以八棱海棠(Mulus robusta)、平顶海棠(M.prunifolia)、圆叶海棠(M.prunifoliavar.ringo)、西府海棠(M.micromalus)、红果海棠(M.sieboldii)和珠美海棠(M.zumi)为砧木,嫁接“绿宝”苹果(M.domestica‘Bramley′s seedling’),对接穗与砧木新梢的解剖结构以及嫁接口的解剖结构进行了观察测定,以了解“绿宝”苹果与不同砧木的嫁接亲和性。结果表明:“绿宝”苹果与八棱海棠、平顶海棠的枝皮率差异不显著,新梢横断面的组织结构相差较小,而与珠美海棠和红果海棠的枝皮率存在显著差异,且组织结构相差较大;“绿宝”苹果嫁接在八棱海棠和平顶海棠上,其嫁接口砧穗的结构差异较小,愈合良好;而嫁接在珠美海棠和红果海棠上,接口砧穗的结构差异较大,愈合较差,砧穗较易分离。综合分析认为,八棱海棠、平顶海棠和圆叶海棠为“绿宝”苹果适宜的嫁接砧木。
The leaves of M. robusta, M. prunifolia, M. prunifolia var. Ringo, M. microcromalus, M. sieboldii and M. begonia (M. zumi) as rootstocks and grafting “M. domestica’Bramley’s seedling ’”, the anatomical structures of the scion and rootstock shoots and the anatomical structures of the grafted mouth were observed and measured to find out whether “green Po ”Apple and different rootstock grafting affinity. The results showed that there was no significant difference in the bark-skin ratios of “Emerald apple” and “Bailun” and “Hommelopsis” Difference, and the difference of organizational structure was larger; “Emerald apple” was grafted on Begonia oleander and Begonia capitata, the difference of structure of the rootstock was smaller and healed well; The structure of the interface anvil spike is quite different, the healing is poor, the scion is easier to separate. A comprehensive analysis shows that Balenghaitang, Pingdingshangtang and Begonia are suitable for “Emerald” apple grafting.
