Content Changes of Lignin,Cellulose and Soluble Sugar and Their Correlations with Hollowness during Storage in Radishes
In this experiment, changes of lignin, cellulose and soluble sugar content and hollowing index of radishes during storage were studied and their correlations were analyzed.The results showed that hollowing index increased significantly in 50 days after storage.Lignin and cellulose content increased markebly in 40 days after storage,and soluble sugar rose in 30 days and dropped after 30 days.Positive relations between hollowing index and lignin and cellulose were significant and negative relation between hollowing index and soluble sugar was not significant,indicating the increase of lignin and cellulose was the main reason causing hollowness.
