| 摘 要： | 描述了马铃薯晚疫病菌卵孢子萌发的方式并研究了菌株组合、卵孢子形成时间、在琼脂培养基上培养时间及光照对卵孢子萌发的影响,结果表明不同菌株组合卵孢子萌发率为0—7.2%,对峙培养20天后形成的卵孢子的萌发率最高达8.7%,在琼脂培养基上培养25-30d 萌发率最高达11.4%,卵孢子形成时黑暗及在琼脂培养基上萌发时光照萌发率最高达11.8%。

| Abstract: | Mode of oospores germination of Phytophthora infestans was described. Effects of isolate combinations, time of oospores formation, incubation time on the agar media and light on oospores germination were studied. The results were as follows: Germination rate of oospores produced by different isolate combinations was from 0 to 7.2%. Germination rate of oospores formed was 8.7% when two isolates of different mating types were cultivated for 20 days and their germination rate was 11.4% when oospores were incubated for 25-30 d in the agar media. The highest germination rate of oospores produced in the darkness and incubated under the light in the agar media was 11.8%. |
