1.小麦秆枯病近年来在河北和山西的个別地区發生普遍,最高發病率达到45%,平均發病率在定县西建阳村和太谷部分村庄达到3%和5.5%。2.小麦秆枯病菌子囊孢子必需要有小麦組織的刺激始能萌發。在缺乏刺激物时,萌發率一般在1%以下,加入刺激物后,萌發率可以提高数十倍. 3.小麦秆枯病菌子囊孢子有一部分并不需要長期休眠,根据本試驗結果,約有10—20%左右的孢子在小麦收获后的一个月內即可萌發。大部分孢子后熟期相当長。低温可以加速孢子的成熟,但經过低温作用的孢子如無小麦組織的刺激同样不能萌發。
1. Wheat stem blight has been endemic to some areas of Hebei and Shanxi in recent years with the highest incidence of 45%. The average incidence rate is 3% and 5.5% in the villages of Xijianyang and Taigu in Dingxian County. 2. Wheat straw blight Ascospore must have the stimulation of wheat tissue to germinate. In the absence of irritants, the germination rate is generally below 1%, after adding stimuli, the germination rate can be increased by several times. 3. Wheat stalk blight Aspergillospores do not need some long-term dormancy, according to the test results, about About 10-20% of the spores germinate within one month after the wheat is harvested. Most of the spores after ripening quite long. Low temperature can accelerate the spore maturation, but the spore through the role of low temperature, such as wheat-free stimulation can not germinate.
