1)Data at 0 day represent the initial value of green peppers before storage at first day after harvest.
2)Means with the same lowercase letter within the column were not significantly different at p<0.05 with Duncan’s multiple range test.
3)NS, *, **, and *** nonsignificant or significant at p<0.05, 0.01 and 0.001, respectively.
