1987年在我站主持下,进行了稻瘟病茵生理小种室内测定工作。测定标本全部为早稻品种。测定采用孢子振落法,分离单孢培养。经培养后在秧苗4—5叶期接菌,接菌后保湿24小时后,并辅以人工喷雾保湿,以利发病。从测定的结果看,稻瘟病菌侵染早稻类型以及各品种间,存在较大差异,现简报如下。一、
In 1987 under the auspices of my station, carried out indoor testing of rice blast physiological races. All the samples were determined for early rice varieties. Determination of spore vibration method, isolated single spore culture. After the cultivation in the 4-5 leaves of seedlings inoculated bacteria, after inoculation 24 hours after moisturizing, supplemented by artificial spray moisturizing to facilitate the disease. Judging from the results of the assay, there is a big difference in the types of early rice invaded by Magnaporthe oryzae and among the varieties, and the brief report is as follows. one,
