Root Regeneration and Field Performance of Hormone-Treated Red Oak Seedlings
Northern red oak often grows slowly the first few years after out-planting, and weed control may be required for an extended time. In an attempt to stimulate early growth, hormone mixtures of indole-3-acetic acid (IAA) and kinetin were applied to seedlings before planting by soaking roots in hormone solutions, by application of vacuum during the root-soak period to increase hormone penetration, and by dipping roots in starch polyacrylate gel with hormones. Root regeneration potential and field performance were markedly improved when hormone-treated trees were planted on a weed-free site. A safe and beneficial hormone mixture for soaking seedling roots is 200 mg/l IAA plus 0.1 mg/l kinetin. North. J. Appl. For. 5:25-28, March 1988.
