Waring, R. H.; Gholz, H. L.; Grier, C. C.; Plummer, M. L. 1977. Evaluating stem conducting tissue as an estimator of leaf area in four woody angiosperms. Canadian Journal of Botany. 55(11): 1474-1477.
Four woody angiosperm species representing an evergreen tree (Castanopsis chrysophylla(Dougl.) A.DC.), a deciduous tree (Ater macrophyllum Pursh), an evergreen shrub (Rhododen-dron macrophyllum G.Don), and a deciduous shrub (Acer circinatum Pursh) were sampled toassess the relation of cross-sectional area of conducting tissue in the stem to leaf area. For the firstthree species listed, a linear relation between conducting area and leaf area was obtained with r2values ranging from 0.89 to 0.96. For Auer circinatum the relation only approached linearity witha log transformation of both axes with r2 = 0.80.
