摘要
通过对马铃薯晚疫病菌在7种不同培养基上及不同温度下的菌落生长和产孢情况的比较观察,对马铃薯晚疫病菌的培养条件进行筛选。结果表明,马铃薯晚疫病菌在黑麦培养基上的生长速度最快,产孢量最大,燕麦培养基次之,V_8培养基和PDA最差。在5~25℃温度范围内,马铃薯晚疫病菌均能产生孢子囊,但以20℃产生孢子囊数目最多且孢子囊较大。
A comparison was made among seven different solid mediums for culturing the Phytophthora infestans. The results showed that the growth rate of Phytophthora infestans and the number of sporangium on rye medium were best and oat medium second, but Vs medium and PDA were worst. A similar comparison was made among seven different temperatures. The result suggested that sporangia can be produced from 5℃ to 25℃, but optimal condition for Phytophthora infestans was 20℃.
