Abstract:
The present paper deals with the effect of exogenous application of proline as a shotgun approach on growth, photosynthesis, and antioxidative system in 25-day-old plants of two different cultivars of Brassica juncea L. (Varuna and RH-30) under natural conditions. Exogenous application of proline significantly increased plant growth, photosynthetic rate, and the activities of antioxidant enzymes, compared with untreated seedlings. Pre-sowing seed soaking in 20 mM proline, for 8 h, proved best among all the other concentrations used.
