摘要： 以3年生阳丰柿子幼树为试材,在幼树的萌芽期、盛花期和新梢旺长期通过对其不同角度的拉枝处理,研究拉枝对甜柿幼树生长发育的影响.结果表明:拉枝能明显提高甜柿叶片中可溶性糖和淀粉含量,但其变化规律不明显,阳丰萌芽期处理枝条的可溶性糖含量总体要高于盛花期处理枝条,其盛花期枝条的还原糖含量以90°拉枝的平均水平最高,阳丰叶片的淀粉含量以110°拉枝处理最高;阳丰叶片叶绿素含量随拉枝角度的增大呈减小的趋势,其叶片蛋白质含量各拉枝角度均高于对照.

Abstract: In this experiment,3-year-old Yangfeng persimmon saplings as test materials,the budding young trees,flowering and vigorous shoots from different angles by bending branch of its processing to study the effects of persimmon saplings bending branch growth.The results showed that:bending branch could significantly improve the persimmon leaf soluble sugar and starch content,but its variation was not obvious,Yangfeng infancy processing branches soluble sugar content was higher than the overall processing flowering branches,twigs to restore its overrall sugar content in the average level of 90° bending branch of the highest starch content Yangfeng leaves to 110° bending branch was the highest; Yangfeng leaf chlorophyll content with branch angle decreased,which leaves protein content of branch angles were higher than the control.

Key words: Persimmon, Bending, Growth and development
