摘要: [目的]通过从阿魏根际中筛选分离获得具有ACC脱氨酶活性的PGPR菌株,研究其对加工番茄种子发芽及种子酶活性的影响.[方法]通过不同时间、不同浓度PGPR菌液对新疆加工番茄里格尔(87-5)浸种处理,研究其对新疆加工番茄里格尔种子萌发特性的影响.[结果]菌液A25处理番茄种子在OD600 nm处吸光值0.5、浸种4h,发芽势最好,发芽势为(60±4.0);,种子α-淀粉酶活力值是4.454 7 mg/(g·5 min);菌液T129处理番茄种子在OD600 nm处吸光值0.25、浸种4h,发芽势最好,发芽势为(62±2.0);,种子d-淀粉酶活力值为3.570 mg/(g·5min).[结论]经PGPR菌液处理里格尔后,种子淀粉酶活性随着时间和浓度的增加出现峰值后递减.
