目前,在日本认为比较实用的矮化砧木只有M、MM和CG系列砧木。适宜每平方米栽植100～200株的砧木有:M_(27)、M_8、M_9,M_(26)、CG_(10)、CG_(23)、CG_(24)、CG_(80)。矮化砧木的共同特点是使树冠矮化、早期结果,促进果实膨大,含糖量高,成熟期早。其缺点是根的皮层厚,木质脆。现将几种主要矮化砧木特性介绍如下。
At present, only dwarfing rootstocks in Japan are considered as M, MM and CG series rootstocks. The rootstocks suitable for planting 100-200 plants per square meter are M 27, M 8, M 9, M 26, CG 10, CG 23, CG 24 and CG 80. The common feature of dwarfing rootstocks is dwarfing canopy, early results, promoting fruit enlargement, high sugar content, and early maturity. The disadvantage is the root of the cortex thick, crisp wood. Now several main dwarfing characteristics of the stock as follows.
