Conteúdo: |
Cucumis anguria present dark germinating seeds at 25%C. Seeds without the tegument are photosensitive germinating better in darkness than under continuous white litgh. However, pre-incubation at 40°C for 48 hours allows the seeds to germinate under comtinuous white ligth and the incubation of naked seeds at-0.6MPa restored the ligth inhibition of seed germination. Our results suggest that the tegument interact with the phytochrome in the control of seed germination in part of the population of seed of C. anguria. |
