Influences of sweet-fern on germination, survival, and early growth of red pine

摘要

Concentrated water extracts from foliage and from roots of sweet-fern were used as moistening media in laboratory tests on germination and survival of red pine. Neither inhibited germination, but both affected survival adversely. In tests simulating field conditions germination, survival, and growth were judged to be more closely related to moisture than to the presence of sweet-fern.
