| This study was conducted to establish the minimum harvesting time of 'Campbell Early' grape with girdling of 8 years old vines by the investigation of fruit quality. Girdling was performed as 5~7mm width at 1.0m height with a Y-trellis system on July 5th at Gimcheon, Gyeongbuk province. Skin color, soluble solids contents, sugar content, organic acid, and titratable acidity were analyzed every seven days period after the girdling. From 14 days after the girdling, pericarp color changed quickly as compared to the control, and also decreased b value and increased a value of Hunter L were observed. The content of organic acids decreased quickly as 0.85% as compared to the control's one, 1.10%. Sugar-acid ratio increased rapidly from the 21days as 15.1 against 10.8 of the control at harvesting time. After 14days, sugar content was abruptly increased such as fructose and glucose, that is 7days faster than the control. In harvesting time, their contents were high as $64.5mg{cdot}g^{-1}FW$ and $61.0mg{cdot}g^{-1}FW$ as compared to $56.1mg{cdot}g^{-1}FW$ and $53.7mg{cdot}g^{-1}FW$ of the control respectively. Among the content of organic acids, malic acid decreased quickly than the control's one in coloring time. The content of tartaric acid was obviously lower as $4.13mg{cdot}g^{-1}FW$ than the control's one, $5.96mg{cdot}g^{-1}FW$ in harvesting time. From these results, we assume that the harvesting of girdled 'Campbell Early' grape should be started in 42days after the girdling, when sugar-acid ratio is above 15. |
