In order to find out the phosphate solubilizing bacteria which can improve or promote seed germination,radicle growth of flat bromegrass from Qiannan,the influence of the selected media to phosphate solubilizing bacteria growth and to the seed germination were detected.The test results of strain Br24 on the flat bromegrass seed germination under the treatments with different doses based on LB and PDA media showed that the improved LB medium was better than the PDA medium for the phosphate solubilizing bacteria growth.Meanwhile,the seeds under the treatments of liquid PDA culture had a better ratio and uniformity of seedling emergence compared with other processing.The best treatment for seed germination rate was to make the seeds soaked in liquid LB or PDA medium with strain Br24 for 6 minutes or to inoculate aforementioned bacterial suspension by the quantity not more than 2 mL and 1 mL respectively.The strain of Br24 has potential as phosphorus solubilizing inoculants and has good application effect and promising development in future.
