摘　　要：为明确美博桃树体生长表现,以桃树优系H和I为对照,对美博桃的树体生长情况和枝芽特性进行了调查。结果表明:美博桃生长旺盛,与对照相比,树体更高大、干更粗、枝展更大;发育枝较多,且其长度和粗度较大,分枝较多;各类果枝的长度和粗度均较大,花束状果枝比例较低,徒长性果枝比例较高,主要结果枝是长果枝和中果枝;芽有11种类型,花芽起始节位相对较高,花芽和叶芽总量较少;发育枝、徒长性果枝及其上二次枝顶部有大量连续盲节。To make clear the tree growth of Meibo peach,taking the good peach strains H and I as the control,the tree growth,branch and bud characteristics of Meibo peach were investigated.The results showed that Meibo grew vigorously.Compared with the control,Meibo had the tallest tree,thickest trunk diameter and biggest branch width.It had more developmental branches,which were long and thick.Each kind of fruiting branch was longer and thicker.The ratio of bunch flower fruiting branch was the lowest,while that of spindling fruiting branch was highest.The long and medium fruiting branches were the major fruiting branches.There were eleven kinds of buds,the initial node of flower bud was relatively higher,and the total amount of flower bud and leaf bud was less.There were many consecutive nodes without buds on the top of the developmental branch,spindling fruiting branch and their second shoots.
