【摘要】 辣椒疫病是新疆辣椒上的重要病害之一,关于辣椒疫菌(Phytophthora capsici)的越冬规律,国内末见详细报导,本文就此对该菌在新疆的越冬规律进行了比较全面的研究。查明了该菌在种子上不能越冬;因菌丝耐寒性差,在新疆田间也不能成为初次侵染来源;其主要侵染来源是土壤中和植物病残体上越冬的卵孢子。更多还原

【Abstract】 Pepper Phytophthora blight is one of the most important diseases of the peper in Xinjiang. There is no detailed report about the over wintering of Phytophthora capsici in this area. In this paper, by making a systematic study of the disease, we found that Phy-tophthora capsici could not overwinter in seeds. The mycelium had poor ability to resist the cold, so, in Xinjiang it was not possible to be. the source of infection in the fields. The primary source of infection was the oospore overwintered in soil and plant survival.更多还原
