The control of filbert (Corylus Avellana L.) suckers by means
of herbicides was investigated in three phases during 1968 and 1969.
(1) Screening trials, on canned filbert trees in the greenhouse, to
determine the effectiveness of various herbicides and concentrations
in controlling vegetative growth. (2) A summary experiment in the...
Research was conducted in the field and greenhouse to determine if a
kaolinite-based particle film, Surround®, would reduce colonization and early season
feeding damage in cucurbits by the Western Striped Cucumber Beetle, Acalymma
trivitattum (Mannerheim). Greenhouse studies were designed to determine effect of
particle film on cucumber dry weight production...
Mortality from Armillaria root rot is a major concern of forest management. Field experiments were conducted in Minnesota to evaluate interspecific differential susceptibility and to assess whether density or species composition, specifically the proportion of conifers in a plot, influences seedling mortality from Armillaria spp. Seedlings of 10 tree species...
There is concern that the conifer component of mixed conifer-deciduous forests in the Great Lakes region is on the decline, possibly the result of insufficient conifer regeneration. Limitations on conifer regeneration that occur during the first 18 months of seedling emergence and establishment were examined for Abies balsamea (L.) Mill....
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
Letters included were sent to request increased funding for the Titles I and II of the Tribally Controlled College or University Assistance Act. Another letter to the director of Indian Health Services expresses concern over funding delays to the tribes for diabetes.
