Effect of Chloride on Nitrate Accumulation in Pawpaw (Carica papaya L.)

Abstract

An accumulation of chloride in leaves and fruits of the papaw is associated with high levels of nitrate in these tissues. High chloride levels in tissues did not affect plant growth, protein synthesis or the level of endogenous nitrate reductase acitvity. The amount of nitrate in the non-metabolic pool of leaves and fruits was significantly increased in the presence of chloride.
