| 英文摘要 | Replacing agrochemicals with plant growth promoting bacteria (PGPB) may offset some of the environmental impacts of food production. The objectives of this study were to (1) isolate and characterize bacterial strains from tomato rhizosphere, including root, shoot and leaf, (2) select and identify the most promising PGPB strains, (3) verify the phytostimulatory activity and mineral uptake potential of selected strains. Bacterial strains isolated from tomato rhizosphere, were screened for phosphorous (P) solubilization, production of indole acetic acid (IAA), amylase activity, antibiotic resistance, and quick test strip (QTS) for biochemical characterization. The tested strains, positive for all five of these assays were selected for molecular identification and subjected to greenhouse growth trails with tomato and mung bean. Two strains were selected and identified as Bacillus cereus (B. cereus) isolated from rhizosphere and Klebsiella variicola (K. variicola) isolated from root endosphere using 16s rRNA sequences. Both strains produced IAA, gibberellic acid (GA3) and kinetin, however B. cereus showed potential GA3 and IAA production as compared to K. variicola. In tomato, only one growth variable (shoot length) was increased over the control by one of the selected bacterial strains (B. cereus). In mung bean, inoculation with either strain B. cereus or K. variicola increased shoot length and dry weight. Moreover, our results showed that the use of PGPB significantly increased plant growth and Fe, Zn, Ca, Mg, Cu, Na and K contents of plants. It seems that evaluated strains had a higher ability in boosting plant growth and higher yield. |
