收穫期와 貯藏條件에 따른 단옥수수의 品質變化에 關한 硏究 = Effects of Harvesting Time and Storage Conditions on Quality of Sweet Corn(Zea may. L.)

다국어 초록 (Multilingual Abstract)

Experiments were carried out to determine the optimum harvesting time and the optimum storage temperature and duration of sweet and super sweet corns. Days to silking could be enchanced by vinyl house, vinyl tunnel, or vinyl mulching compared to the conventional bare soil cultivation. Grain development in dry weight was delayed in the case of super sweet corn (NES) and vinyl house or tunnel, compared to sweet corn (CBS70) and vinyl mulching or bare soil cultivation. Soluble solids in the grains were higher and the accumulation was faster in the case of sweet corn compared to the super sweet corn. The optimum harvesting time for sweet corn (GCB70) and super sweet corn appeared to be 24 and 27 days after silking respectively. Though, the harvesting time was delayed by 1 to 3 days by vinyl house or tunnel cultivation. The dominant sugar in the grains at harvest was sucrose for the two sweet corns. But the sucrose contents were much higher in the case of super sweet corn. The decrease of suger during storage could be reduced by cool or freeze storage. Also the decrease rate was much slower for the super sweet than sweet corn.
