【摘要】 以小麦赤霉病菌,辣椒疫霉病菌,葡萄黑曲霉病菌,苹果炭疽病和玉米大斑病菌为实验菌种,采用生长速率法测定月腺大戟根部提取物对病原菌菌丝生长的抑制作用。结果表明,月腺大戟根部提取物对5种农作物常见病菌都有抑制作用,其中对3种病原菌(小麦赤霉病菌、苹果炭疽病菌、玉米大斑病菌)的菌丝抑制作用强烈;乙醇相提取物对病原菌抑制作用比水相提取物的抑制活性强。更多还原

【Abstract】 Taking Gibberella zeae,Phytophthora capsici,Aspergillus niger,Colletorichum gloeosporioides,Exserohilum turcicum as the experimental bacterial germ to study antifungal activity of the root extracts from Euphorbia ebracteolata through the use of the grow speed law.The results showed that root extracts of E.ebracteolata had inhibition against five common crop germs,and had strong antifungal activities against three tested fungi(Gibberella zeae,Colletorichum gloeosporioides,Exserohilum turcicum).Root ethanol extracts had better antifungal activities than water extracts.更多还原
