Abstract

To investigate the effects of seed priming in Linum usitatissimum L. on germination characteristics and yield, experiments were conducted in the laboratory conditions. In laboratory a completely randomized design in factorial layout with 11 treatments (Poly Ethylene Glycol -5, -10 and -15 bar, gibberellin in 200, 400 and 600 ppm, KNO3 in 200, 400 and 600 ppm concentrations, hydro-priming and control) in ranges of temperatures (15/25, 20/25, 25/25 and 30/25  °C -day/night)  with 4 replication. The results showed that priming had a significant effects on seed germination characters. PEG treats had the most negative effects on germination characters. The most of seed vigour, percentage and ratio of germination, length of radicle and length of plumule amounts were made by KNO3 (200 ppm) and gibberellin (400 ppm) under temperature range of 20/25 ° C (day/night). It seems this influence made by the beneficial effects of potassium nitrate in growth and plant maintenance and effectiveness of gibberellin in cell growth and photosynthesis.
