Wild flower Sanguisorba officinalis L.was treated by plant growth regulator chlormequat(CCC).The height and endogenous hormones in leaves were determined.The results showed that CCC could significantly reduce the height and inhibit the synthesis of GA_3,IAA,ZT and they were reduced as the content of CCC increased.Meanwhile,CCC could effectively increase and decrease the content of ABA at vegetative growth stage and reproductive stage respectively.Accordingly,CCC can improve the hardiness and put off senescence of Sanguisorba officinalis L.
