Seasonal Patterns of Nitrate Reductase and Nitrogenase Activities in Phaseolus vulgaris L.

Abstract

The patterns of nitrate reductase activity (NRA) in the leaves (in vivo assay) and root nodule nitrogenase activity (C(2)H(2) reduction) were investigated throughout the season in field-grown Phaseolus vulgaris plants.Maximal NRA (per g fresh weight) occurred at early stages of leaf development but total activity (per leaf) was maximal when the leaf reached… (More)
