Abstract
To investigate the effect of leaf removal on enlargement and coloring of persimmon fruits (Diospyros kaki L. cv. 'Fuyu'), four treatments control (0%), 20%, 50%, and 100% depend on leaf removal of fruit bearing branch were applied to persimmon trees. Sunlight intensities around fruits with treatments depend on removal level, compared with natural sunlight intensity (100 percentage level), was 7.9%, 13.6%, 16.4%, and 30%, respectively. Hunter $a^*$ of the fruit with control and 20% removal treatments to harvest season increased continuously. $Chroma^*$ of the fruit since the removal treatments of leaves increased continuously in all treatments, but from seventh week that had a decreasing tendency. The fruit weight and diameter were significantly heavy and short in treatments with 100% removal level. L/D ratio of the fruits had a significant difference between control and the other treatments. Soluble solids of the fruits lowed significantly in treatment with 50% removal level. Hunter $a^*$ of the fruits was better in treatments with control and 20% removal levels, Hunter $b^*$ and $Chroma^*$ lowed significantly in treatment with 20% removal level. $\beta$-Carotene and lycopene concentration of the fruits lowed in treatment with the higher of removal level, total chlorophyll contents had the opposite tendency to the pigments. All results considered, removal level of leaves around fruit on bearing branch in fruit maturation stage had effect on fruit coloring improvement.
