摘要：

测定竹焦油对14种植物病原真菌的抑制效果，研究竹焦油对水稻纹枯病菌的抑制作用，用GC/MS法分离鉴定竹焦油的主要成分。结果表明: 竹焦油对供试菌的菌丝生长、孢子萌发均有不同程度的抑制效果，其中对十字花科蔬菜菌核病菌与水稻纹枯病菌的菌丝生长、稻瘟病菌的孢子萌发有较强的抑制作用。竹焦油具有使水稻纹枯病菌的菌丝形态异常、氧呼吸减弱的作用，对水稻纹枯病有一定的防治效果。成分分析结果显示: 竹焦油中酚类物质相对含量高达72.491%。

Abstract:

The inhibitory activities of bamboo (Phyllostachys pubescens) tar to 14 varieties of plant pathogen fungi were determined. The inhibitory effects of bamboo-based tar on Rhizoctonia solani were studied, and the main components of the bamboo bar were separated and identified by GC/MS analysis. The result showed that the bamboo-based tar had various inhibitory activities on mycelia growth and spore germination of the tested fungi, of which the inhibitory effects on mycelia growth of Sclerotinia sclerotiorum and R. solani, on spore germination of Pyricularia grisea were the best. The bamboo-based tar brought about the mycelia ofR.solani deformation and its respiration decline, and had some control effect on rice sheath blight. The GC/ MS analysis showed that the relative content of phenolic compounds in the bar amounted to 72.491%.
