영문 초록

The study was made to establish the beneficial practical cultivations considering the processes of spike differentiation with the nine varieties of barley and wheat. The four varieties; Suwon No. 18, Buheung, Yuksung No. 3 and Yungkwang, were cultivated in the central region of Korea and examined at Suwon. Five other varieties; Kyungnam No. 89, Sekidorisaki No. 1, Suwon No. 18, Norin No. 4 and Norin No. 12, were cultivated at Chinju in the southern region. In both barley and wheat, the differentiation was started early to increase plant height. The year variation in spike differentiation was larger at Chinju compared with Suwon and considerable variation in spike differentiation was also found in different varieties. Only one of the material varieties, Yungkwang, shown slightly the year variation. The elongation of internode was late in barley compared with wheat and in Chinju compared with Suwon. The results demonstrated that practical cultivations coincide to the differentiation and development of spikes should be done earlier by approximately 10 days compared to the time of conventional cultivations already recommended by agronomists.
