Reduction of nitrate ions by morningglory leaves


, : Reduction of nitrate ions by morningglory leaves. Weed Science 22(1): 23-27

The reduction and assimilation of nitrate ions by 14-day-old morning glory (Ipomoea purpurea) seedlings were studied by monitoring the leaf nitrate, protein, and activity of nitrate reductase. The pH's of the grinding and assay mixtures yielding maximum nitrate reductase activity were 8.8 and 7.5-7.7 respectively. The maximum assay time for a linear reaction rate for nitrate reductase was estimated at 10 minutes. Decay rates of the enzyme preparations indicated a half-life of 30 min.
