초록

이 연구는 기능성 사료용 보리의 생산 기술을 개발하기 위한 기초자료를 얻고자 식물체 전체에 안토시아닌이 함유된 겉보리인 보안찰보리 품종을 이용하여 추비 및 수확시기별 생육과 사료가치 및 안토시아닌 함량의 변화를 검토한바 그 결과는 다음과 같다. 1. 초장은 추비가 빠를수록 유의하게 컸고, 수확시기에 따른 유의성이 없었으며, 건물률은 추비시기가 빠를수록, 수확시기가 늦을수록 높았다. 2. 단백질 함량은 추비와 수확시기가 늦을수록 높았으나, NDF, ADF 및 TDN 함량은 추비시기와 수확시기에 따른 유의성이 없었다. 3. 총 안토시아닌 함량은 추비시기가 빠를수록 증가하였으며, 조성별로는 cyanidin-3-g1ucoside(C3G)와 delphinidin 에서 유의성이 있었다. 4. C3G와 delphinidin은 출수 후 25일, pelargonidin-3-glucoside (P3G), cyanidin 및 pelargonidin은 출수 후 30 일부터 검출되었으며, 수확시기에 늦어짐에 따라 유의하게 증가하였다.

This experiment was carried out to evaluate the effects of top dressing of nitrogen and harvest time on the growth, feed value and anthocyanin content for developing functional feed of colored barley. A colored barley cultivar, Boanchalbori, was tested in this experiment. Top dressing was applied at seven separate growth stages, regeneration time (RT), and intervals of 20, 30, 40, 50, 60, and 70 days after RT, and harvested at different time from 20 days after heading (DAH) to 40 DAH with 10 days interval in split plot design with three replications. Plant height was increasing with earlier top dressing, but not affected by harvest time. Percent dry matter was increasing with earlier top dressing and later harvests. Protein content was increased with later top dressing and harvests, but percent NDF, ADF and TDN was not significant. Total anthocyanin content was increased with earlier top dressing, included increasing C3G (cyanidin-3-glucoside) and delphinidin. The C3G and delphinidin were detected from 25 DAH and P3G (pelargonidin-3-g1ucoside), cyanidin and perlagonidin from 30 DAH. Their contents were increased significantly as harvest was delayed. This experiment provides some interesting results with respects to optimum top dressing and harvest time for the functional feed production of the colored barley.
