【摘要】 从变异类型、变异起源、影响因素、遗传机理及变异检测等方面综述了植物体细胞无性系变异研究的新进展,对1977年以来有关林木体细胞无性系变异的研究资料进行了全面介绍,并就林木体细胞无性系变异研究中存在的问题进行了讨论,认为深入系统的开展林木体细胞无性系变异研究,对于利用组织培养技术进行林木遗传改良和良种快速繁殖具有十分重要的意义。更多还原

【Abstract】 New progress in such aspects as variation types, origination, influencing factors, genetic mechanism and detecting methods of plant somaclonal variation is summarized. The information on somaclonal variation in forest tree since 1977 is fully introduced. Some problems existed in forest tree somaclonal variation study are discussed. It is thought that doing further research systematically on somaclonal variation is very important for genetic improvement and fast propagation of forest tree by means of tissue culture technique.更多还原
