| Abstract:
To investigate the effects of temperature and light on germination of Lavandula stoechas seeds, were incubation at 5, 10, 15, 20, 25, 30 and 35oC and dark and light (12hr) conditions for 25 days was implemented. Seeds incubated 5, 30 and 35oC, under light or dark failed to germinate. Increased seed germination was observed at 10, 15 and 20oC under light or dark conditions while seeds incubated at 25oC in darkness showed maximum germination 37.5%. Germination capacity at 10oC under light was maximised (96.2%) and decreased to 76.2% at higher incubation temperature up to 25oC. Seeds incubated at light, germinated earlier compared to dark, with the exception of 25oC at which the onset of germination showed a lag time of 5 and 4 days, for light and dark, respectively. It is concluded that L. stoechas seeds germinate best at 15+5oC under 12hr photoperiod conditions. | |
