野生稻是宝贵的遗传资源。是水稻育种、稻种起源和稻作生态研究的重要物质基础。但在通常条件下,野生稻种子发芽率很低而且不整齐,给野生稻的保存、鉴定和利用研究造成很大的困难。国内外一些学者曾做过不少发芽技术研究,都未能找到完全打破种子休眠,促进发芽的好方法。广西农科院品种资源研究所从1987年开始对药用野生稻和普通野生稻种子的发芽技术进行了专题研究,找到了大批量种子发芽的方法,发芽率达到90％左右。

Wild rice is a valuable genetic resource. It is an important material basis for rice breeding, rice origin and rice ecological research. However, under normal conditions, the germination rate of wild rice seeds is very low and irregular, which has caused great difficulties in the research on the preservation, identification and utilization of wild rice. Some scholars at home and abroad have done a lot of germination technology research, have failed to find a good way to completely break the seed dormancy and promote germination. Guangxi Academy of Agricultural Sciences, Institute of Resources and Resources began from 1987 on the wild and common wild rice O. sativa germination technology research project to find a large number of seed germination methods, the germination rate of about 90%.
