Effect of Meloidogyne incognita on Plant Nutrient Concentration and Its Influence on the Physiology of Beans

Phaseolus vulgaris plants, 3, 8, 11, and 13 days old, were inoculated with 0, 2,000, 4,000, or 8,000 second-stage Meloidogyne incognita larvae and maintained under controlled conditions. The photosynthetic rate and the shoot and root concentration of K, Ca, Mn, Fe, Cu, and Zn were determined by destructive assay at 1-27-day intervals and by nondestructive assay of leaves, stems, and roots at 27 or 28 days after inoculation. In the destructive assay, the concentration of the elements in the plant tissues did not change until 1 week after inoculation. Thereafter, the trend was mostly decreasing for shoot K and Fe and increasing in the root, whereas Ca had the opposite trend in the shoots. Manganese, Cu, and Fe showed variable trends. Generally, the concentration of K and Mn increased, whereas Ca and Fe decreased, with duration of infection in all treatments. Zinc and Cu decreased in the highest nematode treatments. The overall elemental content generally decreased with level of infection from 1 week after inoculation. Photosynthetic rate based on shoot K concentration significantly decreased with level of infection. In most of the nondestructive assays, the concentrations of shoot K, Zn, and Mn decreased, whereas Ca increased with increasing nematode treatment. One of the first effects of the nematode on host physiology appears to be a change in concentration of nutrient elements in the host plant.     

Mineral Elements in Root of Wild Saposhnikovia divaricata and Its Rhizosphere Soil

Mineral elements are important components of medicinal herbs, and their concentrations are affected by many factors. In this study, Ca, Mg, Na, K, Fe, Mn, Cu, and Zn concentrations in wild Saposhnikovia divaricata and its rhizosphere soil collected from seven locations at two different times in China were measured, and influences of rhizosphere soil on those minerals in plant were evaluated. The results showed that mean concentrations of eight minerals in plant samples decreased in the order: Ca > Mg > Na > K > Fe > Zn > Mn > Cu, and those in the soil samples followed the following order: Na > Fe > Ca > K > Mg > Mn > Zn > Cu. Mean concentrations of Ca, Na, Mg, and K in plants were higher than those in soils, while higher mean concentrations of the other four minerals were found in soils. It was found that there was a positive correlation of Mg, Na, and Cu concentrations in the plant with those in the soil respectively, but a negative correlation of Mn concentration in plant with that in the soil. Except Ca, K, and Mn, the other five minerals in plant were all directly affected by one or more chemical compositions of soil. The results also indicate that pH value and concentrations of total nitrogen, Mg, Mn, and Cu in soil had significant correlations with multimineral elements in plant. In a word, mineral elements uptake of S. divaricata can be changed by adjusting the soil fertility levels to meet the need of appropriate quality control of S. divaricata.

Imidacloprid‐induced transference effect on some elements in rice plants and the brown planthopper Nilaparvata lugens (Hemiptera: Delphacidae)

Abstract The widespread use of imidacloprid against insect pests has not only increased the rate of the development of target pest resistance but has also resulted in various negative effects on rice plants and Nilaparvata lugens resurgence. However, the effect of imidacloprid on elements in rice plants and the transference of these element changes between rice and N. lugens are currently poorly understood. The present study investigated changes of Cu, Fe, Mn, Zn, Ca, K, Mg and Na contents in rice plants following imidacloprid foliar sprays in the adult female of N. lugens that develops from nymphs that feed on treated plants and honeydew produced by females. The results indicated that imidacloprid foliar spray significantly increased Fe and K contents in leaf sheaths. Generally, Fe, Mn, K and Na contents in leaf blades were noticeably decreased, but Ca contents in leaf blades for 10 and 30 mg/kg imidacloprid treatments were significantly increased. The contents of most elements except K and Mg in the adult females and honeydew were significantly elevated. Multivariate statistical analysis showed that Fe, Mn and Na in leaf blades and Fe and Mn in leaf sheaths could be proportionally transferred to N. lugens. The relationship between most elements in adult female bodies and in the honeydew showed a positive correlation coefficient. There were significant differences in the contents of some elements in rice plants and N. lugens from different regions.

对全国范围内120个样点660种陆生植物共1781个植物样本的叶片S、K、Na、Fe、Ca、SiO2、Al、Mn含量特征进行了研究。各元素的平均含量大小顺序为KCaSiO2NaSAlFeMn,总体上属于KCa型。与世界陆生植物平均元素含量相比较,我国植物叶片Na的含量偏高。除Ca在草本植物中的含量低于木本植物外,为满足快速生长的需要,S、K、Na、Fe、Ca、SiO2的含量草本植物木本植物、落叶植物常绿植物、阔叶植物针叶植物,而Mn的含量在这些功能组却刚好相反,Al的含量变化不大。S、K、SiO2在针叶林中的含量最低,S、Na、Fe在荒漠植物中的含量最高。Ca与SiO2、Al,以及Mn与除Al之外的其他6种元素之间均呈极显著负相关(P0.01),除此之外,植物元素含量间的相关关系都为极显著正相关(P0.01)。植物叶片元素含量与植物所处的地理位置的相关分析表明,S、K、Na、Fe、Ca、SiO2含量随纬度的增加而增加,Al、Mn随纬度的增加而减少;S、K、Na、Fe、SiO2、Al随经度的增加而减少,Mn随经度的增加而增加,而Ca与经度间相关性不显著。     

Growth of Dalbergia sissoo in desert regions of western India using municipal effluent and the subsequent changes in soil and plant chemistry

Increasing demand for fodder and fuelwood and the scarcity of a good quality water in arid areas has resulted in a search for an alternative source of water for biomass production. An experiment utilizing municipal effluent in growing Dalbergia sissoo was conducted. Five treatments included T1, municipal effluent at 1 PET (Potential evapo-transpiration) (without plant); T2, municipal effluent at 1/2 PET; T3, municipal effluent at 1PET; T4, municipal effluent at 2 PET; and T5, canal water at 1 PET. Observations included plant height, collar diameter at one-month intervals and plant mineral composition, mineral uptake and changes in soil properties at 24 months of plant age. Application of municipal effluent produced better growth in D. sissoo seedlings. Concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were greater in seedlings irrigated with municipal effluent than those of the seedlings irrigated by the treatment T5, and positively related with the quantity of irrigation. The concentrations were greatest in foliage compared to the other parts of seedling, with the exception of Cu concentration. Application of municipal effluents resulted in a 2- to 3-fold increase in the concentrations of soil K, Cu, Fe, Mn and Zn, whereas NH4-N and PO4-P availability increased by 8.1- and 4.5-fold, respectively. The increase in soil organic carbon was only observed in treatments T3 and T4. The accumulations of soil NO3-N, Na, Cu, Fe, Mn and Zn were more in lower soil layers but the other soil parameters showed their greatest values in the upper soil layer. Irrigation using municipal effluent did not result in toxicity to the seedlings before the age of 24 months. The results suggest that municipal effluent could be utilized, as an important source of water and nutrients in growing D. sissoo to increase biomass production in the needs of suburban dwellers. However, a preliminary treatment to reduce excess NH4-N and PO4-P will be required before application to the plantation.     

The Rengen Grassland Experiment: relationship between soil and biomass chemical properties, amount of elements applied, and their uptake

The Rengen Grassland Experiment (RGE) was established in the Eifel Mountains (Germany) on a low productive Nardetum in 1941. Since then, the following fertilizer treatments have been applied with a late two-cut system: unfertilized control, Ca, CaN, CaNP, CaNPKCl and CaNPK₂SO₄. We aimed to understand how concentrations of macro (N, P, K, Ca and Mg), micro (Cu, Fe, Mn and Zn) and trace (As, Cd, Cr, Ni and Pb) elements in the plant biomass were affected by long-term fertilizer application, soil chemical properties and biomass production. In 2008, biomass samples from the first cut (early July) and the second cut (mid-October) were collected and analyzed. The simultaneous application of N, P and K decreased nitrogen concentration in the aboveground biomass, but substantially increased biomass production. Late cutting management decreased forage quality in highly productive more than in low productive plant communities. The concentrations of P and K in the plant biomass were positively related to P and K application and, therefore, to plant available P and K concentrations in the soil. The concentrations of some micro (Fe, Mn and Zn) and trace (As, Cd, Cr, Ni and Pb) elements in the plant biomass were negatively correlated with the amount of elements supplied by fertilizers and biomass production, probably because of the dilution effect. Long-term fertilizer application resulted in the accumulation of macro (P, Ca and Mg), micro (Fe and Mn) and trace (As and Cr) elements in the soil, but in many cases this accumulation was not connected with an increase in the concentrations of these elements in the plant biomass. Nutritional status, as indicated by the biomass N:P ratio, was consistent with N or P limitation as indicated by the nitrogen and phosphorus nutrition indices. Furthermore, additional K (co-)limitation was indicated by the N:K and K:P ratios in the biomass from the NP treatment. The results from the RGE indicate that there is no simple positive relationship between the applied elements and their concentrations in the plant biomass.

森林和沼泽对溪流水化学特征的影响

以小兴安岭北部公别拉河上游为研究区,于2004年7～9月对森林溪流和沼泽溪流水样进行水化学特征对比分析.结果表明,森林和沼泽溪流水化学类型均为重碳酸盐类钙组Ⅰ型水(C^Ca_Ⅰ).森林溪流水的pH、矿化度、总硬度、HCO₃^-、SO₄^2-、Ca²⁺、Mg²⁺、Fe均低于沼泽溪流,而总氮、总磷、Cl^-、K⁺、Na⁺则高于沼泽溪流.森林溪流和沼泽溪流中重金属元素Fe、Mn、Cu、Zn、Cd、Hg和Pb含量较低,均未超过我国Ⅰ类地表水环境质量标准.森林溪流中总氮含量为（0.27±0.04） mg·L^-1、总磷含量为（0.040±0.005） mg·L^-1,明显高于沼泽溪流中总氮含量(（0.21±0.02） mg·L^-1)和总磷含量(（0.025±0.004） mg·L^-1),沼泽湿地对N、P有较强的储存和吸附能力,且对NH₄⁺-N的吸附作用远大于对NO₃^--N的吸附.沼泽溪流中Fe含量为（0.26±0.05） mg·L^-1,显著高于森林溪流Fe含量,沼泽湿地对Fe起到还原释放作用.     

Evaluation of Populus and Salix continuously irrigated with landfill leachate I. Genotype-specific elemental phytoremediation

There is a need for the identification and selection of specific tree genotypes that can sequester elements from contaminated soils, with elevated rates of uptake. We irrigated Populus (DN17, DN182, DN34, NM2, NM6) and Salix (94003, 94012, S287, S566, SX61) genotypes planted in large soil-filled containers with landfill leachate or municipal water and tested for differences in inorganic element concentrations (P, K, Ca, Mg, S, Zn, B, Mn, Fe, Cu, Al, Na, and Cl) in the leaves, stems, and roots. Trees were irrigated with leachate or water during the final 12 wk of the 18-wk study. Genotype-specific uptake existed. For genera, tissue concentrations exhibited four responses. First, Populus had the greatest uptake of P, K, S, Cu, and Cl. Second, Salix exhibited the greatest uptake of Zn, B, Fe, and Al. Third, Salix had greater concentrations of Ca and Mg in leaves, while Populus had greater concentrations in stems and roots. Fourth, Populus had greater concentrations of Mn and Na in leaves and stems, while Salix had greater concentrations in roots. Populus deltoides x P. nigra clones exhibited better overall phytoremediation than the P. nigra x P. maximowiczii genotypes tested. Phytoremediation for S. purpurea clones 94003 and 94012 was generally less than for other Salix genotypes. Overall, concentrations of elements in the leaves, stems, and roots corroborated those in the plant-sciences literature. Uptake was dependent upon the specific genotype for most elements. Our results corroborated the need for further testing and selecting of specific clones for various phytoremediation needs, while providing a baseline for future researchers developing additional studies and resource managers conducting on-site remediation.     

Biomass and chemical composition of fertilized and/or irrigated Pinus resinosa Ait. plantations

Estimates were made of the above-ground biomass and contents of ash, N, P, K, Ca, Mg, Na, Mn, Al, Fe, Zn, and Cu by plant components for a 40-year-old Pinus resinosa Ait. plantation growing on a known K-deficient site and treated with KCl fertilizer and/or irrigation. Regression equations were developed from sample-tree data, obtained by total tree analysis techniques, for each tree component on each treatment. After an examination of analytical techniques, it was determined that the contents of the fertilized trees increased more than 140 per cent K, 70 per cent Mn, and 50 per cent N compared to the nonfertilized trees, while the increases in contents of the other elements were more closely related to the 22 percent increase in the biomass of the fertilized trees. The approximate ratio of contents of elements in the total above-ground biomass, expressing Cu=1, was Ca 1000, N 800, K 260, P 90, Mn 90, Mg 75, Al 50, Na 20, Fe 15, Zn 8, Cu 1. The 75 kg per ha more K in the above-ground biomass of the fertilized trees compared to nonfertilized trees was about 15 per cent of the total K applied in the fertilizer. The influence of irrigation on the biomass and chemical composition of the trees was minimal.     

东北羊草草地锰、铜、锌含量特征的研究

 本文研究了羊草(Aneurolepidium chinense)草地割草场3种植物必需的微量元素锰、铜、锌的含量特征。结果表明,在生长季各时期,优势种羊草各器官元素含量有很大变化,总的趋势是：根>根茎>茎>叶>穗(Zn：叶>茎),各器官之间元素含量差异显著(P<0.05)。其它种类植物根中锰、铜、锌含量也显著高于地上各器官。羊草地上部锰、铜、锌积累量在生长季中的变化近似于“S”型曲线,但各元素曲线最高点出现的时间不同。寸草苔(Carex duriuscula)和针蔺(Heleocharis acicularis)地上部锰、铜、锌积累量变化与生物量变化相似,基本为双峰型曲线。三种元素在群落中的分布规律是：根>茎>叶>穗,与生物量分布规律相同。但锰、铜在地上各器宫中积累量占植物总积累量的比率低于相应的生物量比率,而锌这两者的比率则与生物量比率相近。群落中锰、铜、锌积累量与根层土壤中锰、铜、锌总量之比分别为0.10%,0.33%和0.09%。     

川东红池坝地区红三叶和鸭茅人工草地土壤和植物营养元素含量特征的研究

川东红池坝地区红三叶（Ｔｒｉｆｏｌｉｕｍｐｒａｔｅｎｓｅ）和鸭茅（Ｄａｃｔｙｌｉｓｇｌｏｍｅｒａｔａ）人工草地土壤和植物营养元素的含量特征如下：（１）土壤中的元素含量以铁、钾和镁较高,钠、钙、氮、锰和磷较低,硫、锌、硼、铜和钼微少;（２）从元素的富集特征来看,该区土壤中的钙、硫为重度淋溶元素,钾、磷、镁、锌、钠为中度淋溶元素,铁、铜属轻度淋溶元素,锰属富集元素;（３）根据元素的生物吸收系列,红三叶属氮－钙型植物,鸭茅属氮－钾－磷型植物。（４）两种牧草的生物吸收系数,均以钙、硫、磷较高,钠、铁较低,其余７种元素介于二者之间。     

The effects of copper, manganese and zinc on plant growth and elemental accumulation in the manganese-hyperaccumulator Phytolacca americana

Synchrotron radiation X-ray fluorescence (SRXRF) and inductively coupled plasma mass spectrometry were used to estimate major, minor and trace elements in Cu-, Zn- and Mn-treated Phytolacca americana. The effects of the addition of Cu, Zn and Mn on morphological parameters, such as root length, shoot height, and fresh and dry weights of shoots and roots, were also examined. In addition, the activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), guaiacol peroxidases (GPX) and catalase (CAT) and the expression of Fe-SOD, Cu/Zn-SOD, metallothionein-2 and glutathione S-transferase (GST) exposed to the highest amounts of Cu, Zn or Mn were detected. Our results confirmed the following: (1) Zn supplementation leads to chlorosis, disturbed elemental homeostasis and decreased concentrations of micro- and macroelements such as Fe, Mg, Mn, Ca and K. Cu competed with Fe, Mn and Zn uptake in plants supplemented with 25μM Cu. However, no antagonistic interactions took place between Cu, Zn, Mn and Fe uptake in plants supplemented with 100μM Cu. Mn supplementation at various concentrations had no negative effects on elemental deficits. Mn was co-located with high concentrations of Fe and Zn in mature leaves and the concentrations of macro elements were unchanged. (2) P. americana supplemented with increased concentrations of Zn and Cu exhibited lower biomass production and reduced plant growth. (3) When plants were supplemented with the highest Zn and Cu concentrations, symptoms of toxicity corresponded to decreased SOD or CAT activities and increased APX and GPX activities. However, Mn tolerance corresponded to increased SOD and CAT activities and decreased POD and APX activities. Our study revealed that heavy metals partially exert toxicity by disturbing the nutrient balance and modifying enzyme activities that induce damage in plants. However, P. americana has evolved hyper accumulating mechanisms to maintain elemental balance and redox homeostasis under excess Mn.     

Elemental composition of native wetland plants in constructed mesocosm treatment wetlands

Plants that accumulate a small percentage of metals in constructed treatment wetlands can contribute to remediation of acidic, metal contaminated runoff waters from coal mines or processing areas. We examined root and shoot concentrations of elements in four perennial wetland species over two seasons in mesocosm wetland systems designed to remediate water from a coal pile runoff basin. Deep wetlands in each system contained Myriophyllum aquaticum and Nymphaea odorata; shallow wetlands contained Juncus effusus and Pontederia cordata. Shoot elemental concentrations differed between plants of deep and shallow wetlands, with higher Zn, Al, and Fe concentrations in plants in shallow wetlands and higher Na, Mn, and P concentrations in plants in deep wetlands. Root and shoot concentrations of most elements differed between species in each wetland type. Over two seasons, these four common wetland plants did help remediate acidic, metal-contaminated runoff from a coal storage pile.     

Impact of groundnut rosette disease on nutritive value and elemental composition of four varieties of peanut (Arachis hypogaea)

Proximate and elemental composition of four peanut genotypes infected with groundnut rosette disease (GRD) was examined. Moisture and ash content generally decreased while fat and energy content increased in seeds from diseased plants. Protein and carbohydrate varied between seeds of diseased and healthy plants of the different varieties with no consistent pattern. Instrumental neutron activation analysis of 10 elements within leaves, stems and seeds showed elevated levels of K, Al and Cl in leaves, stems and seeds in at least three of the four varieties infected with GRD while Na was decreased in stems but increased in seeds. While significant differences were found, Mg, Mn, Ca and Zn did not show any consistent change with respect to plant part or genotype, between diseased and healthy plants. V and Fe were found at low levels in leaves and stems and not detected in seeds. This represents the first report on the effect of GRD on the nutritive quality of peanuts.     

Content and health risk assessment of selected elements in commercially available fish and fish products

Selected elements (Na, K, P, Mg, Fe, Zn, Cr, Ni, Cu, Mn, Pb, Hg) in fish and fish products bought in supermarkets in Krakow were investigated. Contents of elements were analyzed using AMA 254 apparatus for Hg, and ICP-AES method on JY238 ULTRACE apparatus after samples digestion (HNO₃+HClO₄ 3:1) for other elements. Elements’ concentrations in six fish species and fish products were within the range of (mg/kg w.m.): 2151–6239 for Na; 855–2500 for K; 49.3–183 for P; 353–531 for Mg; 32.6–61.3 for Fe; 4.01–17.6 for Zn; 7.04–12.9 for Cr; 4.25–7.98 for Ni; 1.30–2.27 for Cu; 0.99–1.51 for Mn; 0.09–0.21 for Pb; and 0.01–0.13 for Hg. Human health risk assessment revealed that total non-carcinogenic risk was low to medium with general decreasing order: tuna > salmon > herring> pollock > crab sticks > iridescent shark-catfish. The carcinogenic risk was acceptable for adults and unacceptable for children. Carcinogenic risk values for all subpopulations for Pb were decreasingly ordered as follows: tuna > salmon > herring > pollock > iridescent shark-catfish > crab sticks; and for Cr(VI): tuna > salmon > herring > pollock > crab sticks > iridescent shark-catfish.
