BHT对6种植物病原真菌抑制作用的研究
Study on the Inhibition Effect of BHT on Six Kinds of Plant Pathogenic Fungi
摘要
Abstract
In order to measure the antibacrerial activity of BHT, the inhibition of mycelia growth and spore germination for six plant pathogenic fungi were measured by the growth rate and pendent drop methods in the test. The results showed that there was a certain inhibition effect of BHT against six pathogenic fungi, with EC50 of inhibiting mycelia growrh between 129. 18 to 1113. 85 mg ·L-1. The effect of EC50 was most ohvious against Fusarium graminearum when the effective concentration was 129. 18 mg · L-1 ; EC50 of inhibiting spore germination were between 160. 51～356. 03 mg · L-1 , and there was a high inhibition rate on Alternaria triticina. when EC50 was 160. 51 mg ·L-1.Meanwhile, the inhibition of mycelia growth of BHT and four common drugs to Fusarium graminearum and Alternaria solani were compared. and the results showed that the difference between EC50 of two kinds of pathogenic fungi above was relatively minor.关键词
