Additional file 2 of Half-leaf width symmetric distribution reveals buffering strategy of Cunninghamia lanceolata

Additional file 2: Table S1. Regression coefficients, R2, horizontal and longitudinal distance of apex, and the ratio between the horizontal distances of apex with total length of main relationships used to estimate the length and half-leaf width trajectories in the selected leaves. The best fitting on leaf length(X) and half-leaf width(Y) is obtained by quadratic-function models: Y=C + B1X + B2X2, and all regressions have p < 0.0001.
