Effect of Stratification and GA_3 Joint Treatment on the Germination of Mosla chinensis Maxim. Seed

摘要(Abstract):

[Objective]To study the effect of stratification and gibberellin(GA3) joint treatment on the germination of Mosla chinensis Maxim.seeds,so as to provide basis for the artificial cultivation of Mosla chinensis Maxim.in large scale.[Method] Treated at 5-10,15,20 ℃ and laminated with river sand,sawdust and filter paper respectively,then the seeds of Mosla chinensis Maxim.were soaked in 400,600,800 mg/L GA3 solution for 18,24,30 h respectively and then subjected to germination test in 25 ℃ germinator.[Result] The optimal germination conditions were determined to be germination temperature of 25 ℃,stratification treated under 5-10 ℃,GA3 concentration of 800 mg/L,soaking duration of 30 h.Under the above conditions,the germination rate of Mosla chinensis Maxim.seeds reached as high as 96.25%.[Conclusion] The germination rate of Mosla chinensis Maxim.seeds can be promoted significantly by stratification and GA3 joint treatment,which would lay foundation for the artificial cultivation of Mosla chinensis Maxim.in large scale.
