Effect of fruit load on yield and quality of pummelo
The effect of fruit loading on yield and quality of pummelo (Citrus grandis (L.) Osbeck 'Thong Dee') was studied using varied numbers of fruit on the tree. Twelve 13-year-old pummelo trees planted at the farmer's orchard in Chaiyaphum province, northeast of Thailand were selected. The experiment design was a randomized completely block design (RCBD) with 3 fruit thinning systems (4 replications), 0, 10 and 20% fruit thinning from whole fruit number in each tree. The results showed that 20% fruit thinning had the highest grade A fruit size (40.53%). In addition, the fruit drop had the lowest percentage in this treatment. However, fruit thinning had affected the fruit length/circumference and reduced the ascorbic acid content in the juice.
