Long dry spells (sequences of dry days) are rare events, but they are important because they correlate significantly with the area burned during bad wildfire years. Previous attempts to model the frequency of dry spells have been successful for spells of short duration, but have failed for...
Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western CanadaDownload
This study contains a series of experiments to evaluate growth performance and survival of hybrid poplars (Populus spp.) and trembling aspen (Populus tremuloides Michx.) in boreal planting environments in western Canada. Ecophysiological traits related to drought resistance and winter survival...
An ecophysiological investigation of the jackpine woodland with reference to revegetation of mined sandsDownload
This project was conceived as a multidisciplinary integrated study to determine the physiological limits of native and non-native species to dry, nutrient-poor environmental conditions on a steep-sided sand dike and on sand piles. Only when the limits of survival are known for native and...
Effects of drought on Eleusine coracana (L.) Gaertn. (finger millet) and identification of microsatellite markersDownload
Finger millet (Eleusine coracana (L.) Gaertn.) is a crop with high nutritional profile cultivated mainly in developing countries. It is an allotetraploid (2n= 4x= 36 chromosomes), that belongs to the Poaceae family and has a genome size of 2509 Mbp. Drought is one amongst other abiotic stresses...
Variation in xylem structure and function has been extensively studied across different species with a wide taxonomic, geographical and ecological coverage. In contrast, our understanding of how xylem of a single species can adjust to different growing conditions remains limited. In this thesis,...
This thesis explores the influence of non-structural carbohydrates (NSC), seedling size, and root:shoot ratio (RSR) on jack pine (Pinus banksiana Lamb.) seedling performance under different drought intensities in a growth chamber and after outplanting on a reclamation site. NSC content, size, and...
Evaluating trembling aspen (Populus tremuloides Michx.) seedling stock characteristics in response to drought and out-planting on a reclamation siteDownload
Trembling aspen (Populus tremuloides Michx.) seedlings often display reduced growth, or transplant shock, following out-planting largely due to moisture constraints. This thesis explores the influence of seedling size (root volume), root to stem ratio (RSR) and non-structural carbohydrate (NSC)...
In this study, growth of seven hybrid poplar clones and one pure poplar clone was investigated in relation to leaf, shoot, and root physiology under field conditions. Clones included: Walker (24 - P. deltoides x P. xpetrowskyana), Assiniboine (25 - open pollinated Walker cv. Assiniboine),...
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....
Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigeraDownload
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...
