Abstract:
With eight peony‘Xiangyu’,‘Luhehong’,‘Huhong’,‘Yaohuang’,‘Taohongfeicui’,‘Zhihong’,‘Taohongxianmei’,‘Feiyanhongzhuang’ as materials,the sugar metabolism and relative water content in the petals were investigated,to clarify the effect of soluble sugar and water content on florescence during flowering opening and senescence.The results showed that soluble sugar and the water content of petals might be important for flowering opening and senescence in peony.During the flower opening,the amount of soluble sugar(glucose and fructose) increased rapidly,sucrose was decreased constantly.The water content was influenced by soluble sugar.Peony control the flower growth by adjusting the amount of water content through soluble sugar.
