通过对玉米瘤黑粉病菌冬孢子生物学特性的研究，明确了该病菌冬孢子萌发的最适温度为２５～３０℃，最适ｐＨ值为３～５，在自然光周期条件下萌发较好，以及适宜的营养培养液和浓度，适宜萌发的相对湿度。
Through the study on the biological characteristics of the teliospore of Y. tritici, it was clarified that the optimum temperature of the spore germination was 25-30 ℃ and the optimum pH value was 3-5. The germination was better under the natural photoperiod, As well as the appropriate nutrient broth and concentration, appropriate germination relative humidity.
