ABSTRACT

An experiment was carried out to evaluate the residual effect of partial girdling on fruit quality and bark recovery of Satsuma mandarin three years after the date of girdling operation. In 2003, fruit trees located in the University Farm of Ehime University received the girdling treatment of 10 cm and 20 cm width to compare the effect with ungirdled (control) branch. After three years, the bark recovery was found to be significantly higher in the branches that received girdling of 10 cm width than 20 cm girdling treatment. The fruit size, total soluble solid content and the titratable acidity were not significantly different among the three treatments. However, the largest fruits (98.4±3.52 g) were obtained from the ungirdled branch while the highest brix (10.5 ± 0.25 %) was recorded in the fruits harvested from the 10 cm girdled branches.
