Poplar clone Kranti was selected to assess the morphological, physiological and biochemical responses under drought at different levels of water stress, as it is a common clone used to be grown in Uttarakhand for making paper and plywood. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological and biochemical parameters related with drought tolerance were recorded. Alterations in physiological (i.e. decrease in relative water content) and biochemical parameters (i.e. increase in proline and soluble sugar content and build-up of malondialdehyde by-products) occurred in all the three levels of water stress, although drought represented the major determinant. Drought treatments (75%, 50% and 25% FC) decreased plant height, radial stem diameter, harvest index, total biomass content and RWC in all the three watering regimes compared to control (100% FC). Biochemical parameters like proline, soluble sugar and MDA content increased with severity and duration of stress, which helped plants to survive under severe stress. It was analyzed that for better wood yield poplar seedlings should avail either optimum amount of water (amount nearly equal to field capacity of soil) or maximum withdrawal up to 75% of field capacity up to seedling establishment period (60 days). Furthermore, this study manifested that acclimation to drought stress is related with the rapidity, severity, and duration of the drought event of the poplar species.

Drought stress greatly affects the quality and yield of mulberry leaves, which eventually influences the production of silkworm cocoon. In this study, the effect of calcium chloride on drought tolerance of mulberry was investigated. Different concentrations of CaCl2 solutions were sprayed on the leaves of mulberry under drought condition, and the physiological and biochemical responses were measured. As a result, the spray of CaCl2 on leaves (CaCl2-spray-on-leaves) was proved to have gradual increases in measure parameters as compared to CaCl2-untreated case under the same drought condition; furthermore, 20mM CaCl2-treated group showed a significant increase (P<0.05), which indicates the optimal CaCl2 concentration for improving the drought tolerance of mulberry. This study demonstrated that CaCl2-spray-on-leaves can be an effective measure to ameliorate the drought tolerance of mulberry in the severe-drought areas.
