Some effects of different forest litters on seed germination and growth

Germination and growth of 12 native herbs, shrubs, and trees were followed in five litter components characteristic of successional stages of the northeastern Minnesota forest. Various litter components stimulated or inhibited seed germination and seedling growth of some species. Germination and growth were not always similarly affected, suggesting that different factors may be involved. Inhibition and lack of inhibition of some species on certain litter components correlate with natural habitat preferences of these species and the nature of the litter in these habitats. This information can be of use in improving results of seeding for site reclamation and reforestation.
