| Abstract | ||
| Seed enhancement methods are applied to eliminate or decrease adverse environmental stress effects and increase seed germination rate and vigor of rangeland plants. The coated seed process is from amplifier ways that stick various materials on the outer surface of the seeds that minimize the negative environmental effects and increase the ability of plant establishment. The aim of this study was to assess the effects of seed coating methods on germination of Triticum aesativum, cultivar Sardariin different moisture stress levels and sowing depths. This experiment was conducted with a completely randomized design with four replications. Treatments of covering material was used in four levels including, non coating levels (NC), mineral-based coating (CC), organic- based coating (OC), and hydro gel-based coating (HC). Moisture treatments were used in three levels of moisture soil content. Two planting depth and three seed diameter including M9%, M14% and M21% were used. During the test, speed of germination was evaluated. The results showed that moisture treatments and planting depth at had highly significant effect and there was no significant effect of coating treatments. Also the interaction between type of covering material and soil moisture was not significant for germination speed, but there was significant difference between treatments of seed size in M9% and M21%. Although in the triple interaction, increasing moisture and planting depth enhanced the speed of germination process, but it was not significant statistically. The seedling growth of covered seed developed significantly, so it can be useful in enhancing plant performance. | ||
