Abstract: Sugar accumulation and sucrose related enzyme activities of Yanguang(Prunus Persica(L) nectarine) fruits in greenhouse.The results showed that in foliar application of KH2PO4 treatment,activities of fruit sucrose metabolizing enzymes were significantly increased.Foliar application of KH2PO4 when fruit was young significantly increased glucose and fructose content in young fruits,but had no significantly influence on sucrose content,and until harvest time there were no significantly difference in sugar content.Foliar application of KH2PO4 before coloringsignificantly increased fruit sucrose content,but had no significantly influence on glucose and fructose content.The results indicated that foliar application of KH2PO4 treatment could increase fruit sugar content by increasing activities of sucrose metabolizing enzymes.

Key words: KH2PO4, Greenhouse, Nectarine, Fruit, Sugar accumulation, Sucrose-metabolizing related enzyme
