영문 초록

This study was conducted to find out the suitable NaCl concentration and time for investigating the varietal differences for salinity tolerance in barley. Seeds of 17 varieties were exposed to eight levels of NaCl concentration ranging from 0 to 350mM at 20℃. The average NaCl concentration that inhibited 50% germination of the viable seeds was 306mM and standard deviation was highest in 300mM NaCl. The relationship between the NaCl concentration that inhibited 50% germination of the viable seeds and the germination percentage in 300mM NaCl was correlated with high correlation coefficient, below 1% level of probability, and the germination percentage was correlated with the germination speed at 4th day after sowing in 300mM NaCl. The varieties used could be classified into three groups by the germination speed at 4th day after sowing in the 300mM NaCl. Nulssalbori, Hinssalbori and Olbori were classified into the tolerant group, Mudeungssalbori, Duwonchapssalbori and Youngsanbori, Saessalbori, Kinssalbori, Hinchalssalbori, Sacheon 6 bori and Tapgolbori, Saechalssalbori, Naehanssalbori were classified as the semi-susceptible group, and Songhakbori, Chalbori, Chunchubori and Kwanghwalssalbori were classified as the susceptible group.
