Review Of Silvicultural Research: White Spruce And Trembling Aspen Cover Types, Mixedwood Forest Section, Boreal Forest Region, Alberta-Saskatchewan-Manitoba, J. M. Jarvis, G. A. Steneker, R. M. Waldron, J. C. Lees

Aspen Bibliography

The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …

Cacodylic Acid As A Silvicide, Maurice W. Day

Aspen Bibliography

This report deals with the effectiveness of cacodylic acid (dimethylarsenic acid) as a silvicide for undesirable trees. Cacodylic acid has been used successfully as an herbicide for the destruction of grasses and weeds. Experimental work with this material was begun during the 1963 field season, and continued during 1964, to permit complete evaluation of the results. It appears that cacodylic acid has considerable potential as a silvicide.

Bee Farming : Maintaining Productive Stock, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 4

EVERY bee hive must be a productive unit, headed by a young vigorous queen, to to make sure of the greatest possible return from capital invested in the commercial apiary.

Grasshoppers And Locusts In Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.

The Romney Marsh, J A. Mallett

Journal of the Department of Agriculture, Western Australia, Series 4

THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.

Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Some Aspects Of Regeneration Silviculture In Spruce-Aspen Stands In Alberta, L. A. Smithers

Aspen Bibliography

Surveys of spruce-aspen stands in Northern Alberta have shown that natural regeneration of white spruce is generally a failure on areas which have been logged but not burned (Candy 1951).

Field Guide To Aid In Recognition Of Natural Triploid Aspen, Philip N. Joranson, Dean W. Einspahr, J P. Van Buijtenen

Aspen Bibliography

Swedish experience with the genetic improvement of the European aspen (Populus tremula L.), a species which is closely kin to our North American quaking aspen (P. tremuloides Michx.), suggests that the rate of volume increment and the length of fiber tracheids might both be increased in North American aspen by finding or producing trees which possess a triple set, rather than the usual double set, of "chromosomes". Chromosomes (Figure 1) are found within and inner region--the nucleus--of each of the millions of cells formed during the growth of a tree.
