实践证明:采用试管小苗培养保存小麦白粉菌,具有接种、培养、保存方便,保存时间较长,不易污染等优点。用灭菌NPK琼脂培养无菌试管小苗,2～3叶期接种白粉菌,待产生分生孢子后放入2～11℃冰箱内,每天用两支8瓦日光灯照射12小时,可保存一月以上转管。在自然光照的适温条件下,或气温较低时,一般可保存至两月转管,最长可达三月左右。 Practice has proved that: the use of tube seedling culture save powdery mildew, with inoculation, culture, easy to save, save a long time, not easy to pollution and so on. Inoculated with sterilized NPK agar sterile tube seedlings, 2 to 3 leaf stage inoculation powdery mildew, to be generated after the conidia into the refrigerator 2 ~ 11 ℃, day with two 8-watt fluorescent lamp irradiation for 12 hours, can be stored in January Transfer to the above. In the natural light of the temperature conditions, or when the temperature is low, the general can be saved to two months tube, the longest up to about March.
