Experiments with selected naturally occurring and synthetic plant growth regulators applied as a root soak to dormant southwestern ponderosa pine seedlings revealed that only gibberellins (GA3; and GA4/7) significantly increased height growth. The effects of gibberellins on root growth was variable. The regulator o-coumaric acid, significantly increased root ovendry weight. Application of hormones and regulators as a top dip was ineffective. Forest Sci. 28:156-160.
