Abstract

Growth and ionic relations of red kidney bean plants were compared when grown in 25, 50 and 75 mM concentrations of either NaCl or KCl salts. Similar growth reductions of plants at 25 mM concentration of the two solutions were observed as compared with control solution grown plants. Whereas relatively higher growth reductions indicated by reduced relative growth rates in 50 and 75 mM KC1 solution as compared with isosmotic NaCl solutions were associated with higher Cl and K uptake and accumulation in leaves. This was confirmed by higher short‐term 36Cl uptake/transport in plant leaves from the labelled solution of 50 mM KCl as compared with that from 50 mM NaCl solution.
