掌握果树细胞分裂的规律,是研究果树遗传的理论基础,是探索果树系统发生和对种质资源进行分类与鉴定的重要依据。而观察细胞分裂的方法,则是进行果树选育种工作,特别是采用组织培养手段所必须掌握的基本技术。然而有关这方面的研究资料,尤其是减数分裂,却极为贫乏.国内至今尚无 Grasping the law of cell division of fruit trees is the theoretical basis for studying fruit tree genetics and an important basis for exploring the occurrence of fruit tree systems and for the classification and identification of germplasm resources. The observation of cell division method, it is carried out breeding breeding fruit trees, especially the use of tissue culture means must master the basic technology. However, research data on this area, especially meiosis, are extremely poor.
