The ecology of germination and reproduction of less frequent and vanishing species of Czechoslovak flora
- 7 Downloads
The ripened seeds show no marked dormancy and germinate within wide limits of temperature, where the temperatures of 6–10/25°C represent the optimum. 18 months old seeds germinated at the temperature of 10/25°C by 69% 13 year old seeds did not germinate. This annual winter species reproduces only in the generative way, the seeds sown in the middle of October 1987 and 1988 sprouted at the end of October, and the seedlings with 1–2 pairs of true leaves survived successfully the winter.
