摘　　要：真菌类杂菌是影响食用菌安全生产的重要因素之一。以25株黄伞(Pholiota adiposa)为供试材料,研究其抗杂性、栽培菌棒上真菌类杂菌的种类及多样性。结果显示,不同黄伞菌株的抗杂性存在差异,菌株JZB216061和菌株JZB216016的抗杂性较强,具有开发潜力;从25株黄伞的污染栽培菌棒上共分离得到65株真菌类杂菌,其中青霉(Penicillum spp.)、曲霉(Aspergillus spp.)和木霉(Trichoderma spp.)是污染黄伞栽培菌棒中的主要真菌类杂菌,且青霉污染最为普遍;不同真菌类杂菌对黄伞栽培菌棒的污染能力存在较大差异,桔青霉(Penicillum citrinum),在黄伞栽培菌棒中的污染最为普遍,可污染10个不同黄伞菌株的栽培菌棒,在栽培过程中应重点防护。研究结果将为黄伞栽培菌棒上真菌类杂菌的防治、黄伞的安全生产及种质资源的评价提供数据支撑。Contaminated fungi are one of the important factors in the safe production of edible fungi. Twenty-five strains of Pholiota adiposa were used as test materials to study their resistance to contaminated fungi and diversity of contamination fungi on the artificial bed-logs. The results showed that the resistance of different strains of P. adiposa to contamination fungi were significant different, JZB216061 and JZB216016 had stronger resistance to contamination fungi. Sixty-five contamination fungi strains were isolated from the twenty-five P. adiposa strains, which were dominanted by Penicillium spp., Aspergillus spp. and Trichoderma spp., and contaminations from Penicillium spp. were the most common. A broad diversity in aggressiveness among different contaminated fungi to P. adipose were observed. Contamination from Penicillum citrinum was the most common in the artificial bed-logs of P. adiposa, which can pollute the artificial bed-logs from ten different strains of P. adipose, deserving close attention in the production. The results will provide data support for the control of contamination fungi, the safe production of P.adipose and evaluation of its germplasm resources.
