青钱柳繁殖技术研究进展及发展趋势

Research Progress and Prospects of Propagation Technologies for Cyclocarya paliurus

综述了近年来青钱柳有性繁殖、无性繁殖等方面的研究成果,并探讨了今后其繁殖技术发展方向和急需解决的关键技术。结果表明,有性繁殖的研究重点是其种子休眠机理及其解除方法,关键技术在于物理、化学、变温等方法联用以及生长调节剂在解除种子休眠时的协调使用;扦插、组培繁殖是今后青钱柳快繁技术研究的重点;扦插繁殖的关键技术为筛选最适宜扦插枝条生根存活的环境因子,而组培繁殖的关键技术在于培养基优化、植物生长调节剂添加、外植体脱毒技术等方面。

It was reviewed the progress of sexual and asexual propagation technologies for Cyclocarya paliurus according to the litera- ture in recently years, and was also discussed the research focus and key technologies on the propagation. The result showed that seed dormancy mechanism and methods to break dormancy in Cyclocarya paliurus was the focus of sexual propagation, and the key tech- nologies were the combined use of physical methods, chemical method, balance cooling ＆ rewarming method and growth regula- tor. Both of the cuttings and tissue culture propagation were the focus of the rapid propagation. Further more, the key technologies of cuttings propagation were the optimum environmental conditions selected for the cutting＇ s rooting, survival and growth ; And the key technologies of tissue culture propagation were that medium optimization, plant growth regulator added, and explants＇ detoxification techniques.
