| 摘 要： | 枯草芽孢菌株（Bacillus subtilis）TL2能产生多种外分泌抗菌蛋白,抑制茶轮斑病菌（Pestallozzia theae）的菌丝生长及其分生孢子的形成和萌发。另外,菌株TL2通过改变茶树体内活性氧代谢相关酶系如SOD等的活性,以调节茶树受轮斑病菌侵染后活性氧的代谢平衡,同时诱导茶树产生抗性酶系如PAL和β-1,3-葡聚糖酶,以限制茶树轮斑病菌的扩展。

| Abstract: | The antifungal proteins secreted by Bacillus subtilis strain TL2 were tested and showed a good inhibitive effect on the mycelial growth and the conidia germination of Pestalotiopsis theae. It was also found that when strain TL2 was inoculated, the SOD activity in tea plant were obviously changed to depress the generating speed of superoxide anion in tea plant, also the PAL activity and β-1,3-glucanases activity in tea plant were quickly increased to restrain the expansion of P. theae. |
