ABSTRACT
An experiment was carried out at College of Horticulture, Rajendranagar, Hyderabad summer, 2023 to study the variability, heritability and genetic advance for different morphological and agronomic traits. Analysis of variance revealed significant variability among the genotypes of okra for all character’s studied. Genetic variability revealed that a lot of variation among the genotypes. In general, the lowest difference in phenotypic and genotypic coefficients of variation indicated lowest environmental influence in controlling the expression of the traits. Based on genetic variability studies, high PCV and GCV and high heritability coupled with high genetic advance as per cent of mean were recorded for number of branches per plant at 60 DAS, number of branches per plant at 90 DAS, fruit yield per plant and yield per hectare indicating the existence of wider genetic variability for these traits in the germplasm under study.
ABSTRACT
Pyranine entrapped soylipid liposomes have been used as a model system to study the proton transport across membrane in the presence of A23187, a carboxylic ionophore specific for electroneutral exchange of divalent cations. An apparent rate constant (kapp) for transport of protons has been determined from the rate of change of fluorescence intensity of pyranine by stopped flow rapid kinetics in the presence of proton gradient The variation of kapp has been studied as a function of ionophore concentration and the results have been compared with gramicidin—a well known channel former under the similar experimental conditions. The rates thus obtained showed that A23187 is not only a simple carrier but also shows channel behaviour at high concentration of ionophore.
