Salinity and waterlogging tolerance of some populations of Melaleuca ericifolia Smith.

This article examines the salinity and waterlogging tolerance of some populations of Melaleuca ericifolia Smith. Seed germination of Melaleuca ericifolia is delayed by submergence in water but the final percentage germination after removing seeds from water is unaffected; some seeds will germinate and the cotyledons emerge whilst submerged. Seedling growth may be increased by waterlogging conditions and the degree of response differs for different seed sources. Inundation stimulates root growth and new roots are thick and aerenchymatous.
