Abstract: The experiment aims to determine characteristics related to germination under salinity stress in two Thai rice varieties [Chai Nat 1 (CNT1) and Pathum Thani 1 (PTT1)] from both non-soaked and soaked seed before sowing. The rice seeds were sowed using the germination paper method and treated with different water salinity levels, including 0 mM as control (0 dS/m), 50 mM (5 dS/m), 100 mM (10 dS/m), and 150 mM (15 dS/m) of sodium chloride (NaCl) solution. The germination characteristics were measured and analyzed separately for each rice variety in soaked and non-soaked seed at one week after sowing. The experiments were arranged in a completely randomized design (CRD) for four treatments of salinity level. The results showed most characteristics, excluding germination percentage (GP), were significantly affected by salinity. Each characteristic also showed different responses between CNT1 and PTT1. The soaked seeds had higher values on all characteristics than non-soaked seeds in both varieties. Shoot length (SL) reduction was started to be observed at 100 mM NaCl in PTT1 while the salinity at 150 mM showed the same results in CNT1. In addition, soaking had a greater role in shoot lengthening in PTT1 than CNT1, compared between soaked and non-soaked seeds in each salinity levels. Hence, seed-soaking might be an alternative method to provide certain degree of salinity tolerance for germinating rice seedling in environmentally freintly fashion.
