Physiological and Growth Responses of Thai Rice Genotypes to High Salinity Stress at the Seedling and Reproductive Stages.

ABSTRACT: The objectives of this study were to select Thai rice that are tolerant at the seedling stage and investigate their growth, physiological and yield responses at the reproductive stage in comparison with the standard salt-tolerant Pokkali (PK). Twenty-two local, commercial and improved Thai rice genotypes along with PK and salt-susceptible IR29 were evaluated at the seedling stage for salt tolerance using a 15 dS m^-1 saline solution with five replications. Ten selected genotypes were grown in pots with four replications and exposed to a 15 dS m^-1 saline level from early booting to the flowering stage. During the grain-filling stage, salt treatments decreased from 15 to 12 dS m^-1 and were sustained at this level until harvest. The experimental design for both
