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.
