ecotypic variation of black spruce in northwestern ontario
abstract
the success of reforestation can be improved by selecting the appropriate seed source
for the site type. however, not much is known about the differences in using upland
versus lowland black spruce seed sources when making seed transfer decisions. a black
spruce provenance test consisting of 50 seed sources from across northwestern ontario
was analyzed to determine if adaptive divergence of provenances originating from
different soil types was evident. differences in height and diameter of black spruce
provenances planted at the 25th side road tree farm near thunder bay, ontario were
examined. soil categories were created based on the northwestern ontario forest
ecosystem classification (fec) program. one-way and two-way anovas were run for
each of the measured variables. the results suggest an absence of ecotypic variation
concerning soil types in black spruce.
