Tartaric acid is synthesized on light in the leaves ofTamarindus indica L. and is translocated to the flowers during flowering seasons. The translocation of this acid to fruits keeps peace with their growth rate. The decline of the tartaric acid content per unit fresh weight in mature fruits is not due to their utilization or conversion, but largely due to the setting up of the seeds which are devoid of any tartaric acid. Tartaric acid content in both the leaves and fruits show variation in different seasons, while malic acid does not show any change excepting a small increase in March. 相似文献

Foraging behaviour of Scymnus coccivora Ayyar against cotton mealybug Phenacoccus solenopsis Tinsley

Predation is one of the significant biotic mortality factors reducing the insect pest population as functional response and the numerical response of the predator are the key factor regulating the population dynamics of predator prey species. This study is aimed to evaluate the functional response of all the developmental stages of Scymnus coccivora Ayyar (Coleoptera: Coccinellidae) against the different densities of cotton mealybug, Phenacoccus solenopsis (Tinsley) (Hemiptera: Pseudococcidae) and the numerical response of female predator. Experiments were carried out in controlled environment laboratory conditions at 25 ± 1 °C temperature, 60 ± 5% relative humidity and photoperiod of 16 h. Number of eggs consumed, number of eggs laid and the Efficiency of Conversion of Ingested food (ECI) were recorded daily. Results from the study revealed that all the developmental stages of S. coccivora exhibited a Type II response. Different parameters such as attack rate (a’), handling time (Th) and the maximum rate of predation were estimated using Roger’s random attack equation and Holling Disc equation in which Rogers random attack equation was found best fit. Female has shown the highest attack rate (a’) followed by IVth instar grub, male, IIIrd, IInd and Ist instar grub. With low handling time, IVth instar grub has shown maximum predation rate of 76.40 per day followed by female (75.86), male (58.79), IIIrd (22.84), IInd (19.65) and Ist instar grub (15.39). The numerical response increase was curvilinearly related to different prey densities with the highest number of eggs (11.8 ± 3.44) produced at highest prey density (160). The Efficiency of Conversion of Ingested food (ECI) was highest (64.49 ± 8.03) at prey density of 10. Understanding the factors that lead to variation in functional response of predator in natural population will advance our understanding of the effects of predation on individual and the effectiveness of coccinellid predators as biocontrol agent against cotton mealybug. 相似文献

The purification of estrogen- and progesterone-binding proteins of human uterus by employing affinity resins coupled with
steroid-bovine serum albumin conjugates, led to the isolation of preparations with estrogen- and progesterone-binding sites
havingK
d values in the range of 0.96 to 1.20 × 10-9 M. These were different from theK
d values of 10-10 M and 10-8 M obtained for two types of binding sites present in the crude cytosolic and nuclear fractions. The purified proteins sedimented
on sucrose gradient withS values in the range of 3.6–4.4.
The cytosolic and nuclear estrogen- and progesterone-binding proteins, thus purified, showed differences in specificity of
binding to the hormone. While the cytoplasmic proteins were more specific in their binding to estradiol or progesterone, the
nuclear proteins bound Cortisol with equal or moderate affnity. These results demonstrate the presence of distinct physiological
forms of estrogen- and progesterone-binding proteins in the cytoplasm and nucleus, thus pointing to the importance of both
these compartments in hormone action. 相似文献

Forty‐seven genotypes and one wild relative of soybean, Glycine soja, were screened for resistance against aerial blight under epiphytotic conditions in the field during the Kharif season of two consecutive years viz., 2016 and 2017. Out of the 48 genotypes screened, only 18 genotypes exhibited a moderately resistant response to aerial blight during both the years of study. In order to perform molecular screening of the genotypes for aerial blight resistance, the genomic DNA obtained from the seedlings of the forty‐eight soybean genotypes was subjected to PCR amplification with 12 SSR markers. The SSR markers Satt 119, Sat_076, Satt 433, Satt 281, Satt 277, Satt 245 and Satt 520 were able to clearly amplify different banding pattern for resistant and susceptible genotypes, out of which Satt 433 and Satt 520 were found to exhibit a pattern, highly similar to the results of field screening of the genotypes with respect to resistant and susceptible reaction to the disease. The eighteen soybean genotypes that exhibited moderately resistant reaction to RAB under field conditions during both the years showed a banding pattern similar to resistant check PS‐1583 in the amplification profile produced by the SSR markers. The polymorphism information content (PIC) from the analysis of amplification profile of the SSR markers used in the study, ranged from 0.58 to 0.95. The dendrogram constructed using UPGMA cluster analysis clearly differentiated the resistant and susceptible genotypes of soybean into two separate groups. 相似文献
