Abstract
Combinations of different concentrations of substrate (0.025M, 0.05M, 0.1M, 0.15M, 0.20M and 0.25M KNO3) with different pH of buffer (0.1M, KH2PO4 of the pH 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.5, 7.6, 7.7, 7.8) solutions were tried for the nitrate reductase activity of Erythrina blakei leaves. Maximum nitrate reductase activity was observed in the combination of buffer solution of 0.1M having pH 6.8 and substrate solution of the concentration 0.15M. NR activity and moisture content in single leaf blades of Erythrina blakei leaves of different branches from different levels of tree have different concentration of activity and Moisture percentage. In single leaf blades maximum NR activity was recorded in leaf number 10, Branch number 3. And maximum moisture percentage observed in leaf number 12, Branch number 3.
