In forest soils it has been shown that the seeds of some species can survive entire forest rotations (Granstrom, 1988) but others only survive for a few decades (Hill and Stevens, 1981).

Björn Rasch,Wilhelm Hofmann,Malte Friese,Ewald Naumannin common with the soils of most other vegetation types, those of woodlands also contain viable seeds (Roberts, 1981;Leck .., 1989). The density and species composition of soil seed banks depend on the rate at which seeds enter and are lost from the soil. In frequently disturbed habitats, seed banksCosmopolitan 发表于 2025-3-24 19:51:22
