摘要

在豆科根瘤菌经细菌处理后的植物上,观察了恶臭假单胞菌和氧化锌纳米颗粒(ZnO NPs)单独或联合施用对治疗嗜烟假单胞菌和丁香假单胞菌的效果。豌豆(Pisum sativum)。无头棘球绦虫与丁香棘球绦虫的接种。与未接种对照相比,Pisi单独接种和两者一起接种均降低了植株生长、叶绿素和类胡萝卜素含量。单独或联合使用腐皮假单胞菌和ZnO NPs 0.10 ml−1(叶面喷雾/种子启动)可显著提高接种病原体的植株的生长、叶绿素和类胡萝卜素。氧化锌NPs喷种在促进植物生长、叶绿素和类胡萝卜素含量方面优于NPs叶面喷种。在促进植株生长、提高叶绿素含量和类胡萝卜素含量方面,腐殖菌加NPs种子灌浆比叶面喷施效果更好。豆科致病菌的杀菌效果较好,且腐殖酸致病菌的根瘤效果好于氧化锌致病菌。两种试验病原菌对根结瘤均有不利影响。以氧化锌NPs为引种剂处理腐殖酸线虫时,病害指数、虫蛀率和线虫数量均显著降低。

Effects of Pseudomonas putida and zinc oxide nanoparticles (ZnO NPs) with Rhizobium leguminosarum on the management of Meloidogyne incognita and Pseudomonas syringae pv. pisi on pea
Effects of Pseudomonas putida and zinc oxide nanoparticles (ZnO NPs) alone and in combination was observed in plants grown with bacterized seeds with Rhizobium leguminosarum for the management of Meloidogyne incognita and Pseudomonas syringae pv. pisi on pea (Pisum sativum). Inoculation of M. incognita and P. syringae pv. pisi alone and both together reduced plant growth, chlorophyll and carotenoid content over uninoculated control. Use of P. putida and ZnO NPs 0.10 ml−1 (foliar spray/seed priming) alone and in combination resulted in a significant increase in plant growth, chlorophyll, and carotenoid in pathogen-inoculated plants. Seed priming with ZnO NPs was better than NPs foliar spray in increasing plant growth, chlorophyll and carotenoid content of plants with pathogens. Use of P. putida plus NPs seed priming was better than its use with foliar spray in increasing plant growth, chlorophyll, and carotenoid. Bacterization with R. leguminosarum caused sufficient root nodulation and nodulation was better in plants with P. putida than in plants with ZnO NPs. Both test pathogens had adverse effect on root nodulation. Blight disease indices, galling, and nematode population were also greatly reduced when P. putida was used with ZnO NPs seed priming.
