摘要 研究了储藏片烟霉菌的营养生长、分生孢子萌发和芽管伸长的温湿度范围,并在液体培养基中测定了温度对菌丝生长的影响。结果表明:菌丝体营养生长的温度范围为10~35℃;20~30℃范围有利于分生孢子萌发和芽管伸长,芽管伸长以30℃最佳,而葡枝根霉为25~40℃,且分生孢子萌发以35℃最佳。液体培养中,曲霉菌和青霉菌温度为25℃时菌丝生长量最大,毛霉菌和根霉菌分别为10℃和35℃。曲霉菌在相对湿度为70%~75%时菌丝生长速率最大,而青霉菌和毛霉菌在相对湿度为90%,葡枝根霉菌为85%。分生孢子的萌发对湿度要求严格,在相对湿度>60%时霉菌孢子才能萌发,且在自由水和有水膜的情况下,萌发的更好。 The effect of temperature and humidity on the growing rate of mildew hyphal, conidia germination and germ tube elongation in stored tobacco was studied. The results reported was as follows: in the temperature from 10 ℃ to 35 ℃ the hyphal could survive. The temperature from 20 ℃ to 30℃ was beneficial for conidia germination and germ tube elongation. The germ tube grew at 30℃ more than that of other temperatures. Rhizopus growth was in 25 ℃ to 40℃ and conidia germination was optimum at 35 ℃. While mildew was incubated in the liquid culture medium at 25 ℃, the dry weight of AspergiUus and Penicillum hyphal was heaviest and in the range from 10℃ and 35 ℃ Mucor and Rhizopus hyphal dry weight was the heaviest, respectively. When the relative humidity was at 70 %-75 %, the hyphal grew the best; but PeniciUum and Mucor at 90 % and Rhizopus at 85 %. Conidia germination requested high humidity condition, when the relative humidity was more than 60 %, conidia germinated better in free water than in water film.
