摘要
以美国红枫的新鲜种子为材料,采用不同催芽方法进行发芽试验。结果表明:浸种24h能有效提高种子的发芽率,无论发芽率高低,各催芽方法的发芽高峰期相对集中,均为6d时间。其中置于光照培养箱中培养的基质培育法效果最好,发芽率最高提高了18.8%,光照培养箱、室温培养的各项指标与对照均有极显著差异。试验操作性方便、发芽率高,可大大提高美国红枫的推广力度。
With fresh seeds of Liquidambar styraciflua as materials,the germination experiment was conducted with different pregermination methods.The results showed that：the seeds soaking for 24 h could effectively enhance the germination rate,whatever germination rate,the germination peak of all pregermination methods was relatively concentrated,was 6 days.The best method was matrix culture method in illuminating incubator,the highest germination rate increased by 18.8%,the difference of index of the illuminating incubator treatment and normal temperature treatment was extremely significant with the control.Test operation was convenient,germination rate was high,which could greatly improve popularize strength of Liquidambar styraciflua.
