摘　　要：本研究对西昌、攀枝花、仁里、海口、三亚、东方六地的麻疯树种子进行资源调查研究,结果显示六个地区麻疯树种子胚乳核糖体失活蛋白含量均值为1.8770~2.5602mg/g,由高到低依次为西昌、三亚、海口、仁里、攀枝花、东方,且地区间差异较大.各地区内部种子胚乳核糖体失活蛋白含量数据分析显示,仁里地区种子胚乳核糖体失活蛋白含量变异系数最大,为14.6189;海口地区的变异系数最小,为7.1876.麻疯树种子性状相关性分析结果显示胚乳核糖体失活蛋白含量与百粒重、出仁率值在0.01水平上没有相关性,与含油率相关性不显著,与可溶性蛋白含量在0.01水平上低度负相关.综合各项指标认为西昌地区的麻疯树种子核糖体失活蛋白含量较高,可作为现阶段核糖体失活蛋白应用的材料来源之一.The Jatropha curcas L. seeds collected from 6 individual locations （Xichang, Panzhihua, Haikou, Sanya and Dongfang） were analyzed in this study. The results showed that the average curein contents in the endosperms were among 1. 8770-2. 5602 mg/g following the order from high to low.. Xichang, Panzhihua, Haikou, Sanya and Dongfang, showing large content variation among them. The analysis on the coefficient of variation （CV） of curcin contents within a population found that the highest CV （14. 6189） is from Renli while the lowest one （7. 1876） from Haikou. The correlation analysis sug- gests non-relationship between curcin content with 100-seed weight and kernel yield, non-obvious rela- tionship with oil content and low negativle relationship with soluble protein contents at the level of 0. 01. Based on these data, the seeds from Xichang with relative higher curcin content could be used as one of resources for the further application at present.
