EFFECT OF DIFFERENT SUBSTRATUM ON TREATED SUNFLOWER SEED GERMINATION

Sunflower is one of the four most important oil crops and it is cultivated at 23million hectare (http://faostat.fao.org, 2009) in more than 70 countries all over theworld (de Rodrigez et al., 2002; Šimić et al., 2008). Sunflower is the most important oil crop in Serbia and it is cultivated at 146,000 to 201,000 ha (http://webrzs.stat.gov.rs/axd/poljoprivreda, 2009). Sunflowers sown areas dependon year conditions, yield and economic position of this important crop (Miklič etal., 2004). High yield requires good hybrid, optimal technical measures, irrigation andseed of high quality (Milošević et al., 1996). Indicators of seed vitality, germination energy and sprouting in field conditions are determinate number ofplant per acres – one of three basic yield components. Seed quality affects speedand equable sprouting as well as the initial plant growth (Crnobarac, 1992).
