Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration
(2009)To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera ... -
Effects of container volume and shape on the growth of black spruce (Picea mariana (Mill.) B.S.P.) seedlings
(1984)The objective of this thesis was to evaluate the growth of black spruce seedlings in containers with four soil volumes (45, 90, 180, 360 cm3) and at three diameter/depth shapes (1:2, 1:3, 1:4). Seedling height, root collar ... -
Effects of seed sources and fungi on ectomycorrhizal formation and growth of containerized tamarack seedlings
(1985)The objectives of this study were to investigate the host specificity of mycorrhizal fungi to tamarack (Larix laricina (Du Roi) K. Koch.) in pure culture synthesis and to examine the effects of seed sources and fungal ... -
Evaluation of a mini-container accelerated transplant system : the black spruce winter crop
(1986)The effects of four factors on nine attributes of black spruce (Picea mariana (Mill) B. S. P.) seedlings were investigated. The seedlings were produced under an accelerated transplant system that used a 6 ml Castle ... -
Evaluation of a mini-container, accelerated transplant system : the black spruce summer crop
(1986)The production of black spruce ( Picea mariana (Mill.) B.S.P.) bare root stock in Ontario nurseries presents two main problems. First, seedlings at the end of the first growing season are small, and thus susceptible to ... -
Interactive effects of soil temperature and resource availability on physiological and growth responses of white birch (Betula papyrifera) seedlings to atmospheric carbon dioxide elevation
(2009)Predicting the impacts of future high atmospheric CO2 concentration, [CO2], on the physiology and growth of boreal forests is complicated by interactions of CO2 with other environmental conditions. Two-factor CO2 x environment ... -
Root pruning, wrenching and overwinter cold storage : effects on the morphological and physiological condition of transplant Picea glauca [Moench] Voss nursery stock
(1984)The objectives of this thesis were to; 1) evaluate the effect of a single early spring root pruning followed by a series of five root wrenching treatments at three week intervals on the morphological condition of rising ...
