| 摘 要： | 为进一步揭示砧木的矮化机理 ,以SH系矮化砧木及相应中间砧红富士苹果为试材 ,在生长季测定砧木枝条及嫁接部位的水分输导阻力。结果表明 ,SH系砧木枝条及嫁接部位的水分输导阻力 ,随砧木矮化程度的升高而增大 ,表明水分输导阻力的增加 ,是导致嫁接树矮化的原因之一。

| Abstract: | The experiment was carried out with SH stocks and red Fuji young apple trees grafted on different interstocks. The water transmitting resistance of the shoots were studied in order to discover the dwarfing mechanism. We found that the resistance in the stem of very dwarf stocks (SH 5, SH 38 ) was higher than that of semi-dwarf stocks (SH 40 , SH 28 ). The grafted area of stocks had the same thing. All the results showed that the change of water transmitting resistance was one of the main reasons to make the tree dwarfing. |
