Ecophysiological Mechanisms Underlying Aspen to Conifer Succession

W. John Calder ScholarsArchive (Brigham Young University) 2009

Other claims from this paper (11)

Observation Aspen was more sensitive to light and soil changes than subalpine fir.
Intervention effect Reduced light lowered aspen height, biomass, photosynthesis and defense compound production.
Intervention effect Conifer-influenced soil lowered aspen height, biomass, photosynthesis and defense compound production.
Intervention effect Low light reduced subalpine fir photosynthesis, biomass and root:shoot ratio.
Intervention effect Subalpine fir physiology and growth did not differ between soil types.
Association Conifers established closer to aspen as conifer canopy density increased.
Association Closer canopy proximity was associated with increased mortality of both aspen and subalpine fir.
Intervention effect Twenty minutes of smoke exposure reduced photosynthetic capacity by more than 50% in five of six tree species.
Mechanism Photosynthesis impairment under smoke reflected reduced stomatal conductance and biochemical limitations.
Observation Deciduous species generally showed greater smoke sensitivity than conifers.
Intervention effect Smoke did not significantly affect growth or secondary defense compound production.

Other claims from this paper (10)

Intervention effect Most listed apple cultivar-rootstock combinations produced larger trees at wider spacing.
Intervention effect Spacing did not affect tree size for Granny Smith and Jonathan on MM.102 or Delicious on MM.104.
Intervention effect Jonathan on MM.104 produced the largest trees at closer spacing.
Intervention effect Spacing did not affect apple yield per tree.
Observation Granny Smith gave the highest yield, followed by Delicious.
Observation Rootstock yield ranked NS, MM.106, MM.104, then MM.102.
Observation Widely spaced trees yielded about 80 t ha-1 between ages four and eight.
Observation Closely spaced trees yielded about 130 t ha-1 over the same period.
Observation Fruit quality was comparable to commercial fruit and showed no apparent density difference.
Recommendation High-density central-leader apple planting is judged superior in yield per hectare and productivity.
