- 摘要:
- 以采自浙江海盐、云南师宗、江苏镇江、湖北大别山、湖南古丈、湖南长沙等6个种源地的榉树种子为试材，采用称重、测量、TTC法及内含物测定等方法，研究了不同种源地种子形态结构、生活力、内含物含量及贮藏方式对种子萌发的影响。结果表明：6个种源地间以湖南古丈种源为最优种源，湖南长沙种质资源最差；湖南古丈种源种子最大，质量最好，饱满度最高，有生活力最高，为34%；采用湿沙贮藏效果最好，湖南古丈种源种子发芽率达24.15%，而湖南长沙种源种子室温贮藏效果最差，发芽率为0%。
- Abstract:
- Taking Z.schneideriana seeds from 6 provenance of Zhejiang Haiyan,Yunnan Shizong,Jiangsu Zhenjiang,Hubei Dabieshan,Hunan Guzhang,Hunan Changsha as materials,the methods of weighing,seed diameter measurement,TTC and seed inclusion determination were applied,the effect of the seeds morphology structures,seeds vigor,nutrient contents and storage method on the seed germination among different provenances were studied.The results indicated that the seeds from Guzhang of Hunan was the best among 6 provenances,the seeds of Changsha was the worst one.The seeds from Guzhang were the largest,best quality,plumpness,and the highest proportion was 34%.The wet sand storage effect was the best,Hunan Guzhang seed germination rate was 24.15%,while the Hunan Changsha seeds stored at room temperature effect was the worst,the germination rate was 0%.
