摘要
一天中不同时间的桃树贮存水的调节能力各异 :在上午贮存水为茎液流总量的 14 % ,中午为 7% ,下午为 2 3%。不同部位贮存水的相对调节能力大小也有明显的差异。其由大到小顺序依次为主干、主根、枝条、侧根、叶片、细根、果实 ,这种差异是由各部位水容、阻力和体积的不同引起的 ,且基本上不随时间的变化而变化。
The water storage of different parts of peach was different in a day. The total quantity of sap flow was about 14% in morning, 7% and 23% in noon and afternoon. The order of relative water storage adjustment was: stem>main root>branch>lateral root>leaf>fibrous root>fruit. These differences were result from water storage capacity, transport resistance and volume of water in organs.
