摘要：

Abscisic acid (ABA) was found to increase the accumulation of 36Cl, total Cl, 22Na and total Na+ in roots of intact bean seedlings. After an initial promotion. ABA inhibited longdistance transport of these ions from the root to the shoot. However, it consistently inhibited both uptake and transport of 42K and total K+ in intact bean seedlings. A promotion of net 36Cl influx (ψoc) and its accumulation in the root (Q*v) concomitant decrease in transport index (long‐distance transport as percentage of total influx) showed that ABA stimulates ‐36Cl transport at the tonoplast. It inhibited H4 extrusion and net 86Rb influx which agrees with a cation exchange theory K+/Rb+ transport. Copyright © 1979, Wiley Blackwell. All rights reserved
