摘要 以福建清流、南平、尤溪及江西九江无患子种子为供试材料,分析其种子形态及质量特征、种仁含油率和苗木生长状况.结果表明,福建清流无患子种子的长度、百粒重、发芽率均显著大于其他3个种源;无水乙醇对无患子种仁提取油脂效果最好,福建清流无患子种子的油脂提取率最高,为44.85%,显著大于其他3个种源;江西九江无患子1年生幼苗长势较差,其他3个种源长势相近.综合来看,福建清流无患子可作为南方无患子的备选优良种源. Four provenances of Sapindus mukorossi seeds from Qingliu, Nanping, and Youxi Counties of Fujian Province and Jiu- jiang County of Jiangxi Province were used as the experimental materials in this study. Data on seed morphology, seed quality, and seed oil content were collected and seedlings growth were compared. The results showed that the seed length, 100 grain weight, and germination rate of S.mukorossi seeds from Qingliu provenance were significantly higher than those from the other three provenances. The best extraction solvent of S. mukorossi seed oil was anhydrous ethanol; the highest oil extraction rate of 44.85% was obtained from the S. mukorossi seeds of Qingliu provenance, which was also significantly higher than the oil extraction rates from the other three provenances. Relatively slower growth was observed on one-year old seedlings of Jiujiang provenance in comparison to the seed- lings of the other three provenances. Therefore, the S. mukorossi seeds of Qingliu provenance was recommended as the elite prove- nance in Southern China.
