我国植物资源丰富,但因多种原因使不少植物濒临灭绝,急待加速繁殖。如安徽省的软籽石榴,过去满山遍野,可是到八十年代,仅存七株老树。又如太和樱桃品质优异,曾为明、清年代的贡品,可到1984年,太和县仅剩2000多株老树。太和樱桃用分株繁殖速度慢,用硬枝扦插生根率只3—5％,并表现出落叶和溃烂。 Our country is rich in plant resources, but due to a variety of reasons, many plants are on the brink of extinction, and we urgently need to speed up their breeding. For example, the soft-seed pomegranate in Anhui Province was covered with mountains and mountains, but by the 1980s, only seven old trees remained. Another example is too good and cherry quality, once the Ming and Qing tribute, until 1984, Taihe County, only more than 2,000 trees. Toohua and cherry reproduce slowly with ramets, hardwood cutting rooting rate of only 3-5%, and showed decay and decay.
