高酸海棠“红勋1号”苗木嫁接繁育试验初报

Breeding Experiments on Seedlings of Malus prunifolia ‘Hongxun No.1'by Grafting

利用不同砧木、选择不同嫁接方式及时间,对高酸海棠"红勋1号"进行苗木繁育试验研究,结果表明,不同砧木、不同嫁接方法及时间均会对"红勋1号"成活率及生长产生影响:(1)选择不同砧木嫁接时,八棱海棠为砧木时成活率最高,黄海棠次之,野苹果为砧木时成活率最低;(2)使用不同嫁接方法对高酸海棠"红勋1号"嫁接后,成活率按顺序为双舌枝接>插皮接>劈接;(3)选择不同嫁接时间对高酸海棠"红勋1号"嫁接,黄海棠春季嫁接"红勋1号"成活率最高,为93%;八棱海棠的春季嫁接和秋季嫁接的成活率次之,均为92%;野苹果的秋季嫁接成活率最低,为84%。

Experiments of seedlings of Malus prunifolia ‘Hongxun No.1 ’were conducted by using different root-stocks and selecting different grafting methods & different time.Result shows that:different rootstocks,grafting methods &time all can affect the survival rate and growth :(1)while selecting different rootstocks for grafting,the survival rate is the highest by taking Malusrobusta as rootstocks,followed by Hypericumascyron,and the survival rate is the lowest while takingMalussieversii as rootstock;(2)afterMalusprunifolia ‘Hongxun No.1’were graf-ted by using different grafting methods,the descending order of the survival rate is double-whip graft>skin-insert whip graft>cleft graft;(3)Malus prunifolia ‘Hongxun No.1’were grafted by selecting different grafting time, Hypericumascyron grafted with Malus prunifolia ‘Hongxun No.1 ’can obtain the optimal survival rate,being 93%;the graft survival rate of Malusrobusta in spring & autumn are the second,all being 92%;the graft survival rate of Malus sieversii is the lowest,being 84%.
