Abstract
The effects of three plant growth regulators(PGRs) of TIBA,S_(3307) and DTA-6 on abscission and polygalacturonase (PG) activities of soybean flowers and pods were investigated by spraying in V3(third-node stage),R1(beginning bloom stage) and R3(beginning pod stage) stages,respectively,and under the field planting conditions.Glycine max(L.) Merr.cv.'Hefeng50' was used as the experimental material.The results showed that:the rate of abscission of soybean flowers and pods was lowered by spraying TIBA,S_(3307) and DTA-6 in all the stages;The PG activities of soybean flowers and pods were decreased after spraying TIBA, S_(3307) and DTA-6 in V3 stage;Plant growth regulators decreased PG activity significantly after spraying at R1 stage and the regulation effect of DTA-6 was the best.Plant growth regulators decreased PG activity in pod and abscission pod after spraying at R3 stage and the regulation effect of TIBA was the best.In conclusion,the comprehensive regulation effect is S_(3307)DTA-6TIBACK in V3 stage;DTA-6TIBAS_(3307)CK in R1 stage; DTA-6TIBAS_(3307)CK in R3 stage.
