【目的】探明不同采收期山桐子果实质量及差异,为山桐子的质量评价、采摘、加工利用、苗木繁育及推广栽植提供参考。【方法】以21 a生山桐子人工林果实为研究对象,对不同成熟度果实的表型性状、含油率、油脂成分和种子萌发情况等进行测定分析。【结果】随果实成熟度的增加,果皮颜色由青绿色变为深红色,果实大小、果形指数、单果鲜质量、含水率、含油率、种子千粒质量、种子发芽率、饱和脂肪酸含量均呈先上升后下降趋势;不饱和脂肪酸表现为先下降后上升的趋势。相关性分析结果显示,果实含油率与果穗宽、单串果穗鲜质量、单穗果实鲜质量、单果鲜质量、果实横径均呈极显著正相关关系(p<0.01)。10月左右山桐子果实成熟度高、单穗果实个数最多,单穗果实鲜质量、单果鲜质量及果实横径均达到最大,含油率较高,为21.87%,不饱和脂肪酸达85.61%,亚油酸含量72.67%,发芽率最高,可达93.33%。【结论】不同采收期山桐子果实品质存在差异。果实用作油脂原料和实生苗繁育材料时,最佳采收期为10月。
