Abstract
Germination and growth of seeds of Cicer arietinum L. are retarded or inhibited either by temperatures above 30°C or by the presence of abscisic acid (ABA). Both treatments affect the uptake of K+ and glucose. ABA may affect the properties of the cell membrane or the kinetics of the enzymes bound to it. Fusicoccin (FC) and thiourea (TU) are to a greater or lesser extent able to counteract the inhibition produced by ABA and high temperatures. Both FC and TU increase the uptake of K+ by the embryonic axis. FC seems to act directly on H+ extrusion, but the mode of action of TU appears to be different. The results seem to indicate the importance of the activation of the ion transport process for the growth of the embryonic axis during early germination, and suggest a control of the growth of the embryo by part of the cotyledons. Physiological inhibitors such as ABA might be implied in the control mechanism.
