1 前言多种植物采用试管内的无性繁殖技术已被开发。确立林木的组织培养繁殖技术的树种有几十种。采用这种方法大量繁殖无菌苗必须经过各种严格的驯化过程才能得以保证。可是,这种大量繁殖技术及其驯化过程操作很烦杂。考虑便于生产上的应用,在试管无性繁殖的基础上又进行了改良。把植物的分生组织或胚,用凝胶包埋制作成与天然种子相似的种子,称作人工种子。目前,采用这种方法,在无菌的条件下 1 Introduction A variety of plants have been developed using in vitro in vitro propagation techniques. There are dozens of species that establish the technology of tissue culture and propagation of trees. In this way, mass propagation of sterile seedlings must be subjected to various strict domestication processes to be guaranteed. However, this mass propagation technique and its domestication process are cumbersome to operate. Considering the ease of application in production, the test tube asexual reproduction based on the improved. The plant’s meristems or embryos, gel-made into seeds similar to natural seeds, known as artificial seeds. Currently, using this method, under sterile conditions
