嫁接杂交是茶树无性杂交育种的又一种新方法 ,其程序是首先用秋水仙素动摇旧的遗传保守性 ,再用遗传性已经动摇的有机体接受穗 /砧组合的内环境条件的蒙导教养 ,最终形成似砧型的茶树新品种。但又因秋水仙素对体细胞的加倍为同源染色体的加倍 ,而生长点整体细胞中各细胞核的加倍倍数又存在着差异 ,由此产生的嫁接杂交种可从遗传上解决茶树开花结籽的遗传特性 ,从而为人工培育高产型的茶树新品种开创了一条崭新的途径 Graft hybridization is another new method of clonal hybridization of tea plants. The procedure is first to recuperate the old genetic conservation of colchicine and then recuperate the hereditary already-shaken organism to accept the internal environmental conditions of ear / anvil combination , Eventually forming an anvil-like new varieties of tea trees. However, doubling of somatic cells by colchicine resulted in doubling of somatic cells, and doubling of doubling times of nuclei in whole cells of growing points was different. The resulting hybrids could genetically resolve the flowering and seeding of tea plants Genetic characteristics, thus creating a new way for cultivating high-yielding varieties of tea tree by artificial cultivation
