Seedbed and moisture availability determine safe sites for early Thuja occidentalis (Cupressaceae) regeneration.
Regeneration of many late-successional tree species depends on specialized safe sites. The primary objective was to investigate the roles of seedbed and moisture retention as dimensions of safe sites for the early regeneration of drought-sensitive northern white cedar (Thuja occidentalis). We hypothesized that rates of germination, survival, and growth of T. occidentalis are unlikely to differ ...
متن کاملComparing the Importance of Seedbed and Canopy Type in the Restoration of Upland Thuja occidentalis Forests of Northeastern Minnesota
In cold-temperate ecosystems of the upper Great Lakes Region, evergreen conifer-dominated forests were once common. As a result of past management practices, early-successional deciduous forests now dominate the landscape. Embedded in this matrix are stands of shade-tolerant conifers, including Thuja occidentalis . For the past several decades, large-scale T. occidentalis regeneration in remnan...
متن کاملDevelopment and multiplexed amplification of SSR markers for Thuja occidentalis (Cupressaceae) using shotgun pyrosequencing1
UNLABELLED PREMISE OF THE STUDY Sixteen novel, polymorphic, multiplexed microsatellite loci were developed for eastern white cedar (Thuja occidentalis) using simple sequence repeat (SSR)-enriched shotgun pyrosequencing. • METHODS AND RESULTS Sixteen loci were tested on a panel of 24 individuals from different populations. The number of observed alleles ranged from four to 22. Four sets of ...

متن کاملActivation of CD4-positive T cells by polysaccharide fractions isolated from the Cupressaceae Thuja occidentalis L. (Arborvitae).
Various mitogens have been described which act on different subpopulations of mouse and/or human peripheral lymphocytes. In recent years it has been mainly Japanese and German research teams that have isolated polysaccharide fractions with immunomodulative properties [1-3, 17]. In addition to fungal polysaccharides such as lentinan, schizophyllan, and PSK polysaccharide, which are basically in ...
