The effect of cytokinins on flax seed germination at low temperature

Irena Niedźwiedź-Siegień, Sylwia Bukłaha

Abstract


Germination of flax seeds (Linum usitatissimum L., cv. Szafir) at 5oC was enhanced by continuous white light, gibberellin A3 (GA3), kinetin and benzylaminopurine. GA3 and kinetin at physiological concentrations (10-8-10-6 M) improved significantly germination in darkness. Stimulatory effect of benzylaminopurine was visible only in the light. Almost no effect of zeatin and isopentenyladenine (2iP) on germination was observed. Possible causes of this differences were suggested.
