摘  要:
[目的]研究层积联合赤霉素(GA3)处理对石香薷种子萌发的影响,为石香薷的大规模人工栽培奠定基础。[方法]将石香薷种子分别在5~10℃变温和15、20℃温度下用河沙、木屑及滤纸作基质层积,分别浸泡在400、600、800 mg/L的GA3中18、24、30 h,置于25℃种子发芽箱中发芽。[结果]发芽温度为25℃,在5~10℃变温下用河沙层积处理后用800 mg/LGA3浸泡石香薷种子30 h,种子平均发芽率最高,为96.25%。[结论]层积处理后用GA浸种能明显促进石香薷种子发芽,这为石香薷的大规模人工栽培奠定了基础。

摘  要:
[Objective] To study effect of stratification coupled with GA3 treatment on germination of Mosla chinensis Maxim.seed,so as to provide basis for the large-scale artificial cultivation of Mosla chinensis Maxim..[Method] Treated at 5-10,15 and 20 ℃ and stratified with river sand,sawdust and filter paper respectively,Mosla chinensis Maxim.seeds were soaked in 400,600 and 800 mg/L GA3 for 18,24 and 30 h,respectively,and then were subjected to germination test in 25 ℃ germination box.[Result] The optimal germination conditions were determined to be germination temperature of 25 ℃,poikilothermic treatment of 5-10 ℃,stratification matrix of river sand,GA3 concentration of 800 mg/L and soaking duration of 30 h.Under the optimal treatment,the germination rate of Mosla chinensis Maxim.seeds reached as high as 96.25%.[Conclusion] The germination rate of Mosla chinensis Maxim.seeds are promoted largely,which provides the basis for large-scale artificial cultivation of Mosla chinensis Maxim..
