在色季拉山野生花楸资源调查的基础上,进行了野生花楸的种子繁育试验,初步分析了野生花楸的种子萌发特性。试验结果表明:野生花楸种子存在生理后熟的现象,不宜在当年秋季播种育苗;种子经过冬季120d的露地沙藏层积后,能够促进其完成后熟并有效解除休眠,使发芽时间一致,出苗整齐。春季发芽试验结果表明,野生花楸种子发芽率较低,不同处理方式之间的发芽率差异显著,其中,以60℃温水浸种48h后,再经过10d室外昼夜变温作用的处理方式发芽效果最佳,能达到48%。
Based on the investigation of the wild Sorbus Linn. Resources in Sejila Mountain, the seed breeding experiments of Sorbus aucuparia were conducted, and the seed germination characteristics of Sorbus aucuparia were preliminarily analyzed. The results showed that the seeds of wild Sorbus roxburghii had the phenomenon of physiological after-ripening and should not be sown in the autumn of the same year. After the seeds were stored for 120 days in winter, the seeds of the seeds could promote their ripeness and relieve dormancy effectively, Emergence neat. The result of germination test in spring showed that the seed germination rate of wild Sorborianus was lower, and the difference of germination rate was significant among different treatments. Among them, germination was the best when treated with warm water at 60 ℃ for 48h and then treated by outdoor diurnal temperature change for 10 days , Can reach 48%.
