Amelioration of negative effect of water stress in Cassia angustifolia by benzyladenine and/or ascorbic acid

The effect of benzyladenine (BA) and ascorbic acid (AA) on relative water content, proline accumulation, net photosynthetic rate (P-N), chlorophyll (Chl) content and nitrate reductase (NR) activity, under sufficient water supply and moisture stress was studied in senna (Cassia angustifolia Vahl:) at seedling, vegetative, flowering and pod formation stages. AA treatment resulted in a higher accumulation of proline at all the stages of growth. Both BA and AA enhanced P-N, Chi content and NR activity, and ameliorate the negative effect of water stress.
