Shoot morphology and fate of buds in relation to crown location in young Fraxinus pennsylvanica var. subintegerrima
The relationships between shoot size and morphological patterns and crown location were investigated in 6-year-old green ash (Fraxinus pennsylvanica var. subintegerrima (Vahl) Fern.). In general, shoots were shorter in the ...
Response of red-osier dogwood (Cornus sericea) seedlings to NaCl during the onset of bud break
A greenhouse study was designed to test the response of red-osier dogwood (Cornus sericea L.) to NaCl during the onset of bud break. Seedlings treated with 50 mmol center dot L-1 NaCl for 32 d had lower shoot dry mass and ...
The effect of Frankia and Paxillus involutus on the performance of Alnus incana subsp rugosa in mine tailings
The purpose of this study was to determine whether symbiotic nitrogen-fixing bacteria and mycorrhizal fungi act synergistically to improve plant performance when grown on heavy metal mine tailings. Seedlings were inoculated ...
Crown development of a clone of Populus tremuloides exhibiting "crooked" architecture and a comparison with wild-type trees
Populus tremuloides Michx. (trembling aspen) is a tree species native to much of North America and is normally ascribed to the architectural model of Rauh, characterized by an excurrent crown structure with a central main ...
Artificial inoculation with Armillaria ostoyae in established conifers stressed by defoliation, planting, and thinning in Newfoundland
Armillaria ostoyae (Romagnesi) Herink causes root disease in conifers of the northern hemisphere. Pathogenicity tests of established conifer trees with A. ostoyae, has never been done in the boreal forest. Seven forest ...
