【摘要】 在不同温度、不同ｐＨ值的ＰＤＡ平板上培养油菜菌核病菌核和菌丝块，观察菌核萌发的最适温度和菌丝生长的最适温度、最适ｐＨ值，结果表明菌核萌发的最适温度为２４～２８℃，菌丝生长的最适温度为２０～２８℃，３５℃为菌丝的致死温度，菌丝生长的最适ｐＨ值为４７～８５。更多还原

【Abstract】 The effects of temperature and pH value on the mycelium development、sclerotia germination and sclerotia formation of Sclerotia sclerotium were studied with PDA medium The suitable temperature of sclerotia germination or mycelium development was ranged from 10-31℃, and the favourable temperature of sclerotia germination was ranged from 24-28℃ The mycelium development was favourable at 20-28℃ and the mycelium can’t survive under 35℃ The favourable pH value for mycelium growth was 4 7-8 5更多还原
