In vivo leaf blade and petiole nitrate reductase activity and nitrate content of selected vegetables during vegetative growth



In vivo leaf blade and petiole nitrate reductase activity and nitrate content of selected vegetables during vegetative growth



Journal of the Agricultural Association of China (155): 40-45



Petioles of plants are not generally considered to be major sites of nitrate reductase activity (NRA). Studies were conducted to determine the significance of petiole NRA from 44 greenhouse-grown vegetables from 10 families and 23 genera. An in vivo assay with endogenous nitrate-N only was used to compare petiole NRA and leaf blade NRA. In addition, nitrate-N content of the plant materials was determined. Results indicated substantial petiole in vivo NRA in most species/cultivars when plants were grown vegetatively, and that 14 species/cultivars had rates either similar to or higher than leaf blades. Petiole NRA may contribute substantialy to plant N metabolism in some species.
