Germinative behaviour of Acacia dealbata Link, Ailanthus altissima (Mill.) Swingle and Robinia pseudoacacia L. in relation to fire and exploration of the regenerative niche of native species for the control of invaders

Invasion of forest ecosystems by invader plants and fires are two the most serious environmental problems in world. Climate change is believed to strongly influence these processes, invasibility invasive alien (IAPs) likely enhance landscape degradation. Therefore, it urgent study germinative behaviour relation fire detect possible barrier species IAPs among native species. Tree usually damaging group plants. Acacia dealbata Link, Ailanthus altissima (Mill.) Swingle Robinia pseudoacacia L. 3 very exotic trees Europe many other parts germination (germination percentage, viability pregermination, postgermination rate) three was experimentally studied against different products associated with (heat, smoke, ash charcoal). The A. R. stimulated heat, while charcoal barely changed control values. None factors altissima. Very high temperatures inhibited seed seeds faster than that seeds.

For this purpose based on extensive bibliographic revision, regenerative niches (germination, seedling growth adult height) were compared those European identify candidates for between Among characteristics their niche suitable successfully compete tall shrub such as Adenocarpus lainzii (Castrov.)
