%X The present study provided the evidence that exogenous NO and ABA regulated the stomatal movement in poplar leaves.It showed that different levels of SNP and ABA induced the stomatal closure in detached leaves.NO enhanced stomatal closure that induced by ABA.The effect of NO and ABA on stomatal closure was suppressed by c-PTIO,a specific NO scavenger.It was confirmed that NO involved in ABA-mediated stomatal movement.The activities of POD were dramatically inhibited,but those of SOD hardly decreased in different levels of SNP and ABA treatment.However,in vitro experiments indicated that the activities of POD were dramatically inhibited by NO,but not ABA.The results demonstrated that NO mediated ABA-induced stomatal closure of trees,and was a signaling component of ABA-induced stomatal closure.
