ABSTRACT
In spite of the various biotic and abiotic stresses in the crop field, water deficit condition is a serious challenging situation for crops across the globe which adversely affects the development, growth and production yield of the plants. In the present study, one week old seedling of mung bean (Vigna radiata L.) kept in pot culture was subjected to drought stress. The test plants were then sampled on the 2nd, 4th, 6th and 8th day along with the control plants. Var ious physiological and biochemical parameters were analysed on the test plants along with the well-watered control treatment. Relative water content is seen to decrease during the period of treatment to drought stress. Chlorophyll contents in the leaves of mung bean was seen to decrease in the stressed plants when compared to the control. On the other hand, the proline contents showed an increase during the drought stress in both the leaves and the roots of the test plant. But the sugar contents showed a slightly different trend during the treatment days, where the sugar contents decreased on the 4th day of drought stress but again there was a slight increase on the 6th and 8th day of the treatments.
