This study was conducted to investigate the growth characteristics of four barley cultivars to NaCl stress of 100mM on 10 March (Tillering stage) and 10 April(Panicle formation stage). Plant grown in Wagner pot(1/5,000 a) with sand culture. Plant height, root length, leaf number and tillering number reduced by NaCl stress and tillering number was shorter than any other character. The reduction of those with NaCl treatment was more severe in 10 March treatment compared to in 10 April it. Leaf, root and straw weight were decreased with NaCl treatment and root weight was more sensitive than any others on 10 March and 10 April treatment. One hundred grain weight (g) in grain component was the most severe in 10 March treatment and panicle number per plant was the most severe in 10 April treatment. The result also varied depending on the cultivars and the time of NaCl stress. In terms of yield component, salt sensitivity was low in order of Bunong, Chalssalbori, Dongbori 1, and Neulssalbori in 10 March and Neulssalbori, Dongbori 1, Bunong and Chalssalbori in 10 April treatment by 100mM NaCl.
