영문 초록

A study was carried out to find the relationship between internode characters and lodging resistance in barley varieties. Regardless of 8 varieties or 3 lodging resistance groups, the first internode length from the top was the longest, and that shorter and shorter go to lower internode. Among the internodes, positive correlationship between the one and the next were highly recognized except between the second and the thrid. The percentage ratios of each internode length to the culm length were in diversity according to varieties. But this phenomina were little different among the groups, especially between strong and weak ones. The third internode diameter in all varieties was the thickest. Mean internode diameter of strong lodging resistance group was thicker than that of the other groups. In the relationship of each internode diameter, most of them were highly positive correlationship except between the first and the forth and fifth, the second and the fifth internode. Of the mineral content in culm, phosphoric acid and kalium content were lower, but calcium content was higher of strong lodging reistance varietal group than those of the other groups. On the while, magnesium content was almost the same among groups, but silicic acid content of strong lodging resistance group(4.30%) was higher than that of the weak group(2.38%) and medium group(2.76%).
