EFFECT OF PEG-INDUCED DROUGHT STRESS ON MUNGBEAN PLANTS REVEALED RESISTANT VARIETIES BASED ON LEAF WILTING INDEX AND BIOCHEMICAL MOLECULES

At the early vegetative growth stage, mungbean are mostly affected by drought, and it is also one of most promising stages that can be used to screen for drought stress tolerance traits in multiple varieties. Therefore, this study utilized polyethylene glycol (PEG-6000) induce towards selection varieties their stage using both hydroponics soil based systems. In study, leaf wilting index responses biochemical molecules were as basic factors determine effect PEG-induced among Prior imposition stress, germination potentials evaluated all had = 60%. Except Tvr29 Tvr44, hydroponic system revealed 80% 1 leaves significantly (P 0.05) wilted. The highest LWI recorded Tvr49 Tvr79. Re-evaluation Tvr29, Tvr79 soil, shows TVr44 resisted stress. hydrogen peroxide, superoxide radical malondialdehyde contents decreased TVr29 increased comparison control. Tvr44 high proline content than Based on molecules, should where water deficit a challenge globally.
