日本东京苗圃技术公司最近采用液体培养方法,将水稻细胞组织培育成水稻秧苗获得成功,从而为工业化生产水稻秧苗开辟了道路。这项工业化生产水稻秧苗新技术效率极高,仅用1克细胞组织就能生产出4500株水稻秧
Japan’s Tokyo Nursery Technology recently adopted a liquid culture method that succeeded in cultivating rice cell tissue into rice seedlings, opening the way for industrialized production of rice seedlings. This industrialization of rice seedlings new technology is extremely efficient, only 1 gram of cell tissue can produce 4,500 rice seedlings
