| dc.description.abstract | Salt tolerance of rice plant (Oryza sativa L.) varies among varieties as well as among growth stages. Laboratory and greenhouse experiments were conducted to study the varietal tolerance during the germination and the seedling stages. The seeds of PB 28 and PB 32, susceptible and tolerant varieties, respectively, were germinated in petridishes with filter paper saturated with 0, 0.25, 0.50, 1.00, 2.00, and 4.00 % (W/V) NaCl. The germinating seeds were transplanted to soil culture salinized with 0.30 % NaCI. The seeds unable to germinate in 10 days were throughly washed to remove the NaCI and then were germinated in petridishes with filter paper saturated with water. | id |
