摘要
分别选用11个品种鲜甘薯和14个品种甘薯粉,对甘薯干率、淀粉、蛋白质、可溶性糖和还原糖含量等品质特性与乙醇产量进行相关性研究。结果表明,不同品种甘薯乙醇产量差异极显著(P<0.01);乙醇产量与鲜甘薯的干率呈极显著正相关,与淀粉和蛋白质含量呈显著正相关;乙醇产量与甘薯粉各品质性状之间相关性未达到显著水平;乙醇产量与鲜甘薯品质性状之间线性回归分析呈显著水平,建立的回归方程为:Y=2.086+0.162X1+1.064X2+0.248X3(P<0.05)(Y为乙醇产量,X1为淀粉、X2为蛋白质、X3为还原糖);乙醇产量与甘薯粉品质性状之间线性回归分析未达到显著水平。
Eleven fresh sweetpotato varieties and fourteen sweetpotato powder varieties were selected to study the relationship between the quality traits like dry matter,starch,protein,soluble sugar,reduced sugar content and ethanol yield with correlation analysis methods.The results showed that difference of ethanol yield was significant among sweetpotato varieties,ethanol yield showed significantly positive correlation with dry matter content（P0.01）,starch content（P0.05） and protein content（P0.05） of fresh sweetpotato,and the correlation between ethanol yield and quality traits of sweetpotato powder was not significant.The regression equation between ethanol yield and fresh sweetpotato quality traits was established as follows： Y=2.086＋0.162X1＋1.064X2＋0.248X3（P0.05）（Y-ethanol yield,X1-starch,X2-protein,X3-reduced sugar）.The regression equation between ethanol yield and quality traits of sweetpotato powder was not significant.
