摘要: Some factors (gibberellic acid, ethanol, prechilling) affecting germination of seeds Linum album DC. were investigated. The objectives this experiment to determine the effects sulfuric gibberellic acid and on L. find an effective method for breaking its seed dormancy. Seeds collected in 2007 tested viability. tetrazolium chloride test showed be 95.1% viable, however was 0% indicating nearly 100% study investigate several methods dormancy improving species. Fourteen treatments (Sulfuric (98%, 15 30 sec), Sulfuric (75%, 15, 60 GA3 (1500, 2500, 3500 ppm, 48 h), GA 3 (3500 24 ethanol 12 (96%, 6, h)) used. (1500 (2500 h) increased 80, 92, 96 96%, respectively. Ethanol had no effect germination. Seed possible say that their sleeping period is endogenous. may both exogenous endogenous nature. Its broken by some with 3, being most effective. Effectiveness depend concentration compounds, appropriate treatment time duration.
