Germination of Triticum aestivum L.: Effects of Soil–Seed Interaction on the Growth of Seedlings

Seed size, sowing depth, and seed disinfection can affect germination seedling establishment, which, in turn, directly crop growth yield. The current study was comprised of two experiments, the first which conducted laboratory, a second performed under glasshouse conditions. objective these experiments to investigate effects on initial selected wheat (Triticum aestivum L.) cultivars. treatments laboratory experiment were arranged completely randomized design, included: (Ι) four cultivars (Pishgam, Haydari, Soissons, Mihan), (ΙΙ) size classes (x < 2.25 mm, x > mm), (no-disinfection disinfection), (ΙΙΙ) with five replicates. In addition aforementioned treatments, effect planting depth (4, 6, 8 cm) also investigated subsequent experiment. best results obtained at 4 cm, non-disinfected treatment, using large seeds. contrast, lowest percentage speed vigor index observed seeds sown cm disinfected small Large contain larger nutrient stores may improve indices, would therefore result improved germination, followed by faster coleoptile growth, higher dry weight vigor. These data illustrated that Pishgam Haydari had inhibitory upon length, could be related fungicide’s chemical composition. Unlike other cultivars, did not show significant Soissons cultivar. Based our data, order both plant development; it is necessary select high-quality, seeds, planted specific have been treated an effective disinfectant; all will for cultivar question. Overall, has provided useful information seed, characteristics form basis future field scale trails.
