تأثیر سیلیکون بر پارامترهای جوانه‌زنی بذر ارقام مختلف گندم

In order to investigate the effects of silicon on germination in four wheat cultivars, an experiment was conducted as factorial based on completely randomized design with three replications. In this research, two factors were evaluated: first, four cultivars (Parsi, Chamran, Sivand, Pishtaz) and second, four levels of silicon (0, 20, 40, 60 mM). Investigated characteristics consisted of shoot and root dry and fresh weight, shoot and root length, mean germination time, germination percentage, vigor index and seedling water content. Results showed that silicon effect on mean germination time, germination percentage, shoot and root fresh and dry weight and shoot and root length was significant, and concentrations of 40 mM of silicon had the greatest effect compared with other treatment. Intraction of silicon and cultivar on root and shoot dry weight, germination percentage and seedling water content was significant. Among studied cultivars, the greatest vigor index, germination percentage and root and shoot fresh weight was observed in Parsi.
