Winter water relations of a deciduous timberline conifer, Larix lyallii Parl.

  title={Winter water relations of a deciduous timberline conifer, Larix lyallii Parl.},
  author={James H Richards and L. C. Bliss},
The degree of winter desiccation resistance exhibited by Larix lyallii Parl. was assessed by determination of water potential components and content of buds, xylem pressure potential (Ψ xylem) of twigs and amount of damage through winter at timberline in the Rocky Mountains of Canada. Comparative measurements were made on sympatric evergreen tree species to evaluate differences in winter desiccation avoidance and tolerance between evergreen and deciduous trees. Total (Ψ) and osmotic plus matric… CONTINUE READING
