Fig. 1

Seasonal variation of xylem formation in sugi trees grown with different tree densities. Different characters show significant difference among density-zoning symbols (p < 0.05). Error bars indicate the standard deviations. Cell wall ratio of initiation of xylem formation—June was obtained from the xylem formed near pin marking in June. A Number of tracheids, B cell wall ratio
