【摘要】 对金沙江干热河谷地区麻疯树(Jatropha curcas L.)种子中具有抗肿瘤活性的核糖体失活蛋白curcin含量及其生物学性状进行研究。结果表明,用酶联免疫吸附法测定麻疯树单颗种子的curcin含量为0.275～3.183 mg g-1,平均(1.369±0.055)mg g-1。Pearson相关性分析表明:单粒麻疯树种子的curcin含量与种子其他性状的相关性均未达显著水平,但与种子质量、种仁质量及含油量存在一定程度的负相关,而与出仁率和可溶性蛋白含量存在一定的正相关,且与可溶性蛋白含量的正相关系数(0.190)和与含油率的负相关系数(–0.177)较高。这表明可在金沙江干热河谷地区开展高curcin含量麻疯树种质资源收集和选育工作,以及培育高含油量、高curcin含量的双高品种,以提高麻疯树生物燃油产业的综合效益。更多还原

【Abstract】 Curcin content and some seed traits of Jatropha curcas seed collected from Dry-hot Valley of Jinsha River were determined.The results showed that curcin content by Enzyme-linked immunosorbent assay ranged from 0.275 to 3.183 mg g-1 with average of(1.369±0.055) mg g-1.Pearson correlation analysis indicated that curcin content had no significant correlations with some seed traits,such as seed weight,kernel weight,oil content,seed-kernel rate and soluble protein content.There were a certain negative correlation between curcin content and seed weight,kernel weight and oil content,on the contrary,curcin content had a certain positive correlation with seed-kernel rate and soluble protein content.It suggested that germplasm collection and breeding with high curcin content of?Jatropha curcas could perform in Dry-hot valley of Jinsha River,and breed new variety with high oil and curcin contents of Jatropha curcas,so as to improve comprehensive efficiency of Jatropha curcas bio-fuel?industry.更多还原
