‘红羽1号’和‘红羽2号’油茶新品种(种间)嫁接亲和性
|
摘要
为掌握‘红羽1号’和‘红羽2号’油茶新品种繁育的相关技术参数,本研究以普通油茶作砧木,‘红羽1号’和‘红羽2号’油茶新品种作接穗进行大树换冠,开展嫁接成活率及接穗新梢生长量的对比试验研究。结果表明:‘红羽1号’和‘红羽2号’油茶新品种与普通油茶嫁接亲和力强,嫁接成活率分别为93.75%、94.74%,芽成活率分别为88.33%、88.89%。利用‘红羽1号’作接穗其接穗的生长及抽梢情况单株间差异极显著(P <0.01),但利用‘红羽2号’作接穗只是接穗的生长单株间差异显著(P <0.05);‘红羽1号’和‘红羽2号’新品种间的嫁接生长情况差异不显著。
In order to find out the relevant technical parameters of the breeding of two new Camellia semiserrata varieties‘Hongyu 1'and‘Hongyu 2',we used Camellia oleifera as root-stock and‘Hongyu 1'and‘Hongyu 2'as scions to develop comparative study on grafting survival rate and shoot growth of scion. Resultsshowed that‘Hongyu 1'and‘Hongyu 2'had strong affinity with C. oleifera,which grafting survival rateswere 93.75% and 94.74% and survival rates of buds were 88.33% and 88.89%,respectively. The growth ofscion and condition of tassel of individual plant using‘Hongyu 1'as scion were extremely significant(P <0.01),while that was significant(P <0.05) using‘Hongyu 1'as scion. There was no significant differencein graft growth between‘Hongyu 1'and ‘Hongyu 2'(P > 0.05).
