| This experiment was conducted to utilize the basic information for salinity tolerance using Dongjinbyeo, Mangeumbyeo, Hwangkeumcheong, Nihonbare and Norin 29 as Japonica rices. Salinity level, 0.3, 0.6, 0.9, 1.2 and 1.5%, were treated and germination rate, recovering rate and radicle length of seeds were measured. The germination rate showed the range from 92 to 100% at the concentration of 0.6% of NaCl. However, it decreased at 0.9% and rapidly reduced at 1.2% above for all varieties. Recovering rate for salt damage of seeds was favored in Dongjinbyeo, Mangeumtyeo, Hwangkeumcheong about 92 to 98% after two days of transfering, but 73 to 76% in Nihonbare and Norin 29 were represented. The radicle length revealed shorter with decreased salinity level, particularly all varieties showed one centimeter less at the concentration of 1.2% above. |
