vessel types and 15 g dm−3 sucrose under natural ventilation. Increasing sucrose content in the medium induced greater accumulation of sucrose in leaf
tissues of donor shoots. The content of reducing sugars was higher than that of sucrose, and it appeared to be higher in shoots
cultured under natural ventilation compared to those in closed vessels. Somatic embryogenesis and root regeneration were influenced
by stage I and II treatments. A significant correlation between sucrose content in the leaves of donor shoots and the number
of somatic embryos regenerated was found, suggesting that identification of biochemical and physiological characteristics
of donor shoots associated with increased regeneration ability might be helpful for improving morphogenesis in plant tissue
culture. 相似文献

Banana plantlets (Musa acuminata cv Grande Naine) cultivated in hydroponics take up silicon proportionally to the concentration of Si in the nutrient solution
(0–1.66 mM Si). Here we study the Si status of banana plantlets grown under controlled greenhouse conditions on five soils
developed from andesitic volcanic ash, but differing in weathering stage. The mineralogical composition of soils was inferred
from X-ray diffraction, elemental analysis and selective chemical/mineralogical extractions. With increasing weathering, the
content of weatherable primary minerals decreased. Conversely, clay content increased and stable secondary minerals were increasingly
dominant: gibbsite, Fe oxides, allophane, halloysite and kaolinite. The contents of biogenic Si in plant and soil were governed
by the reserve of weatherable primary minerals. The largest concentrations of biogenic Si in plant (6.9–7 g kg−1) and soil (50–58 g kg−1) occurred in the least weathered soils, where total Si content was above 225 g kg−1. The lowest contents of biogenic Si in plant (2.8–4.3 g kg−1) and soil (8–31 g kg−1) occurred in the most weathered desilicated soils enriched with secondary oxides and clay minerals. Our data imply that soil
weathering stage directly impacted the soil-to-plant transfer of silicon, and thereby the stock of biogenic Si in a soil–plant
system involving a Si-accumulating plant. They further imply that soil type can influence the silicon soil–plant cycle and
its hydrological output. 相似文献

Effect of ethephon on sweet cherry pedicel-fruit retention force and quality is cultivar dependent 总被引:1,自引:0,他引:1
Ethephon (2-chloroethyl phosphonic acid) is effectively used to promote development of the pedicel-fruit abscission zone in
tart cherry (Prunus cerasus) for mechanical harvest. Our research program is investigating the use of ethephon to promote pedicel-fruit retention force
(PFRF) reduction on new sweet cherry (P. avium) cultivars to assist mechanized harvest and its affect upon fresh market quality fruit. Ethephon treatments were made at
different timings and rates to ‘Bing’ and ‘Chelan’ during the 2006 season. Ethephon applications to ‘Bing’ trees more than
10 days prior to harvest were effective at reducing PFRF and facilitating mechanical harvest, irrespective of rate (1.2, 3.5,
5.8 L ha−1 [1, 3, 5 pt A−1]). Ethephon applied fewer than 10 days prior to harvest did not reduce PFRF sufficiently. In contrast, no rate or timing
of ethephon studied induced a reduction in ‘Chelan’ PFRF sufficient for mechanical harvest. Accompanying PFRF analyses, fruit
quality was assessed by measuring firmness (g mm−1), soluble solids (oBrix), weight (g) and color (CTIFL, scale 1–7). Ethephon applied 22 days before harvest at a rate of 3.5 L ha−1 enhanced exocarp color in ‘Bing’ by 27%, while reducing firmness in both ‘Bing’ (−19%, 22 days prior to harvest) and ‘Chelan’
(−15%, 20 days prior to harvest). We observed a significant natural decline in ‘Skeena’ PFRF to levels acceptable for mechanical
harvest. This research documents genotypic-specific pedicel-fruit abscission characteristics and the potential to facilitate
mechanical harvest of fresh market quality sweet cherry fruit using ethephon. 相似文献

Plant and soil carbon accumulation following fire in Mediterranean woodlands in Spain 总被引:1,自引:0,他引:1
We measured plant and soil carbon (C) storage following canopy-replacing wildfires in woodlands of northeastern Spain that
include an understory of shrubs dominated by Quercus coccifera and an overstory of Pinus halepensis trees. Established plant succession models predict rapid shrub recovery in these ecosystems, and we build on this model by
contrasting shrub succession with long-term C storage in soils, trees, and the whole ecosystem. We used chronosequence and
repeated sampling approaches to detect change over time. Aboveground plant C increased from <100 to ~3,000 g C m−2 over 30 years following fire, which is substantially less than the 5,942 ± 487 g C m−2 (mean ±1 standard error) in unburned sites. As expected, shrubs accumulated C rapidly, but the capacity for C storage in
shrubs was <600 g C m−2. Pines were the largest plant C pool in sites >20 years post fire, and accounted for all of the difference in plant C between
older burned sites and unburned sites. In contrast, soil C was initially higher in burned sites (~4,500 g C m−2) than in unburned sites (3,264 ± 261 g C m−2) but burned site C declined to unburned levels within 10 years after fire. Combining these results with prior research suggests
two states for C storage. When pine regeneration is successful, ~9,200 g C m−2 accumulate in woodlands but when tree regeneration fails (due to microclimatic stress or short fire return intervals), ecosystem
C storage of ~4,000 g C m−2 will occur in the resulting shrublands. 相似文献

Prolific differentiation of shoot buds of Leucaena leucocephala was induced from the different plant parts viz. cotyledon, hypocotyl and leaf. Adventitious shoot bud formation was recorded
with prudent application of N6-2- (isopentenyl) adenosine and 15% (v/v) coconut water. Coconut water alone was unable to produce any beneficial effect with
regard to the shoot bud proliferation but the response was augmented with the increase in concentration of N6-2- (isopentenyl) adenosine. However supra-optimal level of N6-2-(isopentenyl) adenosine was inhibitory. Best response was recorded from the cotyledon explant at 2 mg dm−3 N6-2-(isopentenyl) adenosine compared to the other two explants. Comparative assessment was undertaken following the same experimental
protocol in liquid shake culture. The regenerated shoot buds were subcultured in plant growth regulator-free medium where
leafy shoot emergence was recorded. Optimum regeneration of roots was observed in these shoots in presence of 1 mg dm−3 α-naphthalene acetic acid. Plantlets were finally hardened following standard procedures before transplantation to the field.
In another experimental set up, the de-embryonated cotyledons regenerated shoot buds via callus formation. The regenerated
shoots and plantlets obtained through callus mediated organogenesis could be used for rapid multiplication and also for the
genetic improvement of individual clones of Leucaena leucocephala. 相似文献

This study was designed to identify rhizobial strains specific to greengram expressing higher tolerance against insecticides,
fipronil and pyriproxyfen, and synthesizing plant growth regulators even amid insecticide-stress. Of the 50 bradyrhizobial
isolates, the Bradyrhizobium sp. strain MRM6 showed tolerance up to 1,600 μg mL−1 against each of fipronil and pyriproxyfen. The tolerant Bradyrhizobium sp. (vigna) produced plant growth promoting substances in substantial amounts, both in the presence and absence of insecticides. The
strain MRM6 was further used to investigate its impact on greengram grown in soils treated with 200 (the recommended dose),
400 and 600 μg kg−1 soil of fipronil and 1,300 (the recommended dose), 2,600 and 3,900 μg kg−1 soil of pyriproxyfen. Fipronil at 600 μg kg−1 soils and pyriproxyfen at 3,900 μg kg−1 soils had greatest toxic effects and decreased plant biomass, symbiotic efficiency, nutrient uptake and seed yield of greengram
plants. The Bradyrhizobium sp. (vigna) inoculant when used with fipronil and pyriproxyfen significantly increased the measured parameters compared to the plants
grown in soils treated solely with the same concentration of each insecticide. This study inferred that the Bradyrhizobium sp. (vigna) strain MRM6 may be exploited as bio-inoculant to increase the productivity of greengram exposed to insecticide-stressed
soils. 相似文献

An in vitro propagation system was developed for castor-bean (Ricinus communis L. cv. TMV 6) through cotyledon derived callus cultures. The impact of different concentrations of auxins, cytokinins, additives,
amino acids and sugars were evaluated for callus induction and shoot proliferation. Green compact nodular organogenic callus
was obtained on the medium fortified with Murashige and Skoog (MS) salts, B5 vitamins, 2.0 mg dm−3 6-benzyladenine and 0.8 mg dm−3 α-naphthalene acetic acid (NAA). Multiple shoot proliferation from the callus cultures was achieved on the medium with MS
salts, B5 vitamins, 2.5 mg dm−3 thidiazuron (TDZ), 0.4 mg dm−3 NAA and 15 mg dm−3 glutamine. During multiple shoot induction the phenolic secretion was controlled by the addition of 15 mg dm−3 polyvinylpyrolidone. The proliferated shoots were elongated on the medium comprising MS salts, B5 vitamins, 1.5 mg dm−3 TDZ and 0.3 mg dm−3 gibberellic acid. The elongated shoots were rooted on the medium containing MS salts, B5 vitamins, 0.3 mg dm−3 indole-3-butyric acid and 0.6 mg dm−3 silver nitrate. After root induction, the plants were hardened in earthen pots containing sand, soil and vermiculite. 相似文献

A yeast strain Kluyveromyces sp. IIPE453 (MTCC 5314), isolated from soil samples collected from dumping sites of crushed sugarcane bagasse in Sugar Mill,
showed growth and fermentation efficiency at high temperatures ranging from 45°C to 50°C. The yeast strain was able to use
a wide range of substrates, such as glucose, xylose, mannose, galactose, arabinose, sucrose, and cellobiose, either for growth
or fermentation to ethanol. The strain also showed xylitol production from xylose. In batch fermentation, the strain showed
maximum ethanol concentration of 82 ± 0.5 g l−1 (10.4% v/v) on initial glucose concentration of 200 g l−1, and ethanol concentration of 1.75 ± 0.05 g l−1 as well as xylitol concentration of 11.5 ± 0.4 g l−1 on initial xylose concentration of 20 g l−1 at 50°C. The strain was capable of simultaneously using glucose and xylose in a mixture of glucose concentration of 75 g l−1 and xylose concentration of 25 g l−1, achieving maximum ethanol concentration of 38 ± 0.5 g l−1 and xylitol concentration of 14.5 ± 0.2 g l−1 in batch fermentation. High stability of the strain was observed in a continuous fermentation by feeding the mixture of glucose
concentration of 75 g l−1 and xylose concentration of 25 g l−1 by recycling the cells, achieving maximum ethanol concentration of 30.8 ± 6.2 g l−1 and xylitol concentration of 7.35 ± 3.3 g l−1 with ethanol productivity of 3.1 ± 0.6 g l−1 h−1 and xylitol productivity of 0.75 ± 0.35 g l−1 h−1, respectively. 相似文献
