Description
| - Temperature is a limiting factor for plant reproduction under harsh conditions. Using an infrared camera, we studied temperature distribution in three early flowering light-coloured species of markedly different morphology. The influence of (temperature of the ambient air, temperature of the ground and irradiance on the temperature of the flowers and inflorescences was evaluated. White petals and yellow centres of sun tracking Anemone nemorosa were on average 1.6 and 3.4 °C warmer than the ambient air, respectively. The surface temperature of the sun lit yellow discs of Bellis perennis was on average 7.4 °C warmer than the ambient air. Direct solar light was responsible for large temperature differences between the discs and the marginal ray flowers. Bell-shaped flowers of Galanthus nivalis bent to the ground were on average 2.7 °C cooler than the surrounding air. The temperature relations of the different reproductive organs to the studied environmental factors are discussed.
