日本苗圃技术公司采用液体培养法培育成功水稻植株。他们从稻种胚中取出愈伤组织（即细胞团）在培养基中培养。培养期间，用搅拌机把愈伤组织搅成细粒，然后将其放入容器进行液体培养。试验证明，通气条件以氧气95％，Th氧化碳50％最为适宜。这项技术尚待解决的问题是如何处理 Japanese nursery technology company using liquid culture method to cultivate successful rice plants. They removed callus (ie, cell mass) from the rice embryos and cultured them in culture. During cultivation, the callus is finely divided with a blender and then placed in a container for liquid culture. Experiments show that aeration conditions to oxygen 95%, Th 50% of the most appropriate carbon monoxide. The problem remains to be solved by this technology
