摘　　要：2006年对9个晚熟桃品种进行了引进栽培试验,观察测定了各品种的物候期、植物学特性、经济性状和抗逆性。结果表明,到2009年,各品种全部结果,但各个品种间的产量、品质差异较大。9个引进品种中,白玉长势中庸,树形开张,成花容易,早果性强,以中短果枝结果为主,夏梢抽生少,栽培管理粗放,较早熟,平均单果重261.5 g,果顶平,着色好,可溶性固形物含量11.4%,抗性强;脆蜜桃生长势特强,自然生长树形为杯状形,成枝率强,以中长果枝结果为主,夏梢抽生多,坐果率高,平均单果重达213.5 g,可溶性固形物达12.3%;晚黄金生长势强,树形开张,以中长果枝结果为主,坐果率高,平均单果重213 g,可溶性固形物达到12.4%;冬丰冬桃生长势特强,树形直立,夏梢抽身特别多,成枝率强,品质好,丰产性有待进一步观察。The phenophase,botanic characteristics,economic characters and stress resistance of 9 introduced peach varieties were observed from 2006 to 2009.The results showed that all introduced peach varieties bore fruits in 2009,and there were obvious difference in yield and quality among 9 introduced peach varieties.The growth performance of Baiyu variety is common,opening tree shape,early maturity,fruit-bearing position mainly on middle and short branches,261.5g average single fruit weight,flat fruit tip,good coloring,11.4% soluble solids and strong resistance.The growth performance of Cuimi variety is very strong,cup tree shape,high effective branch rate,fruit-bearing position mainly on middle and long branches,high fruit-setting rate,213.5g average single fruit weight and 12.3% soluble solids.The growth performance of Wanhuangjin variety is strong,opening tree shape,fruit-bearing position mainly on middle and long branches,high fruit-setting rate,213.0g average single fruit weight and 12.4% soluble solids.The growth performance of Dongfengdong variety is very strong,erect tree shape,high effective branch rate and good quality and its high yielding ability should be further observed.
