vegetative and sexual phenology, reproductive dynamics and bud differentiation in a clonal seed orchard of white and black spruce
(1981)to evaluate the importance of phenology and strobilus production in a clonal seed orchard of white and black spruce, 14 clones of each species represented by 4 ramets each, were selected from the mattawin seed orchard. ... -

synthetic studies on chaksine
(1981)this thesis is concerned with the studies in the synthesis of a monoterpenoid alkaloid, chaksine. ethyl 2-n~butyl-4-bromoacetoacetate (11) was treated with sodium azide to give ethyl 2-n-butyl-4-azidoacetoacetate (12), ... -
photosynthetic efficiency of frozen-stored picea glauca seedlings in relation to root pruning, root growth, and shoot moisture stress / by s. j. colombo. --
(1981)this study examines the influence of duration of frozen storage (-2 c) and root pruning on photosynthetic efficiency, shoot moisture stress and root growth of white spruce (picea glauca (moench) voss) seedlings planted ... -
crown dynamics in pinus resinosa ait. : analysis and stochastic description of branch production, branch extension growth and foliage dry weight---branch length relationships
(1981)the development of the crown structure of pinus resinosa ait. was analysed in terms of three component processes of tree growth: the number of first order branches per whorl within the crown, the annual extension increments ... -
arguesian lattices of order 3
(1981)since the mid 19th century it has been known that every desarguean projective’ plane is coordinatizable over a division ring. this coordinatization procedure was used by von neumann [9] to show that every complemented ... -
aspects of the reproductive biology of clintonia borealis (ait.) raf.
(1980)the rhizome of clintonia borealis tait.) raf, was shown to store large quantities of total nonstructural carbohydrates up until fall dormancy and to draw upon these reserves during the spring growth period, however the ... -
synthesis and biodegradation of model compounds related to hydrocarbon-type dielectric fluids
(1981)uniroyal pa0-20e, an oligomer of 1-octene, is a dielectric fluid proposed as a replacement for polychlorinated biphenyls. no studies on its biodegradation have been reported in the literature to date. this thesis ... -
indices of branch contribution to bole growth in pinus resinosa ait.
(1982)the contribution of individual branches to the current annual xylem increment of the main stem of six young red pine (pinus resinosa ait.) was investigated. logical estimates of branch productivity including: branch ... -
ten-year growth response of 45-year old pinus banksiana lamb. to urea fertilization and low thinning
(1982)the objectives of this investigation were 1) to examine the duration and pattern of jack pine growth response to urea fertilization and low thinning, and 2) to examine methods commonly used in the measurement of ... -
post logging succession and vegetation management with hexazinone herbicide in picea glauca (moench) voss-populus tremuloides michx. forest
(1981)the objectives were: to review the successional behaviour of white spruce (picea glauca (moench) voss) - trembling aspen (populus tremuloides michxt) stands in the literature, to conduct field studies of the successional ... -
application of a sequential partial extraction procedure to investigate uranium, copper, zinc, iron and manganese partitioning in recent lake, stream and bog sediments, northern saskatchewan / by douglas andrew warren lehto. --
(1981)sequential partial extractions show that partitioning of uranium, copper, zinc, iron and manganese into lake, stream and bog sediments are affected by the type and abundance of component fractions present in sediments ...
