The fruit quality in terms of total soluble solid, soluble sugar and titratable acid was impacted remarkably by the water deficit
(Table 3). In 2009, the total soluble solid, soluble sugar and titratable acid all increased significantly in the RDI treatments, with the exception of titratable acid in MRDI-1 treatment. However, in 2010 there were no remarkable difference ofthe total soluble solid among SRDI-1, MRDI-2 and the control treatments.
