摘　　要：采用固体培养和液体发酵相结合的方法,探索了培养真菌常用的7种碳源,10种氮源、7种无机盐和5种维生素对茶藨生柱锈重寄生菌拟盘多毛孢之一种(Pestalotiopsissp.)MM011菌株菌丝生长的影响。结果表明,多糖(可溶性淀粉、玉米粉)是该重寄生菌菌丝生长的最佳碳源;最佳氮源为有机氮中的黄豆粉、酵母浸膏和蛋白胨;最适无机盐为磷酸二氢钾和磷酸二氢钠;不同维生素对菌丝生长有一定影响,但作用不明显。The MM011 （Pestalotiopsis sp. ）-- mycoparasite of Cronartium ribicola was cultured in solid and liquid culture media using 7 hydrocarbons, 10 nitrogenous compounds,7 inorganic salts and 5 vitamins. It was found that polysaccharides（ solvable starch and maize flour） were favorable for mycelial growth, organic nitrogen （ protein peptone, yeast extracts, soy powder） was the optional nitrogen source, inorganic salts （ sodium phosphate and potassium phosphate） were more favorable for mycelial growth than others, mycelial growth varied in different growth factors, but the facilitation wasn＇t obvious.
