广西莪术(Curcuma kwangsiensis S.G.Lee et C.F.Liang)为姜科姜黄属植物.通过抑菌实验和电镜技术等方法测定研究了广西莪术油对6种植物病原真菌的抑制作用,结果表明:广西莪术油具有较强的抗真菌活性,对植物病原真菌孢子萌发和菌丝生长...广西莪术(Curcuma kwangsiensis S.G.Lee et C.F.Liang)为姜科姜黄属植物.通过抑菌实验和电镜技术等方法测定研究了广西莪术油对6种植物病原真菌的抑制作用,结果表明:广西莪术油具有较强的抗真菌活性,对植物病原真菌孢子萌发和菌丝生长均有显著的抑制作用.最低抑制浓度(MIC)的莪术油6.25mL/L对植物病原真菌孢子萌发和菌丝生长均有显著的抑制作用.半抑制率IC50表明广西莪术油对松赤枯病菌的抑制作用最强,最弱的是小麦赤霉病菌.电镜下观察菌丝的横切面表明,处理菌丝的细胞壁消失,原生质解体.研究结果表明广西莪术具有开发为生物农药的潜力.展开更多
利用简单重复序列分子标记技术对广西莪术(Curcuma kwangsiensis S.G.Lee et C.F.Liang)种质资源进行了遗传多样性分析。结果表明,筛选出的14对引物在50份广西莪术种质资源中共扩增出78个条带,其中60条呈现多态性,多态性比率为76.92%,...利用简单重复序列分子标记技术对广西莪术(Curcuma kwangsiensis S.G.Lee et C.F.Liang)种质资源进行了遗传多样性分析。结果表明,筛选出的14对引物在50份广西莪术种质资源中共扩增出78个条带,其中60条呈现多态性,多态性比率为76.92%,反映出广西莪术种质资源在分子水平上存在较大的差异;广西莪术不同种质资源间的差异主要由遗传因素决定,但也与环境因素有关。聚类结果将50份广西莪术种质资源分成2大类,揭示了它们之间的遗传差异,这为今后广西莪术优良品种的选育提供了依据。展开更多
