为了筛选出促进接穗生长的优良砧木,以普通油茶本砧嫁接为对照,研究了陆川油茶、广宁红花油茶和香花油茶作为砧木对接穗普通油茶‘岑软3号’生长的影响。结果表明:定植4年后,以陆川油茶和香花油茶为砧木的‘岑软3号’嫁接苗株高、冠幅、茎和叶片的质量以及单株鲜果产量等指标均显著高于普通油茶本砧嫁接植株,陆川油茶和香花油茶作为砧木显著促进了‘岑软3号’的生长和结实,而以广宁红花油茶为砧木抑制了植株的生长和结实。利用主成分分析法得到综合得分值来评价4种砧木对接穗生长发育的影响,各物种根据综合得分由高到低排序依次为香花油茶、陆川油茶、普通油茶、广宁红花油茶。

In order to select some superior rootstocks for promoting scion growth,using Camellia oleifera rootstock ascontrol,effects of rootstock grafting from C.vietnamensis,C.semiserrata and C.osmantha on growth of scion-graftedC.oleifera‘Cenruan No.3’were studied.The results showed that height,crown width,stem mass,leaf mass,and freshfruit yield per plant of the grafted seedlings by using C.vietnamensis and C.osmantha as rootstocks were significantlyhigher than those by using C.oleifera as rootstock after4years of plantation.The rootstocks from C.vi...
