Abstract
Bush bean plants (Phaseolus vulgaris L.) were grown in solution culture with factorial combinations of Zn and Mn. Increasing Zn slightly (to 10−4M) decreased vegetative yields of trifoliate leaves of Mn-deficient bush beans, but the differences were not statistically significant. Yields of plants were depressed more than 50% when trifoliate leaves contained 5 or less mg kg−1 dry weight of Mn, about 25% when leaves contained 7 mg kg−1, and about 15% when leaves contained 16 mg kg−1. Chlorotic symptoms were on leaves for the lowest levels of Mn only. The highest level of Zn increased Mn in leaves at the high level of Mn. The low levels of Mn were associated with increased Fe in trifoliate leaves. High Zn increased P and decreased Sr and Mg in trifoliate leaves. It decreased Sr, Ca, Ba, and Mg in some other plant parts, but its effect on Sr was pronounced in all plant parts.
