영문 초록

This study was carried out to examine theeffects of storage duration on physico-chemical propertiesof milled rice. Rough rice of three rice ecotypes (Japonica,Tongil and F1 hybrids with Tongil back-ground) was storedfor 4, 16, 28 and 40 months without artificial environ-mental control in seed warehouse. And this materials wereinvestigated for seed germination rate, brown rice hardness,alkali digestion value (ADV), contents of protein, amylose,total sugar, and reducing sugar. Seed germination rate wassignificantly reduced with storage duration increased regard-from 28, and nil from 40 months storage in Japonica rices.And 54.0%, 67.9% in Tongil, and F1 hybrid after 40 monthsstorage, respectively. Brown rice hardness was not signifi-cantly affected by storage duration but showed significantgenotypic diferences. As the storage duration prolonged,sugar content and alkali digestion value increased, proteincontent declined while amylose content did not show cleartendency. Total and reducing sugar contents showed sharpincrease upto 16 months storage and thereafter steady in-crease, and the percentage of reducing sugar content out oftotal sugar content increased with extended storage duration.
