Priming physiology and proteinase purification from resting jack pine seeds
(1989)
Pines constitute an important economic species for the lumber and paper
industries in the Boreal region (Galloway, 1986). Current seedling production,
dependent on the availability of high quality seed, may be considered ...
Variable ratio schedule control of dispersion in a patchy environment
(1989)
Current ecological theory suggests that foraging animals are controlled by the distribution and abundance of food resources. Contemporary ecological research focuses on optimizing resources through the maximization of ...
Germination in pea seeds : proteolytic enzyme activity and electron microscopy
(1989)
This study was undertaken with two primary objectives in mind. The first objective was to isolate several pea seed hydrolases present during early seed germination. The second objective was to perform an ultrastructural ...
Effects of resistance training on selected physiological parameters
(1989)
The literature presents contradictory statements concerning
the effectiveness of free weights, isokinetic devices and
plyometric exercises on the development of lower extremity power,
and lean body mass {Coyle, Feiring, ...
Glyphosate herbicide for the control of aspen in a white spruce plantation in Manitoba
(1989)
Three experimental herbicide trials were established within a
white spruce plantation located in the Porcupine Provincial Forest of
the Mixedwood Section (B.18a) (Rowe 1972) of western Manitoba. The
trials were as ...
Establishment and early growth of black spruce (Picea mariana [Mill.] B.S.P.) in relation to selected nursery lifting and storage practices
(1989)
Problems associated with the establishment and early growth of overwinter frozen stored black
spruce {Picea mariana [Mill.] B.S.P.) seedlings led to research on the effects of selected nursery lifting and
storage practices ...
Constraints on the formation of depositional placer accumulations in coarse alluvial braided river systems
(1989)
Placer accumulations are formed by the preferential sedimentation of heavy
minerals from the general population of detritus being transported by a fluid. The depth,
velocity, and grain size conditions under which placers ...
Attempts to differentiate elaphostrongyline larvae (Nematoda : Protostrongylidae) using guinea pigs (Cavia porcellus) as alternate hosts
(1989)
First-and third-stage larvae of Parelaphostrongylus tenuis, P. andersoni
and Elaphostrongylus cervi could not be distinguished morphometrically. Third-stage
larvae of P. tenuis did develop into recognizable adults ...
Culture specific MMPI norms for a sample of Northern Ontario Indians
(1989)
The most recent controversy to arise in the area of ethnic
exceptions to normative data in the use of the MMPI centers on
the establishment of minority norms. Significant general profile
and specific scale elevations ...
Tachistoscopic study of reading related operations in average readers and those experiencing difficulty
(1989)
Thirty elementary school children were classified
into equal groups of poor and average readers. In a
series of four experiments, subjects were requested to
provide vocal responses to tachistoscopically presented
stimuli ...
