| 摘 要： | 不同砧木红星苹果树含水量的日变化呈Ｖ形曲线。以乔砧树最高,Ｍ７中间砧树次之,Ｍ９中间砧树较低。含水量的日变化与水势的日变化基本呈正相关。地上部含水量与砧木解剖构造有关,矮砧树地上部含水量较低是导致树体矮化的因素之一

| Abstract: | Diurnal changes of relative water content of Starking apple trees on different rootstocks presented as a "V" shaped curve. The relat ive water content of trees on standard and on M7 interstocks were significantly higher than that of the tree on M9 interstocks. Positive corrlatictn was found between the diurnal changes of relative water contentt and water potential. The relative water content relates to anatomical structure in apple tree. The lower level of water content in dwarf rootstock is one of the factor. inducing to for dwarfing. |
