| Abstract: | Objective] The study was to find a suitable approach for germination treatment of the seeds of Dosacus asper Wall..Method] The ordinary germination in petri dish was conducted to study the influences with different concentrations of gibberellins on the germinating character of the seeds of Dosacus asper Wall..Result] Treatment in GA3 can promote the germination of the seeds of Dosacus asper Wall..When the seed of Dosacus asper Wall.was soaked with 300 mg/L concentration of GA3 in 12-24 h,the effect of accelerating germination was good under 20-25 ℃ and meanwhile the germination rate and the germination energy respectively will increase by 76.3% and 59%.Conclusion] The article can provide some theoretical basis and technical references for standardized cultivation of Dosacus asper Wall.seeds. |
