Genetic variation in physiology and growth under ambient and elevated CO2 concentrations in four provenances of Populus tremuloides from Northwestern Ontario
Trembling aspen (Populus tremuloides Michx.) is the most widely distributed and probably most genetically varied woody species in North America. Four provenances of trembling aspen seedlings from northwestern Ontario ...
Physiological and growth responses of eleven Ontario provenances of one-year old Picea glauca seedlings to elevated CO2 concentrations
To study the physiological and growth responses of eleven Ontario provenances of white spruce [Picea glauca (Moench) Voss] to elevated atmospheric CO2 concentrations, one-year old seedlings were grown in three greenhouses ...
Effects of elevated carbon dioxide concentration and light on biomass morphology and physiology of black spruce and white spruce seedlings
Carbon dioxide concentration and light interactions influence competition among boreal tree species, though little is known about the exact effects. The interactive effects of [CO 2 ] and light on growth, biomass production, ...
