Abstract

The seeds of 20 barley cultivars were tested for aflatoxin contamination and susceptibility to infection by an aflatoxin-producing mold. When the samples were tested as they arrived, no aflatoxin was detected on any of them. When their moisture was raised to 25% and they were kept as $25^{\circ}C$ for 2 weeks, all expect 2 cultivars showed aflatoxin contamination. Aflatoxins $B_2$ and $G_2$ were not detected in this incubation period. After wetting (25% moisture) the samples, inoculating them with Aspergillus parasiticus conidia and storing them at $25^{\circ}C$ for 2 weeks, all cultivars were found heavily contaminated with aflatoxin, those with seedcoats more so than those without seedcoats.

보리품종별(品種別) aflatoxin오염(汚染)과 aflatoxin생성균(生成菌)의 감수성(感受性)을 조사(調査)하였다. 공시(供試)된 모든 시료(試料)에시는 aflatoxin이 검출(檢出)되지 않았으나 25%로 가수처리(加水處理)된 보리를 2주간(週間) $25^{\circ}C$에서 100% RH 상태하(狀態下)에서 저장(貯藏)하였을때 2개품종(個品種)을 제외(除外)하고는 aflatoxin $B_1$과 $G_1$이 미량검출(微量檢出)되었으며$B_2$와 $G_2$는 검출(檢出)되지 않았다. Aspergillus parasiticus에 의(依)한 aflatoxin 생성(生成)에 대(對)한 보리의 감염(感染) 감수성(感受性)은 대단히 컸으며, 겉보리가 쌀보리보다 aflatoxin의 생성(生成) 및 축적(蓄積)이 더욱 높았다.
