Tissue specific drought stress response in different varieties of mungbean (Vigna radiata L wilczek) of Rajasthan

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.

Mungbean (Vigna radiate) adapt to different level of drought stress via production of various biochemicals and antioxidants.

A measure of these antioxidants in six different variety of Mungbean (Vigna radiate), gives idea of drought sensitive and tolerant variety tested

Tissue (leaves and root) were compared for the production of biochemicals and antioxidants, and it was found that leaves were able to produce more biochemicals and antioxidants as compared to roots.
