目的为百合病害防治以及国家种子种苗标准平台的建立提供基础资料。方法采用洗涤法与PDA培养法分别对采自吉林、甘肃、湖南、江西、安徽、江苏6省33份百合鳞茎样品进行表面及内部所带真菌检验。结果从百合鳞茎表面和内部分别分离出12和10个属的真菌。优势菌均为青霉菌(penicilliumsp.)、镰刀菌(Fusariumsp.)、木霉(Trichodermasp.)、黑根霉(Rhizopussp.)、毛霉属(Mucorsp.)。百合鳞茎表面孢子负荷量以江苏宜兴新庄镇官渎村样品最小,为0.32×106个/粒,而江西万载白水乡白水村样品4的孢子负荷量最大,为7.24×106个/粒。结论百合鳞茎表面及内部带真菌数量较多,且种类较杂,因此在栽培、储藏、运输中应对优势真菌进行健康检查,并采取必要的防治措施。
The purpose is to provide the basic information for lily disease prevention and control as well as the establishment of the national seed seedling standard platform. Methods 33 samples of lily bulbs collected from 6 provinces of Jilin, Gansu, Hunan, Jiangxi, Anhui and Jiangsu provinces were tested for fungi on the surface and inside by means of washing method and PDA culture method respectively. Results 12 and 10 genera of fungi were isolated from the surface and inside of lily bulbs respectively. The dominant bacteria are Penicillium sp., Fusarium sp., Trichoderma spp., Rhizopus spp., Mucorsp. The spore load of lily bulbs on the surface was the lowest in Guandu Village, Xinzhuang Town, Yixing City, Jiangsu Province, 0.32 × 106 grains / grain, while the spore load of Baishui Village, Baishui Township, Wanzai County, Jiangxi Province was the highest, which was 7.24 × 106 grains / grain. Conclusion There are many fungi on the surface and inside of lily bulbs, and the types are more complex. Therefore, the dominant fungi should be checked healthily in cultivation, storage and transportation, and the necessary control measures should be taken.
