| Abstract | ||
| In this study grains of rice varieties (Sakha 104 and Giza 178) were tested for the response to different concentrations of cobalt sulphate. There was a significant increase in percentage of germination at the low levels of the treatment solution. High cobalt levels caused a reduction in length of radicle and plumule in case of Sakha 104 (above 44.5 µm) and (above 10 µm) in case of Giza 178. The low levels of cobalt were also associated with an increase in vigor index, dry matter of root and shoot of seedlings. The results indicate that high levels of cobalt might be poisonous and have harmful effect on the germination and seedling growth in rice plants. | ||
