Plant growth promoting rhizobacteria (PGPR) are beneficial rhizobacteria which enhance plant growth as well as the productivity by a variety of mechanisms PGPR were isolated from the rhizosphere region of som plants (Machilus bombycina King) maintained at the Central Muga Eri Research and Training Institute, Lahdoigarh, Jorhat. A bacterial based bioformulation was prepared and sprayed over the experimental crops including tomato (Solanum lycopersicum), cauliflower (Brassica oleracea var botrytis), chili (Capsicum annuum) and brinjal (Solanum melongena). Biochemical analysis was done on these PGPR treated crops as well as the untreated crops. The bioformulations prepared from Bacillus cereus (MTCC 8297), Pseudomonas rhodesiae (MTCC 8299) and Pseudomonas rhodesiae (MTCC 8300) was found to be the most effective in increasing the shoot height, number of leaves, early fruiting and total biomass content of the plants after treatment.
植物促生根际细菌（PGPR）是一类有益的根际细菌，它们通过多种机制促进植物生长并提高生产力。从位于乔哈特市拉多伊加尔的中央穆加柞蚕研究与培训研究所培育的某些植物（润楠）根际区域分离出了PGPR。制备了一种基于细菌的生物制剂，并将其喷洒在包括番茄（番茄）、花椰菜（甘蓝变种花椰菜）、辣椒（辣椒）和茄子（茄子）在内的实验作物上。对这些经PGPR处理的作物以及未处理的作物进行了生化分析。发现由蜡样芽孢杆菌（MTCC 8297）、罗得西亚假单胞菌（MTCC 8299）和罗得西亚假单胞菌（MTCC 8300）制备的生物制剂在处理后对增加植物的茎高、叶片数量、早期结果和总生物量含量最为有效。
