摘要
为探索提高石香薷发芽率的方法,实现石香薷的大规模人工栽培,以新鲜的石香薷种子为试验材料,采用正交试验L9(34)研究赤霉素(GA3)浸种浓度、浸种时间、层积温度和层积基质对种子发芽的影响。结果表明:GA3浸种浓度对种子发芽影响最大,层积温度次之,层积基质影响最小;并筛选出了各因素的最佳水平组合:GA3600.00 mg/L,浸种30 h,层积温度为变温(夜晚最低温16.2℃,白天最高温28℃),基质为河沙。对最佳因素组合进行验证表明,在最佳因素组合条件下,石香薷种子的发芽率达95.50%。
Fresh Mosla chinensis seeds were tested to study the effects of GA3 soaking concentration,soaking time,stratification temperature and laminated matrix on seed germination by using the orthogonal design to explore methods to enhance the germination rate of Mosla chinensis and achieve large-scale artificial cultivation.The results showed that the order of factors affecting seed germination was GA3 soaking concentration stratification temperature laminated matrix.The optimum condition for seed germination was 600.00 mg/L GA3,soaking 30 h,variable temperature（the lowest temperature during night was 16.2℃,the highest temperature during the day was 28℃）,the matrix was sand,and the germination rate of Mosla chinensis seeds could reach 95.50% under optimized conditions.
