An Examination Of The Leaf Quaking Adaptation And Stomatal Distribution In Populus-Tremuloides, J.W. Rushin, J.E. Anderson
An Examination Of The Leaf Quaking Adaptation And Stomatal Distribution In Populus-Tremuloides, J.W. Rushin, J.E. Anderson
Aspen Bibliography
The leaves of quaking aspen (Populus tremuloides Michx.) have a flattened petiole that allows them to quake (oscillate and roll) under low wind velocities. It was hypothesized that this adaptation might enable the plant to respond to windy conditions that would increase transpirational losses. No effects of wind with or without leaf quaking on stomatal resistance were observed under controlled conditions in the field. If wind and leaf quaking affect stomatal resistance, such effects must be small in comparison to those caused by other factors such as leaf water potential and ambient humidity.
Aspen leaves are hypostomatal with stomata …

Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Aspen Bibliography
A recently discovered, widely distributed canker disease of aspen and other poplars throughout the Rocky Mountain region is described. Inoculations with ascospore and conidial isolates of Cryptosphaeria populina show the fungus is capable of causing branch, sprout, and sapling mortality, trunk cankers, and the discoloration and decay of aspen stems previously associated with its imperfect stage, Libertella sp. The greatest average canker elongation 50 mo after September inoculations was 33.5 cm with sapwood decay and discoloration extending to 401 cm. The fungus caused an average weight loss of 13.5% in bark, 27.0% in sapwood, and 19.1% in heartwood blocks. Incidence …

Utilization Of Aspen Populus-Tremuloides Trees As A Ruminant Feed Component, M. Singh, L.D. Kamstra
Utilization Of Aspen Populus-Tremuloides Trees As A Ruminant Feed Component, M. Singh, L.D. Kamstra
Aspen Bibliography
When traditional roughages are in short supply or high in price, other fibrous feed sources for ruminants should be considered if available at a competitive price. One such fibrous material shown to have potential as a ruminant feed is the aspen tree (Populus tremuloides Michx.) harvested in its entire form to include bark, leaves and trunk. The aspen tree is the most widespread tree species in North America and the least utilized. Estimates exceed 6 million acres of mature trees in an area which would include the Black Hills (58,000 acres), the Great Lakes region and the Rocky …

Estimating Plant Biomass For Undergrowth Species Of Northeastern Minnesota Forest Communities, L.F. Ohmann, D.F. Grigal, L.L. Rogers
Aspen Bibliography
Knowledge of the plant biomass comprising a forest community is important to many aspects of multiple-use management. Direct measurement of biomass, however, is expensive and time-consuming to under-take each time biomass information would be useful. Fortunately, other measurements that can be made in the field less expensively or more easily can be used for estimating biomass.
Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Aspen Bibliography
The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting.

Present Utilization Of Species In The Boreal Mixedwood Forests In Ontario: Industrial Perspective, M.A. Opper
Aspen Bibliography
Yields per unit area are higher from boreal mixedwood stands than from black spruce stands. In addition, mixedwood stands are attractive for the logging industry because of high-value products, year-round logging, and economies in road access. Major unresolved problems in boreal mixedwood stands are lack of markets for hardwood species and increased hardwood components and balsam fir in succeeding stands.
Ecological Succession In Aspen And Its Consequences On Multiple Use Values, Roy O. Harniss
Ecological Succession In Aspen And Its Consequences On Multiple Use Values, Roy O. Harniss
Aspen Bibliography
Aspen can be categorized as (1) seral-- successional to conifer, (2) stable--regenerates to aspen, or (3) decadent--successional to brush, forbs, or grasses. Succession to conifers reduces understory production, plant and wildlife diversity, water yields, and aesthetic values while it increases timber values. Stable aspen stands, except possibly for timber values, maintain these multiple use values if grazing is not excessive. In decadent aspen stands all of the multiple use values except water are reduced. Management expectations and returns for multiple use values would depend on the successional status of the aspen.
