Abstract:
Abiotic stresses such as extreme temperatures, low water availability, high salt levels, mineral deficiency and toxicity are frequently encountered by plants. These environmental stress factors negatively affect growth and productivity, and plants have evolved different mechanisms to respond to such challenges. For their survival under the stress conditions, plants respond by different molecular, cellular, biochemical and physical responses. These response mechanisms help plants to survive during the stress period as well as to recover after the stress period. Therefore, aim of the present study is to evaluate the various biochemical characteristic of six varieties of Vigna radiata (RMG-62, RMG-975, MUM-2, MSJ-118, RMG-492 and RMG-344) under different drought stress. Plants are exposed to different levels of drought stress by withdrawing water and parameters like leaf relative water content (RWC), proline content, total chlorophyll content, malondialdehyde (MDA) content & different antioxidant effect (Ascorbate peroxidase, Catalase, Guaiacol peroxidase & Superoxide dismutase ) were measured. Therefore, present study proves that, general growth, physiological and biochemical traits can be used successfully as a way to screen different sensitive and tolerant varieties of Mung bean in drought stress condition.
