离体培养五个苹果品种的梢尖(长约5—8毫米),它们所产生的新梢显然来自侧生分生组织。培养物在十二个月内每三周繁殖近5倍,而且80％以上的新梢形成了根,产生的植株有90％以上已在盛土的花盆中成长。此法使快速繁殖自根苹果树成为可能,对现代高度密植果园制度具有重大的经济效益。
The tips of five apple cultivars (about 5-8 mm in length) were cultured in vitro, and the tips they produced apparently came from the lateral meristem. Cultures breed nearly five-fold every three weeks in twelve months, and more than 80% of the shoots formed roots and more than 90% of the plants produced had grown in pots of rich soil. This method makes it possible to breed rooted apple trees rapidly and has significant economic benefits to modern highly-intensive orchards.
