腰果一般采用种子繁殖。因腰果是异花授粉作物,由种子长成的植株是异质的,实生后代的形态性状(如树高、树围和冠幅等)和经济性状(如产量和腰果大小等)的变异性很大。因此,人们在采用实生繁殖时都十分重视选择优良的母树。理想的母树应年年结果,年平均腰果产量不低于20公斤,且母树的一级分枝和侧枝较多,树冠伸展。印度Anakkayam腰果研究站第20号腰
Cashews generally use seed breeding. Because cashew nuts are cross-pollination crops, plants grown from seeds are heterogeneous, and morphological traits (such as tree height, tree shrub and crown width) and economic traits (such as yield and cashew size) of the offspring are heterogeneous Great. Therefore, people pay great attention to the selection of good mother trees when they adopt real breeding. The ideal mother tree should be annual results, the annual average cashew yield of not less than 20 kg, and the mother of the first branch and collateral more crown extension.
