摘要
本研究旨在调查粉红色素兼性甲基营养体(PPFMs)叶面喷施对提高辣椒作物生长参数的潜在影响。实验室和盆栽研究在阿南德农业大学农业微生物学系进行。PPFMs 分离自茄科作物(辣椒、布里雅尔、马铃薯、番茄和烟草)的叶球,根据其甲醇消耗和促进植物生长的特性,从 30 个分离物中选出了 5 个。在研究了这些分离物的兼容性后,组成了分离物联合体(Methylobacterium populi AAU PPFM C-7、M. radiotolerans AAU PPFM C-17、M. populi AAU PPFM C-19、M. populi AAU PPFM T-2 和 M. radiotolerans B-2)。盆栽研究是在网室中对辣椒作物进行的,采用完全随机设计,四次重复。研究结果表明,PPFMs 复合菌群对辣椒生长参数(即芽长、根长、芽重、根重、每株分枝数)有显著影响,这可能是 PPFMs 植物生长促进特性的结果。
Development of Pink Pigmented Facultative Methylotrophs’ (PPFMs) Consortium Formulation and Its Efficacy on Chilli (Capsicum annuum)
This research aims to investigate the potential effect of Pink Pigmented Facultative Methylotrophs (PPFMs) as foliar application to enhance growth parameters of chiili crop. The laboratory and pot studies were conducted at Department of Agricultural Microbiology, Anand Agricultural University, Anand. The PPFMs were isolated from the phyllosphere of solanaceous crop (Chilli, Brinjal, Potato, Tomato and Tobacco) and five out of thirty isolates were selected based on their methanol consuming and plant growth promoting traits. Consortium of isolates (Methylobacterium populi AAU PPFM C-7, M. radiotolerans AAU PPFM C-17, M. populi AAU PPFM C-19, M. populi AAU PPFM T-2 and M. radiotolerans B-2) were prepared after studying their compatibility. Pot study was laid out in net house using completely randomized design with four replications on Chilli crop. The results of the study showed significant effect of PPFMs consortium on growth parameters of chilli (viz. shoot length, root length, shoot weight, root weight, number of branches per plant) that could be result of the plant growth promoting traits of PPFMs.
