摘要：

摘要：研究了6个甘薯品种在适温贮藏期间呼吸强度、干率、淀粉、可溶性糖、还原糖、蛋白质的变化及其相关性分析。结果表明，甘薯适温贮藏期间呼吸强度、可溶性糖含量变化呈高到低再到高的趋势曲线，且与其干率密切相关；淀粉含量在贮藏期呈现缓慢下降的趋势；甘薯块根干率与淀粉含量、呼吸强度呈极显著正相关，与蛋白质含量呈显著正相关；干率、淀粉含量和蛋白质含量都与还原糖含量呈极显著负相关；蛋白质与可溶性糖呈极显著负相关；可溶性糖与还原糖呈极显著正相关。

Abstract:

Abstract： This study evaluated the changes and their correlative analysis from 6 varieties sweet potato in proper temperature during storage of respiratory intensity ,dry matter rate, starch, soluble sugar, reducing sugar and protein . The results show that changes in respiratory intensity and soluble sugar content was high to low then to high, and is closely related to its dry matter rate in the storage period; starch content and respiratory intensity was highly significant positive correlation with dry matter rate; dry rate, starch content and protein content were significantly negatively correlated with reducing sugar content; protein and soluble sugar was significantly negatively correlated; soluble sugar and reducing sugar was very significant positive correlation. The results were as follow : starch content and respiratory intensity was significantly and positively correlated with dry matter content.
