摘  要:
采用菌丝生长速率法,测定松针提取物对苦瓜枯萎病菌、小麦赤霉病菌、烟草赤星病菌和番茄早疫病菌4种植物病原真菌的抑菌活性。结果表明,松针提取物对4种植物病原真菌具有一定的抑菌活性,且在提取物质量浓度为20 mg/mL时,60%乙醇提取物抑菌效果较好,对4种植物病原菌抑制率均达到40%以上;提取时间1 h以上、提取温度70℃以上时,所得提取物抑菌效果较佳。

摘  要:
The research aimed to study the inhibition of Pinus elliottii against plant pathogenic fungi and by using the mycelium growth rates,the inhibition was measured.The results showed that Pinus elliottii had inhibitory components to plant pathogens.The 60% ethanol extracts had notable inhibiting effects on the different fungi tested at 20 mg/ mL.The inhibitory rates of the 60% ethanol extracts on Fusarium graminearum,Alternaria alternate,Alternaria solani,Fusarium oxysporum f.sp.mornordicae were all above 40%.Besides,over 1 hour extraction time and over 70 ℃ extraction temperature will get better antibacteriat effect.
