Table 1 Initial tree densities and growth traits of sample trees

From: Seasonal variations of tracheid formation and amount of auxin (IAA) and gibberellin A4 (GA4) in cambial-region tissues of mature sugi (Cryptomeria japonica) cultivar grown in a Nelder plot with different tree densities

  1. The values represent averages in three trees; values in parentheses indicate standard deviations. Different characters show significant differences among density-zoning symbols (p < 0.05)
  2. Symbol tree-density-zoning symbol, Density initial tree density, n number of sample trees, H tree height, DBH diameter at breast height, HCB height at crown base, H/D ratio height-to-diameter ratio
