Hypoxylon Canker Incidence On Pruned And Unpruned Aspen, Michael E. Ostry, G.W. Anderson
Hypoxylon Canker Incidence On Pruned And Unpruned Aspen, Michael E. Ostry, G.W. Anderson
Aspen Bibliography
This sturdy was designed to measure the relation between the incidence of Hypoxylon canker, Hypoxylon mammatum Wahl. Mill., and the presence of branches on an aspen stem.
Phytoalexin Production By Aspen (Populus Tremuloides Michx.) In Response To Infection By Hypoxylon Mammatum (Wahl.) Mill. And Alternaria Spp, G. Flores, M. Hubbes
Phytoalexin Production By Aspen (Populus Tremuloides Michx.) In Response To Infection By Hypoxylon Mammatum (Wahl.) Mill. And Alternaria Spp, G. Flores, M. Hubbes
Aspen Bibliography
Freshly wounded stem sections of P. tremuloides Michx. produce phytoalexin when inoculated with mycelium of Hypoxylon mammatum (Wahl.) Mill., and Alternaria sp. These exudates are inhibitory against spore germination of these two fungi and, although inhibitory against mycelial growth of Alternaria sp., have no effect on the mycelial growth of H. mammatum. It was possible to correlate the amount of phytoalexin elicited by different strains with the inhibitory activity.
Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel
Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel
Aspen Bibliography
Vegetation and soils were sampled in adjacent 40-year-old stands of red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), white spruce (Picea glauca (Moench.) Voss), and aspen (Populus tremuloides Michx., P. grandidentata Michx.) on a very fine sandy loam soil in north-central Minnesota. Total tree biomass was greatest for red pine followed by by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and …

Spatial Pattern And Population Dynamics Of Populus-Tremuloides In A Saskatchewan Canada Aspen Grove, O.W. Archibold, M.R. Wilson
Aspen Bibliography
The spatial pattern of nine 5-yr age-classes of trees in a grove of Trembling Aspen (Populus tremuloides) was studied by applying nearest-neighbor analysis to a transect.
