From page 127...
... INTRODUCTION ratio of Other various a tree's The allocation of carbon into various components of trees and ecosystems changes depending on the environment (Waring 1983~. Trees on an exposed headland exhibit extreme stem taper and an extensive supporting root system.
From page 128...
... Sometimes the historical development of tree crowns can be reconstructed by knowledge of what age sapwood converts to heartwood and from branch scars when limbs die (Margolis et al.
From page 129...
... PHLOEM/SAPWOOD AREA If the transport of photosynthate through phloem is inhibited, then the cross-sectional area of sieve cells should be reduced in relation to leaf area or the surrogate, sapwood cross-sectional area. Scots pine trees provided with optimum water and nutrients exhibit a ratio of phloem/sapwood area in the stem, half that of unfertilized and unirrigated trees (Dr.
From page 130...
... BARK BEETLE ATTACKS/ GROWTH EFFICIENCY In many forests, bark beetle attacks follows a reduction in tree vigor. Christiansen et al.
From page 131...
... Growth efficiency provides an index to the density of bark beetle attack required to kill lodgepole pine trees. Filled or partly filled circles represent the proportion of conducting tissue killed on attacked trees.
