为了验证砧木根皮率及导管等,对苹果实生砧不同类型的早期预测乔化和矮化的作用。选用了接穗为金冠的8种19个类型的苹果实生砧,进行观察比较,其结果是不同砧木的根皮率与干周(代表树的大小)间是正相关,其中有了种砧木差异明显,其余不显著,观测根的导管大小和密度,即导管面积与千周间呈负相关,但不显著,因此可以认为实生砧的变异大,为只用根皮率及导管面积来预测实生砧的乔化和矮化是不易准确的。
In order to verify the rootstock rootstock rate and catheter, etc., different types of apple rootstock early prediction of Qiao and dwarfing role. The results showed that there was a positive correlation between the root bark rate of different rootstocks and the dry week (representing the size of the tree), among which there were significant differences among species rootstocks, The other is not significant, the root canal size and density of the observation root, that is, the catheter area was negatively correlated with the week, but not significant, so you can think of a large variance in the rootstock, root bark rate and catheter area to predict the actual anvil Qiao and dwarf is not easy to accurately.
