Descripción
The germination requirements and the cryopreservation tolerance of Tuberaria major (Cistaceae) seeds, an endangered plant species endemic from the Algarve region (South of Portugal) were studied. The final germination percentage of untreated seeds was very low (less than 2%) and was significantly improved by heat treatments (maximum of 54%). No significant differences were observed among the germination percentages reached by seeds submitted to boiling water or dry heat (100°C for different periods: 15, 30 and 60 min). Moreover, the temperature regime did not affect the final germination percentage. Cryopreservation did not affect the germination rate in comparison with the control, although the heat treatment was still necessary after cryopreservation. In conclusion, it was observed that heat stimulated germination of T. major seeds and cryopreservation could provide a method for long-term storage of germplasm of this endangered species.
