| Abstract: | Oregano and sweet basil were grown in phytotron cabinets at 18/12°, 24/12° and 30/12°C (day/night) in either 10-or 16-h photoperiods. Only temperature had a positive influence on plant height in both species. The fresh yield was significantly influenced by temperature and daylength in all the three harvests examined for both species. The correlation between these results and field behaviour in different regions is discussed. The optimum temperature for the germination of oregano was a day/night regime of 24/19°C; sweet basil was less sensitive and germinated well at temperature regimes between 18/13° and 30/25°C. |
