南方红豆杉主梢隐性腋芽嫁接试验

Experiment on Recessive Axillary Bud Grafting of the Main Shoots of Taxus chinensis var.mairei

研究不同部位的芽、接穗芽是否带叶片、不同嫁接绑带等对南方红豆杉嫁接成芽、抽梢成活率和主梢形成率的影响。结果表明:以3年生南方红豆杉为砧木嫁接时,"7"字型芽接法可用于不同部位芽的嫁接,接穗用主梢隐性腋芽带有1片叶,采用食品级保鲜膜做嫁接绑带,可促进接穗提早成芽,提高主梢成活率,且抽主梢形成完整冠型,嫁接效果相对较好。

Based on the research on shooting survival rate and formation rate of main shoot of Taxus chinensis var.mairei effected by different buds of different parts,scion buds with or without leaves and different grafting bands on the grafting bud formation,the results showed that with 3-year-old Taxus chinensis var.mairei used as rootstock grafting,the ″7″ bud grafting method used to graft buds of different parts,the recessive axillary buds of the main shoot with one leaf used as scion,and food preservation film used as grafting band,the earliness of scion could be promoted,the survival rate of the main shoot could be increased,and the main tip could be sprouted to form a complete coronal pattern.The grafting effect was relatively better.
