食用 纖維素 資源의 選拔에 關한 硏究 Ⅲ. 밀 品種에 있어서 pentosan 含量과 種實硬度의 關係

Studies on selection of dietary fiber resources Ⅲ. Relationship between endosperm pentosan content and grain hardness in different classes of wheat cultivars

In this study, the relationship between grain pentosan level and grain hardness was investgated using four Korean and seven American wheat cultivars. Water soluble pentosan content was ranged from 1.05 to 1.41% and total pentosan content was 4.63~6.33%, and hard and domestic wheat cultivars were higher in pentosan content than soft and club wheat. Environmental variation of pentosan and protein contents due to location differences was observed, and hot and dry environment at maturity produced high level of pentosan and protein in wheat grain. Water soluble pentosan, total pentosan and protein contents showed significant correlation coefficients, and wheat cultivars, Tapdongmil and Chokwang had content of grain pentosan. NIR spectra is considered to have a capability to differentiate between hard and soft wheat endosperm trait.
