Abstract
Considering the adverse effect of drought on plants growth, development and physiology, we studied the protective role of three osmolytes, proline (Pro), glycine betaine (GB) and trehalose (Tre) for the mitigation the adversity of drought on rapeseed (Brassica rapa L. cv. BARI Sharisha-15) seedlings. The experiment consisted of eight treatments viz. control, Pro (0.5 mM), GB (0.5 mM), Tre (0.5 mM), Drought (20% Polyethylene glycol, D), Pro + D, GB + D and Tre + D. Reduced plant height, seedling fresh and dry biomass, relative water content (RWC) of leaf and chlorophyll (chl) contents were observed due to drought stress with increased levels of endogenous Pro, GB, and Tre. Drought stress also induced oxidative stress, manifested by the overgeneration of…
