Determining Impediments to Gene Flow in a Natural Population of Cornus florida L. Cornaceae, Using Integrative Landscape Genetic Techniques
… flow in the insect pollinated understory tree, Cornus florida L., by combining GIS and landscape genetic techniques (Least Cost Path Analysis, Circuit Theory, and Conditional Genetic Distance). Traditional population genetic analysis indicated pair-wise relatedness was significantly correlated …

Abiotic stressors in the dogwood anthracnose complex
… (DA) caused by Discula destructiva, on Cornus florida, the flowering dogwood. Seedlings were subjected to acidic fog episodes at pHs 2.5, 3.5, 4.5, and 5.5, using a simulated acidic rain solution. Leaf discs from these and non-treated plants were examined by scanning electron microscopy …

Effects of Soil Fungi on Tree Seedling Establishment in a Southeastern Coastal Plain Forest
… of South Carolina. Seedlings of Quercus alba, Cornus florida and Pinus taeda were planted in the understory of two forest types -naturally regenerated hardwood and planted pine. Fungal species composition and biomass were experimentally manipulated with a treatment of the fungicide captan. In …

Factors limiting the regeneration of large-seeded hardwoods in the Upper Coastal Plain of South Carolina
… one-year old bare root Quercus alba L. and Cornus florida L. seedlings in pine plantation understories and adjacent clearcuts. We hypothesized that soil moisture, light, and leaf and stem herbivory would have relatively strong effects on growth and survival during the first two years after …

Earthworms in the Urban Environment: Can Population Augmentation Improve Urban Soil Properties?
… soil tolerances were planted (Acer rubrum and Cornus florida). We measured soil physical and chemical properties along with earthworm survival and soil respiration. Earthworm inoculation did not succeed in improving bulk density or increasing soil organic matter, yet it was successful in …

Identifying floral hosts of cerambycid beetles using palynology
… frass of Callimoxys sanguinicollis (Olivier) on Cornus drummondii C.A.Mey. (Cornaceae) and Molorchus bimaculatus Say on Cornus florida L. Next, I described the pollen taxa in the frass of palynivorous beetles collecting in traps and at lights by calculating the mean abundance and proportions of …

Influence of Lime and Micronutrient Amendments on Growth of Containerized Landscape Trees Grown in Pine Bark
… (sugar maple), Cercis canadensis (redbud), Cornus florida (flowering dogwood), Cornus kousa (kousa dogwood), Koelreuteria paniculata (golden-rain tree), Magnolia x soulangiana (magnolia), Nyssa sylvatica (blackgum), and Quercus palustris (pin oak)] were grown from seed in two pine barks: pH …

Growth and Physiology of Several Urban Tree Species in Soils Disturbed by Construction Fill or Compaction
… soil strength. Seedlings of flowering dogwood (Cornus florida), a species intolerant of inundation, and silver maple (Acer saccharinum), a bottomland species, were grown in a loam soil maintained at various combinations of soil strength and soil matric potential. In moderately compacted soil …

Leishmanicidal, anti-inflammatory and anti-obesity properties of natural products from common medicinal and edible plants.
… isolated from Cichorium intybus L. (Asteraceae), Cornus florida L. (Cornaceae), Eryngium foetidum L. (Apiaceae), which have been used traditionally as antiparasitic remedies. The roots of C. intybus (chicory) yielded four sesquiterpene lactones: (1) 11(S),13-dihydrolactucopicrin, (2) …

The available nutrients in selected deer browse species growing on different soils
… year’s growth of twigs from flowering dogwood (Cornus florida), black locust (Robina pseudoacacia), and red maple (Acer rubrum) were collected at two-month intervals on study areas whose soils had arisen from either Brallier, Clinton, Huntersville chert, or Martinsburg shale geological …
