| Abstract: |
| The germination capacity of the seeds was obviously promoted after five herbage seeds soared with natural brassinolide.Compared with the control,the germination rate of Medicago sativa seeds was increased by 32.2% after using 0.01 mg/L natural brassinolide treatment,and mean germination days of the seeds was cut down by 1.4 day.After Rumex seeds were treated with 0.01 mg/L natural brassinolide,the germination rate of the seeds was increased by 27.8%,and mean germination days of the seeds was cut down by 0.8 day after seeds treated with 0.05 mg/L natural brassinolide.The germination rate of Puna chicory seeds increased by 28.9% after the seeds treated with 0.03 mg/L natural brassinolide,and mean germination days of the seeds was cut down by 0.3 day.After Silphium perfoliatum seeds treated with 0.4 mg/L natural brassinolide,the germination rate of the seeds was increased by 26.7%,and mean germination days of the seeds was cut down by 1.2 day.After Coronilla varia seeds treated with 0.03 mg/L natural brassinolide,the germination rate of the seeds was increased by 23.3%,and mean germination days of the seeds was cut down by 0.8 day after seeds treated with 0.05 mg/L natural brassinolide.0.05 mg/L natural brassinolide was the most suitable for the elongation of Medicago sativa radicle and hypocotyls,0.07 mg/L was the best for the elongation of Rumex radicle and hypocotyls,and 0.03 mg/L was the most suitable for the elongation of Puna chicory and Coronilla varia radicle and hypocotyls,0.4 mg/L natural brassinolide was the most suitable for the elongation of Silphium perfoliatum radicle and hypocotyls. |
