摘要:
为了检测棘孢木霉T12对立枯丝核菌的生防效果,测定了T12对立枯丝核菌RS02菌株竞争性抑制作用,T12挥发性代谢物对RS02菌核萌发和菌丝生长的影响,T12的发酵液对RS02菌核萌发、菌丝干质量和侵染相关酶活力的影响。结果显示,培养4d的T12通过空间竞争对RS02生长产生抑制,抑制率达78.7%;T12产生的挥发性物质对菌核萌发和菌丝生长抑制率分别为10.3%、12.2%;大于10%浓度T12发酵液对菌核萌发、菌丝干质量均表现出显著或明显的抑制效果,50%浓度发酵液对菌核萌发、菌丝干质量的抑制率分别为65.7%、88.2%;培养5 d,10%、30%、50%浓度发酵液处理的RS02纤维素酶活力分别降低了17.4%、55.0%、76.8%,果胶酶活力分别降低了21.8%、53.9、69.5%。综合试验结果可知,棘孢木霉T12能够显著抑制立枯丝核菌的生长并降低其侵染能力。
