Provenance Differences in Conifer Seedling Variable Chlorophyll Fluorescence Responses Detected Using the Integrating Fluorometer
Vidaver, W.; Toivonen, P.; Brooke, R.; Lister, G.; Binder, W.
1989: Bismark, ND
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.
