| This study was conducted to compare the storability of 6 chicory cultivars for producing chicon; 'Vintor', 'Focus', 'Metafora', 'Kibora', 'Nobus', and 'Redoria Red' grown in 2 regions: Chuncheon (plain region) and Pyeongchang (high land region). Chicons were produced from chicory roots that grown for 120days and then stored for over 120days at $2^{circ}C$ and 90% of RH conditions. To produce chicon, chicory root was forced at $18^{circ}C$ for 22days with suppling the nutrient solution ($KNO_30.54g{cdot}L^{-1}$, $Ca(NO_3)_2;1.02g{cdot}L^{-1}$, $MgSO_4;0.36g{cdot}L^{-1}$, $KH_2PO_4;0.21g{cdot}L^{-1}$, $K_2SO_4;0.10g{cdot}L^{-1}$, pH 7.0). Chicons produced from 6 different chicory cultivars packed with $25{mu}m$ ceramic film and stored for 25days at $8^{circ}C$. The fresh weight of chicon in MAP was maintained to 99.5% of pre-storage weight. The fresh weight of 'Redoria Red' was lowest in all cultivars, and that of Chuncheon region cultivated treatment was lower than Pyeongchang treatment. The $CO_2$ and $O_2$ concentration in chicon MAP were 2% and $10{sim}17%$. There were not significantly different among cultivars and between regions, although 'Redoria Red' cultivar showed highest $CO_2$ and lowest $O_2$ concentrations. The ethylene concentration in chicon MAP was $1.0{mu}{iota}{cdot}{iota}^{-1}$ and also didn't show any significant difference among all treatments. Chicon detoriorated visual quality with appearing russet spotting that result from ethylene gas. The visual quality of 'Redoria Red' cultivar decreased faster than the other cultivars. 'Metafora', 'Focus', and 'Kibora' maintained higher firmness of their leaf than the others, and the firmness was higher grown in Pyeongchang region cultivated treatments than in Chuncheon region. |
