Abstract : |
Different genotypes of Jute (Corchorus capsularis UPC 94, UPC 7716 and IRC 212) and (Corchorus olitorius S1 and S25) seeds were selected to study the effects of salinity stress on germination and subsequent seedling growth and concomitant changes of protein banding pattern. Different concentrations, of NaCl (1000, 3000 and 5000 ppm) were used. Generally, seed germination and growth parameters of seedlings dropped below the control levels at high concentration of NaCl (5000 ppm). However the different genotypes of Jute show higher growth at (1000) ppm as compared with the control. Protein banding patterns of Jute genotypes which previously treated with the different concentrations (1000, 3000 and 5000 ppm) of NaCl were studied. It has been found that the contents of proteins in the seedling of some different Jute genotypes were considerably increased with increasing salt stress compared with the control. Qualitative and quantitative changes of protein pattern suggested a modulation of gene expression. The results were interpreted in the light of recent arguments on salinity stress and proteins., Different genotypes of Jute (Corchorus capsularis UPC 94, UPC 7716 and IRC 212) and (Corchorus olitorius S1 and S25) seeds were selected to study the effects of salinity stress on germination and subsequent seedling growth and concomitant changes of protein banding pattern.
