摘要
为筛选植物生长调节剂中具有潜在抑菌活性的化合物,采用菌丝生长速率法分别测定了10种植物生长调节剂对番茄灰霉病菌和小麦赤霉病菌的室内抑菌活性。结果表明,10种化合物对番茄灰霉病菌和小麦赤霉病菌均表现出不同程度的毒力。化合物萘乙酸钠对小麦赤霉病菌的抑菌活性与对照■霉灵相当,复硝酚钠、萘乙酸钠、吲哚丁酸钾、赤霉酸、吲哚乙酸、吲哚丁酸对番茄灰霉病菌均表现出较好的抑菌活性。初步拟定将这6种化合物作为下一步开发抑菌化合物的先导。
In order to discover modifiable lead compounds with antifungal activities from plant growth regulators.Ten kinds of plant growth regulator compounds were prepared and bio-evaluated for their antifungal activities against Botrytis cinerea and Fusarium graminearum by mycelium growth rate method in vitro.The results indicated that the ten kinds of plant growth regulator compounds show different degree of antifungal activity for two kinds of plant pathogenic fungi.The antibacterial activity of sodium 1-naphthal acitic acid on Fusarium graminearum was similar to the activity of hymexazol.Sodium nitrophenolate,sodium 1-naphthal acitic acid,potassium 4-indol-3-ylbutyric acid,gibberellic acid,forchlorfenuron,Kinetin,indol-3-ylacetic acid,4-indol-3-ylbutyric acid showed good antifungal activities against Botrytis cinerea.
