查询词典 oospores

The survival of oospores which were produced in the media was assessed after a winter. The methods promoting the oospore germination and the factors affecting the oospore germination were also investigated. Identfication of mating type, resistance to metalaxyl and isozyme genotype were performed on the F1 generations and parental isolates of oospores.

大豆疫霉病原菌的卵孢子主要通过黏附在种子表面以及混杂在种子里的土壤颗粒进行传播，也可通过带病种子传播。

Culture medium, water volume, root exudates of different crops, temperature, illumination affecting germination conditions of oospores of Phytophthora sojae studied in this reasch and compared the difference of germination of oospores of different race of Phytophthora sojae, filtrated the higher germination rate of strain and suitbable conditions combination of germination of oospores; The pure-line(Race 1) in virulence was obtained through isolation and culture and virulence identify of the second generation. The pure-line was analyzed by molecule method of ISSR. The results were summarized as follows:There was quite difference of germination rate of oospores on different culture medium.
