Improvement of sugarbeet (Beta vulgaris) seed germination with water treatment

Germination of seed and establishment of seedling in sugarbeet could be influenced by chemical inhibitors of seed coat, seed hardness and impermeability to water and oxygen as well as seed reserves. Uniform seeds of cv 9597 were studied using a completely randomized design with 4 replications. Samples of 100 seeds were washed by distilled water, diluted hydrocholoric acid and diluted hydrochloric acid with was neutralized by sodium hydrobxide at the end of washing treatment. Each of the above treatments was applied at 2, 4 and 6 hours. Samples were sterilized by diluted sodium hypochlorite solution. Germination percent and the rate of germination in germinator and sand medium were claculatcd. Results showed that the type of treatment for washing couldnʹt influence the percent and the rate of sugarbeet germination seed in the germinator. But the rate of germination in sand medium increased significantly through water treatment. In addition, the time of applied treatments influenced the percent and the rate of germination in germinator and sand medium significantly. Interaction effects between the type of treatments and the time of washing also influenced the percent of germination in germintor and the rate of germination in sand medium significantly. Such that, the 6 hours washing with distilled water increased the percent of germination in germinator 1.87 times and the rate of germination in sand medium 43% in comparison with control, non-washed seed treatment.
