Abstract
The influence of a wide range of Zn concentrations (0 to 100 M) on the growth and Zn accumulation by soybean (Glycine max(L.) Merr, ov A msoy) was studied under controlled ecological conditions. [At Zn levels below 0-5M-the dry weight of soybean tops and roots was reduced due to Zn deficiency. At higher Zn concentrations (>50 µM) the growth of tops as well as that of roots was also markedly reduced due to Zn toxicity but maximum growth of soybean plants was recorded in the range of 1-5 AM. The lower critical Zn level at which Zn is required at a minimum concentration for maximum growth was 21µg/g in tops, The upper critical Zn level at which inaximum Zn concentration in tops that can be tolerated for maximum growth was 502 la.
