Influence of Fungicides Application and Seed Processing on Sunflower Seed Quality

摘要

The aim of the research was to determine influence of methods of seed processing and application of fungicides on mass of 1000 seeds, intergrowth energy and seed germination of sunflower hybrids ‘Favorit’ and ‘Apolon’ in 2005 and 2006. Selected untreated seeds of both sunflower hybrids (control) had a minimal mass of 1000 seeds (55-59 g), intergrowth energy (18-37 %) and seed germination (39-52 %). In both years of research maximal seed quality, mass of 1000 seeds (67-69 g), intergrowth energy (84-85 %) and seed germination (87-89 %) were after application of the method of seed processing T-4 and aft er the fungicides application TF-4. The results showed that unfavorable weather conditions over the production year result with low quality seeds. However, by applying the target methods of seed processing and optimal combination of fungicide doses we can produce the sunflower seeds with regular legislation quality for the market.
