초록

When three cultivars, “Shinsunchalbyeo”, “Nokmi” and “GW-05-01”, which was collected from native glutinous rice, were exposed to increased salinity stress in exogenous solution and duration of salt stress, leaf relative water content (RWC), root water uptake and chlorophyll fluorescence were observed the significant decrease at ≥500mM NaCl concentration for 4 day stress. These decrease in leaf RWC showed 69%, 77% and 67% for Shinsunchalbeyo, Nokmi and GW-05-01, respectively, in water uptake these effects showed 84%, 85% and 91%. The difference in Fv/Fm of plants treated with 500mM NaCl showed 0.62, 0.68 and 0.78 compared with 0.78, 0.81 and 0.75 in control treatment. The effects of NaCl stress in rice seedlings indicate that the leaf RWC and photosynthetic capacity is more sensitive GW-05-01 in comparison with Shinsunchalbyeo and Nokmi, and water uptake in root is more resistant. Average plant height in Shisunchalbyeo, Nokmi and GW-05-01 showed 107, 102 and 111cm, and the 1000 grains weight were 25.5, 20.3 and 21.8, respectively.
