Spicer, Rachel

Abstract:

Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To...

Wood density patterns of young Costa Rican trees in planted and natural forests

Creator:

Baker, David C.

Abstract:

In plantation forestry, rapid growth rate is favorable for wood production, but may decrease wood density, which is an important indicator of wood quality for both pulp and solid wood products. I looked for (1) differences in radial patterns of wood density between planted and naturally grown Costa Rican tree...
