Effects of Salt Stress in Germination Stage in Rice Genotypes (Oryza sativa L.)

Aim and Germination stage is an important growth plant stage that is often affected by environmental stress including water and salinity stress. The aim of this study was to investigate the effects of Sodium Chloride Salinity on Seed Germination of Rice and found to have more salt-tolerant cultivars. In order to study germination of three rice varieties named Gharib, Musa tarom and Abji buji at different levels of salinity. The experiment was carried out based on completely randomized design with four replications. Salt treatments were controlled in 0, 4, 8 and 12 ds/m-1. The results of data analysis showed that salt effect on studied varieties and interaction of varieties × salt on the studied characters were significant in %1 level. In this research some characters including rate and percentage of germination, gemule length, and radical length were studied. With increasing salt all evaluated characters decreased. Statistical analysis of data showed significant difference in rice genotypes. With increasing salt all evaluated characters significantly decreased.
