用本地感病的红花品种,对P.carthaml的孢子阶段和生活史进行了研究.结果指出,种子经冬孢子粉拌菌后播种,幼苗罹病后在同一块病斑上先后产生性孢子、夏孢子和冬孢子。明确了性子器后发育生成的孢子防段为初生夏孢子.为此P.carthami应归属为单主寄生,缺锈孢型锈病菌. Using the local susceptible safflower cultivars, the spore stage and life history of P.carthaml were studied.The results showed that the seeds were sowed after the winter spore powder mixture, Ureaser and winter spores. It is clear that the conidia of sporophytes developed after the development of protozoa are primary uredospores, and P.carthami should be attributed to a single dominant parasitism and rust rust spore rust.
