嫁接插条扦插繁殖果树的技术已应用很多年了,主要用于葡萄和柑桔。最近已试用于其他树种,如山茶、杜鹃花、美国黄杉、桧柏、苹果、橄榄、玫瑰、梨和李。采用嫁接插条扦插,除对难发根的树种或品种提供了无性繁殖的可能性外,还可减少获得嫁接树所需的时间。果树无性繁殖常采用的程序是在已生根的插条上嫁接,因此得到一株幼树至少要两年时间:一年用于插条的生根,一年用于接穗的发育。如头年末,插条生长量未达到嫁接要求,就可能还 Grafting Cuttings Propagation of fruit trees has been used for many years, mainly for grapes and oranges. It has been recently tested on other tree species such as camellia, rhododendron, American Douglas Fir, Cypress, Apple, Olive, Rose, Pear and Lee. The use of grafted cuttings, in addition to providing the possibility of asexual reproduction of difficult-to-root species or varieties, also reduces the time required to obtain a grafted tree. The usual procedure used for asexual reproduction of fruit trees is grafting on cuttings that have already been rooted, so it takes at least two years to get a sapling: one year for rooting of cuttings and one year for scion development. As the end of the first year, the growth of cuttings did not meet the grafting requirements, it is possible
