Abstract
Response of corchorus capsularis L.
seedlings to various concentration
of nitrate were evaluated in terms of variation in nitrate reductase
activity , total nitrogen , fresh weight, dry weight and leaf size. An increased activity of nitrate
reductase was observed upto 13 days of seedling growth.maximum activity was found in leaves whereas stem exhibited no significant effect of nitrate concentration on enzyme level at different stages of growth . an appreciable increase in total nitrogen by exogenous supply of nitrate was also encounterd where as in nitrogen starved seedlings it declined after 13 days .fresh and dry weight of seedlings were less affected with increasing concentration of nitrate . leaf size increased when seedlings were
