摘要
针对花楸种子通过3种层积方法(持续低温、低温-中温、低温-高温)、不同赤霉素浓度处理研究其对花楸种子发芽的影响。结果表明:经过100mg/L GA处理后采用35天0~5℃层积后转入5~15℃层积的方法,其平均发芽时间最短,62.3天即可发芽,并且绝对发芽率最高,达到69.13%。
According to the Sorbus pohuashanensis seed by three stratification method （continuous low temperature, low temperature, medium temperature, low temperature high temperature） and Gibberellin on Seed Germination of the influence of the. The results showed that after 100ppm GA treatment, the average germination time was the shortest and the germination rate was the highest in 62. 3 days, and the absolute germination rate was the highest, which reached to 69.13%, which was transferred to 5-15℃ layer after days of 0-5℃. In addition, the seed sowing experiments.
