Seed biology, reproductive phenology and conservation of Cedrus brevifolia, a threatened endemic tree of Cyprus
Cone and seed morphometric characteristics, seed germination behaviour and seed viability during storage were studied in Cedrus brevifolia, a threatened endemic forest tree of Cyprus. The number of seeds per cone, seed mass and number of cotyledons per seed followed normal distributions. Seeds germinated promptly in darkness at 20°C after eight weeks of prechilling at 5°C. Seed germination under conditions simulating those prevailing in the field from December to May in Cyprus (wet period) is manifested in early spring (February-March). Far red light does not inhibit seed germination, indicating seedling emergence in the field irrespective of canopy light conditions. Seed longevity was extended by low moisture content and low temperature. Therefore, the data obtained on seed germination and preservation of seed viability contribute to both the understanding of the germination mechanisms in the field and the proper management (in situ and ex situ) of Cyprian cedar.
