From: Seasonal variations of auxin and gibberellin A4 levels in cambial-region tissues of three conifers (Pinus elliottii, Chamaecyparis obtusa, and Cryptomeria japonica) with inherently different wood densities

Relationships between seasonal ratio of IAA levels and wood density in three conifers. The seasonal ratio of the IAA levels is the ratio of the average value of the IAA levels during late season (July, September, and November) to that during early season (May and the following April)
