Table 3 Coefficients of correlations between amount of phytohormones and indexes of xylem formation

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

  Amount of IAA Amount of GA4
June August October June August October
Cell wall ratio −0.15 0.26 0.60* −0.11 −0.10 0.01
Cell wall thickness 0.27 0.41 0.54 −0.25 −0.17 0.30
R diameter 0.27 0.04 −0.24 −0.23 0.09 0.43
T diameter 0.53 0.20 −0.09 −0.40 0.06 -0.27
  1. Indexes of xylem formation in June, August, October, and December were the values measured on xylems formed at initiation of xylem formation—June, June–August, August–October, and October–December, respectively
