砧木品种与茎尖嫁接成活率关系的研究

Study on the Relationship between Rootstock Varieties and the Survival Rate of Shoot-tip Grafting

[目的]明确砧木品种与茎尖嫁接成活率的关系。[方法]分别以枳(Poncirus trifoliata)、枳橙(Ruta"Citrange")和甜橙[Citrussinensis(L.)Osbeck]作为茎尖嫁接砧木,采用倒"T"字法对黄果柑、长泰芦柑、玉环高橙以及玉环柚进行茎尖嫁接脱毒。[结果]黄果柑和玉环高橙用甜橙作砧木成活率最高分别为75.0%和60.0%,长泰芦柑和玉环柚用枳橙作砧木成活率最高分别为46.7%和18.2%。[结论]茎尖嫁接成活率的高低与砧木和脱毒品种的亲和性有关,同一品种选用不同的砧木其茎尖嫁接成活率有差异。

[Objective] The aim was to study the relationship between rootstock varieties and the survival rate of shoot-tip grafting.[Method] Poncirus trifoliata,Ruta ＂Citrange＂ and Citrus sinensis（L.） Osbeck were prepared for rootstock in vitro.The citrus tristeza virus（CTV） of Huangguo,Changtai,Yuhuan Gaocheng and Yuhuan pomelo was eliminated by shoot-tip grafting using ＂T＂method.[Result] The highest shoot-tip grafting survival rate of Huangguo and Yuhuan Gaocheng grafted on Citrus sinensis（L.） Osbeck was 75.0% and 60.0% respectively.And the highest shoot-tip grafting survival rate of Changtai and Yuhuan pomelo grafted on Ruta ＂Citrange＂ was 46.7% and 18.2% respectively.[Conclusion] The shoot-tip grafting survival rate was related to the compatibility of rootstock varieties and cultivars.The survival rate of the same cultivars grafted on different rootstock varieties was different.
