油桐无性繁殖是保持油桐优良性状,发展优良品种和单株的有效途经。千年桐雌雄异株,通过嫁接可以发展雌株。在三年桐中具有很好丰产性能的纯雌花类型,由于它不具雄花,靠异株授粉,所结果实均为杂种,后代分离大。要发展这类优良类型,目前也只有靠无性繁殖。此外,无性繁殖吊是建立无性系种子园的必要手段。嫁接是无性繁殖的主要方法。其中芽接具有对穗条利用率高,方法简便,成活率高等优点。地处南亚热带的广西林科所曾通过圃地培育砧木,就地嫁接三年桐和千年桐,成活率多
Tung tree asexual reproduction is to maintain the fine traits of tung tree, the development of fine varieties and effective way to single. Millennium Tong dioecious, female plants can be developed by grafting. In the three years in Tongzhong have a good performance of pure female type of flower, because it is not male flowers, pollination by heterosexual, the results are hybrid, large offspring. To develop such good types, only by asexual reproduction. In addition, cloning trays are a necessary means of establishing clonal seed orchards. Grafting is the main method of asexual reproduction. Which bud with a high utilization of the spike, the method is simple, high survival rate advantages. Located in the southern subtropics of Guangxi Linke had nursery nurturing rootstocks, three-year local grafting Tong and Trinity, survival rate and more
