DescriptionBiweekly applications of 400 µg GA4/7 plus 25 µg NAA per bud from June 1 to August 10 promoted male and female flowering in longleaf pine (Pinus palustris Mill.), especially when combined with partial branch girdling and NH4N03 fertilization. Fertilization was the most effective single factor, and girdling was second. Cultivation had no significant effect on flowering. Vegetative bud growth was doubled by GA-NAA, independent of fertilizer stimulation.
