Whereas, the trees under SRDI-1 and MRDI-2 showed a higher growth rate than the other two treatments during late July and early August, and from early July to fruit harvest, the average growth rate under SRDI-1 was 8.2% higher than that of
control (p < 0.05), which resulted in the largest final fruit size in the SRDI-1 and MRDI-2 treatment, measuring 100 cm3 (in 2010).
