Hypoxylon Infection Not Greatly Influenced By Sex Of Aspen Trees, G.W. Anderson
Hypoxylon Infection Not Greatly Influenced By Sex Of Aspen Trees, G.W. Anderson
Aspen Bibliography
The results of a survey taken in northern Minnesota indicate that the occurrence of Hypoxylon canker on aspen has little or no correlation with the sex of the tree. This survey was made during the flowering seasons of 1957 and 1958.
The Growth And Yield Of Aspen [Populus Tremuloides] In Saskatchewan, C. L. Kirby, W. S. Bailey, J. G. Gilmour
The Growth And Yield Of Aspen [Populus Tremuloides] In Saskatchewan, C. L. Kirby, W. S. Bailey, J. G. Gilmour
Aspen Bibliography
This report is a summary of all studies carried out by the Saskatchewan Forestry Branch in hardwood stands. Aspen, the principal component of the hardwood stands, is the most abundant tree species by both volume and area in Saskatchewan and is most difficult to analyze. This report presents conclusions from which further studies can be conducted. It is hoped that in the future closer correlation with site-types may be made as it is difficult and probably not desirable to make further generalization on a province-wide basis. However, before detailed questions could be studies it was necessary to have a picture …

The Treatment Of Decayed Wood From Dead Trembling Aspen Trees For Growth-Ring Analysis, Arthur W. Ghent
The Treatment Of Decayed Wood From Dead Trembling Aspen Trees For Growth-Ring Analysis, Arthur W. Ghent
Aspen Bibliography
This paper elaborates certain procedures briefly outlined in an earlier article. Although dry wood from dead trembling aspen has been found best suited to growth-ring analysis, in its absence use has been made of water-saturated wood from the underside of fallen trunks. A technique of wax impregnation, adaptable to wood in both early and advanced stages of decay, is described. Rapid impregnation with near-boiling wax is sufficient to facilitate transverse sectioning of relatively sound wood; advanced decays require a slower impregnation with cooler paraffin. Hot xylol is used to remove the wax and flatten the section. Successive, overlapped sections provide …
