1976年,我们开始了一项旨在确定由隐性矮化因(dw)桃树结实力的研究.这种突变基因抑制了植株长势(约为标准树的1/3),并缩短了枝条节间长度.栽后第2和第3年所得产量资料表明,带矮化基因 dw 的桃树比一般桃树结果早。同时还表明,矮化桃树的单位面积产量明显超过标准桃树。 In 1976, we started a study to determine the fruiting ability of the peach tree by the recessive dwarf gene (dw), which inhibits plant growth (about 1/3 of the standard tree) and shortens the branches Internode length. The yield data obtained in the second and third years after transplanting showed that the peach tree with the dwarf gene dw was earlier than the peach tree. At the same time, it also showed that the yield per unit area of ​​dwarf peach trees significantly exceeded that of standard peach trees.
