| Popis: |
Fresh seeds of the endangered Hakea dohertyi Haegi (Proteaceae) germinated at 15°C (with 12 hour light) within 14 days. At higher temperatures (20°, 25°C) seeds were slower to germinate. After 28 days only 5% of seeds germinated at 30°C, but when moved to 15°C, close to 100% of seeds germinated within 14 days. Having established optimum germination conditions, the effects of ex situ storage conditions and duration were examined. Storage at low moisture content appeared to have little effect on the germinability of Hakea dohertyi seeds and this species can be considered orthodox in that respect. Seeds stored at 4.5 or 9% moisture content, 5 or -20°C and tested after 1 and 7 years of storage achieved close to 100% germination. Issues relating to the in situ and ex situ conservation of Hakea dohertyi are discussed. |
