摘要

Several experiments were carried out to determine the effects of exogenously applied ABA on the water metabolism, and to clarify the endogenous ABA relationships in ozone-sensitivity under different soil water content in rice plants. The rice plants were cultivated in soil with 60, 80, and l00% of maximum water holding capacity and under submerged condition. The results of the experiments were as follows: 1. Ozone injury was reduced with increasing ABA content of which production was increased under water stress conditions. 2. Under water stressed conditions, the rate of water loss was decreased with increasing concentration of ABA applied exogenously. 3. It may be assumed that the ozone-sensitivity is closely related to the stomatal closure caused by the increased ABA content due to water stress.
