The effects of exposure to different environments on the viability of Protea neriifolia seeds


, : The effects of exposure to different environments on the viability of Protea neriifolia seeds. South African Journal of Botany 57(4): 226-228

The number of seedlings recruited per parent plant of serotinous Proteaceae varies seasonally from low after winter to high after autumn fires. Loss of seed viability or seed decay due to prolonged exposure in the post-fire environment (winter fires) may explain part of this variation in seedling recruitment. Seeds of Protea neriifolia were harvested in October 1986 in SW Cape, South Africa.
