金荞麦提取物对植物病原菌的抑菌活性初探

Inhibition of Different Extracts of Fagopyrum dibotrysto Plant Pathogens

用金荞麦不同极性溶剂提取物对10种植物病原菌进行抑菌活性筛选研究,结果表明,金荞麦提取物对松赤枯病菌(Pestalotia funereal),玉米纹枯病菌(Rhizoctonia solani),油菜菌核病菌(Sclerotinia sclerotiorum),玉米弯胞杆菌[Curvularia Lunata(walk)Boed],小麦赤霉病菌[Gibberelle zeae(schw)],绿色木霉(Trichoderma viride)都有明显的抑制作用,但是对水稻稻瘟病菌(Pyricularia oryzae),黑曲霉(Aspergillus niger),柑橘绿霉(Penicillium digita-tum),镰刀菌(Fusariumsp.)却无抑制作用.

To screen the antifugal activity of the extracts fromFagopyrum dibotrys, the plant pathogen is used such as Pestalotia funereaL, Rhizoctonia solani , Sclerotinia sclerotiorum and Curvularia Lunata （walk） Boed et al. The result shows that extracts have strong antibacterial actionon Pestalotia funereal, Rhizoctonia solani , Sclerotinia sclerotiorum , Curvularia Lunata （walk） Boed, CribbereUe zeae （schw） and Trichoderma viride.
