Abstract

Zinc as an important element plays certain structural and functional roles in the metabolic processes of plants. However, high concentrations of Zn, specially in soils with low pH, is a limiting factor for growth. In this article, the effects of different concentrations of ZnSO4 (0, 25, 50, 75, 150, 250, 350, 450 and 550µM) on certain physiological parameters in Bean (Phaseolus vulgaris L). plants were studied. The results showed that Zn treatments (above 75µM) caused significant decrease in fresh and dry weight, length of root and shoot, soluble sugar content and increase in starch content. Increasing Zn concentration, gradually decreased the content of various photosynthetic pigments, including chlorophylls a, B and CAROTENOIDS. This indicates that chl a is more affected than chl B. The following phytotoxic symptoms were also observed as decreases in GROWTH PARAMETERS. Zn, in low concentrations, caused significant increase of growth in PHASEOLUS VULGARIS, however, high concentrations of Zn affected on physiological and Biochemical processes and decreased growth and production in treated plants.
