摘  要：
研究全国不同产地的蔓荆子种子寄藏真菌的情况,鉴定优势菌种并比较不同杀菌剂的处理效果,为蔓荆子种子播种前的预处理和种子真菌病害提供依据。采用离体平皿法对全国13个产地的蔓荆子种子进行带菌检测,分别用拌种法和浸种法对种子进行处理并测定7种杀菌剂对种子的消毒处理效果。结果表明:种子表面携带的优势菌群为青霉属(Penicillium spp)、根霉属(Rhizopus spp)、曲霉属(Aspergillus spp)、毛霉属(Mucor spp)、交链孢属(Alternaria spp)和镰孢霉属(Fusarium spp);种子内部寄藏的真菌主要为曲霉属、镰孢菌属和根霉属;不同品种的种子表面携带真菌种类差异较大,而种子内部寄藏的真菌种类差异不明显。多菌灵(carben-dazim)、多.福(carbendazim.fernasan)、甲基硫菌灵(thiophanate-methyl)、噁霜.锰锌(oxadixyl.mancozeb)对蔓荆子种子真菌均有显著性抑制和杀灭作用,但以噁霜.锰锌最优,甲霜.百菌清(metalaxyl.chlorothalo-nil)、百菌清(chlorothalonil)、福美双(fernasan)杀菌效果较差。多菌灵、甲基硫菌灵、多.福处理之后种子携带的真菌主要为根霉属、曲霉属。蔓荆子种子寄藏的优势真菌为曲霉属和镰刀菌属,噁霜.锰锌的杀菌效果可以达到96.7%以上。

摘  要：
To study the dominant seed-borne fungi in seeds from 13 different producing areas and compare the disinfection effect of several fungicides on seed-borne fungi in V.trifolia L.var.simplicifolia Cham.seed.Petri-dish testing was used to determine the external and internal seed-borne fungi and the disinfection effect of 7 fungicides with method of seed dressing and seed soaking.The results showed that Penicillium spp,Rhizopus spp,Aspergillus spp,Mucor spp,Alternaria spp,Fusarium spp were main seed-borne pathogens on the surface.Rhizopus spp,Aspergillus spp,Fusarium spp represented main seed-borne pathogens in-side.The fungi on the surface of seed expressed significantly difference among experimental varieties,but seed-borne fungi inside showed no difference.Carbendazim,carbendazim·Fernasan,th-iophanate-methyl,oxadixyl mancozeb provided better controls for seed-borne fungi than metalaxy·chlorothalonil,chlorothalonil,Fernasan.But the oxadixyl ·mancozeb was the best of all.Aspergillus spp,Fusarium spp were main seed-borne pathogens on the seed.The disinfection effect of oxadixyl·mancozeb was more than 96.7%.
