近年来,国内外很多人对真菌孢子萌发进行了研究,但对分布广、引致甜菜黑脚病、蛇眼病的p·betae知道的较少,为了明确它的生理生态状况,为病害防治和抗病性鉴定提供依据,作者对p·betae孢子萌发进行了研究。试验材料和方法供试菌种从甜菜蛇眼病病叶分离后,经接种证明了它的致病性。萌发用培养皿法:先用重蒸馏水,把在马铃薯洋菜培养基上培养11～20天的
In recent years, many people at home and abroad have carried out research on the spore germination of fungi, but they have little knowledge about the distribution of p betae, which leads to the beet blackfoot disease and snake eye disease. In order to clarify its physiological and ecological status, The basis for the identification of the disease, the author of beta betae spore germination were studied. Test materials and methods Species tested after separation from the beet snake eye diseases, vaccination proved its pathogenicity. Petri dish germination method: first with distilled water, the culture of potato agar medium for 11 to 20 days
