无性繁殖的进展及其在无性系林业中应用前景

本文对无性繁殖的历史、传统的无性繁殖技术(扦插、压条和嫁接繁殖)、现代组织培养繁殖法(器官培养、愈伤组织或细胞培养、原生质体培养、单倍体培养)进行了全面的综述,对无性繁殖的主要限制因子及可能的解决方法进行了讨论。

Development of Asexual Reproduction and Its Application Prospect in Clonal Forestry

The history of asexual reproduction, traditional asexual techniques and modern tissue cultivation reproduction are summarized. Although asexual reproduction plays a more and more important role in forestry production, there still exist some physiological and economic restrictions. The senescence effect could not be essentially overcome. The application of tissue cultivation reproduction in forestry production needs further amplification, and artificial seed research is still in investigation stage. The author holds that it is not practical to fully substitute the asexual reproduction techniques for traditional seed reproduction at present. It is wise to avoid exaggerating the superiority of clonal forestry, and to copi-bining breeding procedure with development planning of clonal forestry.The development of clonal forestry should be integrated with genetics, silviculture,physiology, ecology, pathology and other related disciplines.
