피맥5품종, 과맥5품종 및 맥주맥5품종 등 15품종을 공시하여 대맥절간의 조직형태와 외부형태의 품종간 차리 및 형질들간의 상호관연성을 구명하기 위하여 실시한 시험으로 그 결과를 요약하면 아래와 같다. 1. 상위절간장(상위로부터 1∼3절간)은 맥주맥>피맥>과맥의 순으로 길었으며, 하위절간장 (상위로부터 4∼5절간)은 과맥>피맥>맥주맥의 순으로 길었다. 2. 절간의 굵기는 과맥>피맥>맥주맥의 순으로 굵었고, 올보리, 세도하다가, 무안보리 및 광성이 굵은 경향이었다. 3. 간벽 두께는 상위절간(과맥>피맥>맥주맥), 하위절간(피맥>맥주맥>과맥)의 순으로 두꺼웠다. 4. 상위 제 1절간의 대유관속수는 피맥품종들이 과맥과 맥주맥품종들 보다 많았다. 5. 대유관동 크기는 피맥과 과맥품종들이 맥주맥품종들 보다 큰 경향 이었다. 6. 대유관동 크기와 간벽 두께 및 절간의 굵기와는 유의한 정상관을 나타냈고, 간벽 두께와 절간장 및 간장과는 부의 상관관계를 나타냈으며, 간벽 두께와 절간 굵기와는 유의한 정의 산관을 보였다.
Experiments were carried out to find the varietal differences in histological structure and outer characteristics, and its relationships between each characters in the internodes of 15 barley varieties (5 covered barley, 5 naked barley and 5 malting barley). The length of 1st-3th internodes from the top was longer in malting barley varieties, covered barley varieties and naked barley varieties in the order, but of 4th-5th internodes was longer in naked barley varieties, covered barley varieties, and malting barley varieties in the order. The diameter of naked barley varieties internodes was much thicker that of malting barley varieties. The thickness of culm wall in 1st-3rd internodes was thicker naked barley varieties, covered barley varieties, and malting barley varieties in sequence and in 4th-5th inter-nodes was covered barley varieties, malting barley varieties, and naked barley varieties in the order. The number of large vascular bundles in covered barley varieties had more than that of naked barley varieties and malting barley varieties in 1st internodes. The size of large vascular bundles in covered barley varieties and naked barley varieties was larger than that of malting barley varieties. The size of large vascular bundles had significant positive correlation with thickness of culm wall and the diameter of internodes. The thickness of culm wall was negatively correlated with the length of internodes and culm, but positively correlated with the diameter of internodes.
