oospore

The optimum temperature for oospore germination was 18-24 ℃ .

卵孢子在两种基质上萌发最适温度为18-24℃。

The primary source of infection was the oospore overwintered in soil and plant survival .

其主要侵染来源是土壤中和植物病残体上越冬的卵孢子。

A1 and A2 sporangium proportion markedly affected the oospore formation quantity .

A1和A2菌株中孢子囊不同比例对卵孢子产生影响很大，当比值为1∶1时卵孢子产生量最大；
