Abstract▼
To evaluate the possibility of all year-round production of citrus tangor Shiranuhi[(Citrus. unshiu × C. sinensis) × C. reticulata], this study was investigated the characteristics of tree and fruits with heating times from 2003 to 2005. 1. To examine the effect of heat-beginning time on fruits.
To evaluate the possibility of all year-round production of citrus tangor Shiranuhi[(Citrus. unshiu × C. sinensis) × C. reticulata], this study was investigated the characteristics of tree and fruits with heating times from 2003 to 2005. 1. To examine the effect of heat-beginning time on fruits. commodity, total 4 heat-beginning times were treated such as heating from January, from February, from March, and non-heating in plastic film house. 2. The harvesting time took from 274 days to 318 days and was longer against heat-beginning times in plastic film house. The characteristic of shoot development, soluble solid and acidity of fruits were influenced more by temperature and water management in growing season than heating time. The peel color(a*) was lowered in early heating time but it was not effected on the fruit quality. So the 4 types could be use in 'Shiranuhi' culture in Jeju. 3. As for the fruit quality with setting location on the tree, the fruits set on the upper part of the tree had larger fruit size, longer neck on the stem (penducl) end, and was high soluble solid content and acidity. 4. Secondary, we also examined to grow under early heating condition from November to December for early fruit sale. It was possible to harvest in October but their fruits quality was very row such as greenish peel color, low soluble solid content, and separated peel from its pulp. 5. As the result of sensory evaluation of the fruits growed under early heating conditionCheated from December), the rate of good, normal and bad grade were 24.6%, 47.9 and 27.5% respectively. It meaned, concerning 'Shiranuhi' as high quality fruits, that the results were not good. 6. To improvement the fruit quality under early heating condition Cheated from December), the fruits covered several paper bags on September. Peel color was most improvement in covering with yellow paper bag, but it was no effect on fruit quality.
