采用统计试验设计，研究了水分活度（a（w））和温度对普通青霉（CPA）和黄曲霉（CPA和黄曲霉毒素AF）在玉米上产毒的联合影响。方差分析表明，这些因素和霉菌毒素的生产之间的高度显着的相互作用（P小于或等于0.001）。产CPA的最低a（w）/温度分别为2264 ng g（-1）、709 ng g（-1）和100 ng g（-1）。黄曲霉的产量为0.90 a（w）/30 ℃，而地木耳的产量最高，为7678 ng g（-1），白曲霉为1876 ng g（-1）。flavus）在0.98 a（w）/20 ℃下产生。在0.90 a（w）/20 ℃时产生的AF最少（411 ng g（-1）），在0.98 a（w）/30 ℃时产生的AF最多（3096 ng g（-1））。
The combined effects of water activity (a(w)) and temperature on mycotoxin production by Penicilium commune (cyclopiazonic acid - CPA) and Aspergillus flavus (CPA and aflatoxins - AF) were studied on maize over a 14-day period using a statistical experimental design. Analysis of variance showed a highly significant interaction (P less than or equal to 0.001) between these factors and mycotoxin production. The minimum a(w)/temperature for CPA production (2264 ng g(-1) P. commune, 709 ng g(-1) A. flavus) was 0.90 a(w)/30 degrees C while greatest production (7678 ng g(-1) P. commune, 1876 ng g(-1) A. flavus) was produced at 0.98 a(w)/20 degrees C. Least AF (411 ng g(-1)) was produced at 0.90 a(w)/20 degrees C and most (3096 ng g(-1)) at 0.98 a(w)/30 degrees C.
