摘要

Green gram (Vigna radiata L.) Wilczek, chiefly grown as a post rainy season crop, faces water stress situation. A complex response, in terms of biochemical and molecular level is shown by plants, when exposed to drought, and depending on that, plants show differential adaptation and tolerance mechanisms. In the studied biochemical parameters, proline, catalase and peroxidase showed increased activity due to water stress and negatively correlated with seed yield and correlation was significant for catalase and peroxidase, while the total chlorophyll content decreased due to water stress and it was positively and significantly correlated with the seed yield. All the biochemical parameters recorded higher values in genotype WGG 37, whereas, lowest total chlorophyll and leaf proline were recorded in MGG 348 and lowest catalase and peroxidase activity in MGG 347. Highest seed yield was recorded by the genotype WGG 37 (1058.71 kg ha~(-1)), followed by WGG 42 (1052.22 kg ha~(-1)), while the lowest seed yield was recorded in MGG 348 (951.42 kg ha~(-1)). Thus indicating the role of the biochemical parameters and total chlorophyll content in stress mitigation.
