The effect of benzyladenine (BA) and ascorbic acid (AA) on relative water content, proline accumulation, net photosynthetic rate (PN), 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 PN, Chl content and NR activity, and ameliorate the negative effect of water stress.

Keywords: chlorophyll content; nitrate reductase activity; photosynthetic rate; proline content; relative water content; senna
Subjects: ascorbic acid, alleviation of water stress; Cassia angustifolia; chlorophylls, water stress, rehydration; cytokinins; gas exchange, phytohormones; gas exchange, water stress, rehydration; nitrate assimilation and metabolism, phytohormones; proline, water stress, phytohormones; rehydration after water stress; relative water content, water stress; senna; water stress, amelioration of negative effects
