 note = {All the 114 branches of a 26-year-old hinoki (Chamaecyparis obtusa (Sieb. et Zucc.) Endl.) tree were cut along the stem. The following measurements were obtained on each branch : total length, clear length (length to the first fork of the second-order branches ),<br/>diameter at the base, diameter at the upper end of the clear length, and diameter at a distance of 10% of the total length from the base. The regression of branch dry weight, leaf dry weight or leaf area on diameter or diameter squared times length was examined on logarithmic coordinates. It was concluded that the diameter at the base d_0 was the most appropriate dimension for estimating the weight of a branch w_c, and the weight w_f and the area u of leaves on the branch, though the use of d_0 led to lessening accuracy of their estimates some extent, especially in leaves. Regression equations showing the allometric relationships of w_c [g], w_f [g], and u [d㎡] to d_0 [cm] were as follows : w_c = 10.8d_0^3.67 (r^2 = 0.93), w_f = 33.6d_0^2.46 (r^2 = 0.85), and u = 17.6d_0^2.47 (r^2 = 0.86).26年生のヒノキ個体に付着する114本の枝全部を層別に幹から切取り、各枝の全長、２次枝の付け根までの長さ、元口の直径、２次枝の付け根の直径および全長の1/10での直径を測定した。直径または直径の自乗に長さを乗じた値と枝重、葉重または葉面積との相対成長関係をそれぞれ調べた。枝重と元口径との間には、枝が採取された層毎に分離することのない相対成長関係が認められた。葉重および葉面積と元口径との間の相対成長関係は層間で分離する傾向であったが、元口径の測定の容易さから、元口径から枝重、葉重および葉面積を推定することが妥当であろうと判断された。元口径をd_0[cm],枝重をw_c[g],葉重をw_f[g],葉面積をu[d㎡]とすると、相対成長式はそれぞれw_c = 10.8d_0^3.67 (r^2 = 0.93), w_f = 33.6 d_0^2.46 (r^2 = 0.85), u = 17.6d_0^2.47 (r^2 = 0.86)であった。, 農林水産研究情報センターで作成したPDFファイルを使用している。},
