The Effects of Temperature and Gibberellic Acid on Germination of Eranthis hyemalis (L.) Salisb. seeds


Abstract: In this study, the effects of different temperatures and exogenous gibberellic acid (GA 3) treatments on the germination of Eranthis hyemalis (L.) Salisb. seeds were studied. E. hyemalis seeds were exposed to the germination process at +4 °C and +23 °C in distilled water (control) and 0.10 , 5 and 10 mM concentrations of gibberellic acid (GA 3). While no germination was observed at +23 °C either in the control group or in the germination dishes where GA 3 was applied, at +4 °C, both in the control group (except for the 60th and 75th days) and with the all concentrations of GA 3 , seed germination was observed. At +4 °C, all concentrations of GA 3 caused germination one month before germination occurred in to the control group.

Keywords: Eranthis hyemalis, germination, gibberellic acid (GA 3), temperature.
