在开展小麦白粉病的有关研究中,需要长期保存菌种,传统的方法是将病菌接种在试管内种植的小麦幼苗上,发病后放在2—4℃有日光灯照明的冰箱中,能保存30天左右;Bennett等(1979)报道:将摘取的小麦幼苗叶片、接种发病后、置于3—5℃每天日照8小时的生长室内,该病菌可保存90多天。但一般单位因设备条件限制而难以应用。 In carrying out the research on wheat powdery mildew, long-term preservation of the need for bacteria, the traditional method is to inoculate the bacteria in vitro grown in wheat seedlings, after the incident on the 2-4 ℃ fluorescent lamp refrigerator, can save 30 Day; Bennett et al. (1979) reported that the leaves of wheat seedlings were inoculated and placed in the growth chamber at 3-5 ℃ for 8 hours per day. The bacteria could be stored for more than 90 days. However, the general unit due to equipment constraints and difficult to apply.
