Twenty days before the citrus fruit was picked, the solutions of various concentrations of MAR and MA—3 were sprayed on the branches, leaves and fruit of citrus three times at the intervals of 5 to 7 days. After the fruit was picked, the contents of acid, single sugar, cane sugar and total sugar of the fruit were determined. The results of analysis of variance showed that the effects of the treatments on sugar increase were not significant (α=0.05). The effect of the content of the cane sugar on the total suger was the greatest of the three elements. The content of the acid seemed to have no relation with the content of total sugar.
