Provenance Differences in Conifer Seedling Variable Chlorophyll Fluorescence Responses Detected Using the Integrating Fluorometer

Differing from white spruce, Douglas -fir seedlings showed no day length-dependent inactivation of photosynthetic photochemistry. Seedlings of both species show reversible inactivation in response to temperature or drought stress. Provenance differences were observed in the responses of coastal Douglas -fir: high elevation seedlings appeared to be more sensitive to declining temperatures than low elevation seedlings.
