Physiological Attributes of 11 Northwest Conifer Species

摘要

The Quantitative description & simulation of the fundamental processes thatcharacterize forest growth are increasing in importance in forestry research. Predicting future forest growth, however, is compounded by the various combinations of temperature, humidity, precipitation, & atmospheric carbon dioxide concentration that may occur. This report provides model parameters for 11 conifer species of the Inland Northwest. The relationship of wet leaf weight to dry leaf weight is also presented. The data in this report can be used to calibrate & constrain physiological parameters for modeling physiological processes of 11 conifer species in the Inland Northwest. Field measurements of A,A, max,g,g,max,c, predawn water potentials, analysis of leaf nitrogen concentration, carbon isotope discrimination (D), & values of c, & intrinsic water use efficiency (A/g) inferred from the carbon composition (Dl3C) are presented.
