Özet:

 

To investigate the possible use of wild sunflower species (Helianthus spp.) with cultural varieties at classical breeding studies and to overcome the seed dormancy and germination problems encountered at germination stage in seed, the effect of mechanical damage to the seed on to emergence rate and emergence force was determined. The study was conducted at Uludağ University, Agricultural Faculty, Field Crops Department, Plant Tissue Culture Laboratory and green house in 2014. Seeds of wild sunflower genotypes were obtained from 3 different sources (USDA-USA, Germany, Canada). The seeds imbedded in water one day were scratched carefully from embryo sites and then placed into viol containing 1 : 1 peat: soil mixture (v/v) at 24 ± 2oC in 16h/8 h (light/dark) in the growth chamber. Emergence rate and emergence force values were taken after 10 and 17 days from seeding. Emergence rate and emergence force values varied from 0 - 100% depended on the genotype. The highest emergence rate values (100%) were obtained from genotypes numbered as 4, 17, 20, 24, 37, 59 while genotypes numbered as 31, 32, 33, 38, 39, 40, 41, 46, 47, 48, 49, 51, 52, 55 did not have emergence rate values (0%). The highest emergence force values (100%) were obtained from genotypes numbered as 4, 17, 19, 20, 24, 37, 59 while genotypes numbered as 31, 32, 33, 38, 39, 40, 46, 48, 49, 51, 52, 55 did not have emergence force values (0%).
