摘　　要：以1.5年生的水红簕杜鹃(Bougainvillea buttiana'Miss Manila')和小叶紫簕杜鹃(Bougainvillea glabra'Sao Paulo')盆栽苗为试材,采用不同的控水方式(间隔控水和持续控水)研究2种簕杜鹃的开花情况和植物内源激素变化情况,以期为调控簕杜鹃花期提供技术参考.结果表明,间隔控水有利于水红簕杜鹃GA_(3)、ABA的升高、IAA的下降以及形成较小的ABA/GA_(3)峰值、较大的ABA/IAA峰值,并提高可溶性糖含量,促进植株开花,提高成花数量.小叶紫簕杜鹃采用间隔控水可促进GA_(3)、IAA、ABA的升高以及形成较大的ABA/GA_(3)峰值、较小的ABA/IAA峰值,并提高可溶性糖含量,促进植株开花并延长花期.可见,2种簕杜鹃的花期调控应采用间隔控水方式有较好的效果.Potted seedings of Bougainvillea buttiana'Miss Manila'and B.glabra'Sao Paulo'which has been planted 1.5 years were used as test materials,interval water control and continuous water control were used,effects of different water control methods on flowering and plant endogenous hormones of two B.glabra were studied,in order to provide technical reference for regulating the flowering period.The results showed that interval water control resulted in the increase of GA_(3)and ABA,the decrease of IAA,the formation of a smaller ABA/GA_(3)peak and a larger ABA/IAA peak,the increase of soluble sugar content,and the promotion of plant flowering and the number of flower formation of B.buttiana'Miss Manila'Interval water control could promote the increase of GA_(3),IAA,and ABA,and form a larger ABA/GA_(3)peak and a smaller ABA/IAA peak,and increase the soluble sugar content,thus promoting flowering and prolonging the flowering period of B.glabra'Sao Paulo'.The results showed that the method of interval water control should be used to regulate flowering period of the two species of B.glabra,which was more effective.
