坦噶尼喀通常用种子来繁殖腰果树。由于腰果树是异花授粉植物,因此,任何一株母树的后代都是杂合型的。高产树的种子不一定就能长成高产树。在纳钦瓜(Nachingwea),曾经试用过芽接、插条和嫁接等无性繁殖方法来繁殖腰果树,结果没有一种方法获得成功。可是在纳钦瓜试用空中压条法却已获得相当的成功,如果在操作技术方面加以改进,还可大大 Tanganyika usually breeds cashew trees with seeds. Because the cashew tree is a cross-pollination plant, the progeny of any of the mother trees are heterozygous. High-yielding tree seeds do not necessarily grow into high-yielding trees. In Nachingwea, there have been tried apomictic, cuttings, and grafting clones to breed cashew trees and none of them succeeded. However, in Naqin melon trial of air pressure method has been quite successful, if the operation technology to be improved, but also greatly
