This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T
