Gibberellin affects rooting of hybrid poplar clone NE-277

Gibberellic acid, when applied at optimum concentrations, appears promising for improving root development on hardwood cuttings of known parentage, as shown in the following exploratory investigation, with increased demand for quality hardwoods by the wood-using industries, the need for hardwood planting stock will also increase; consequently, nurserymen and forest landowners may reasonably make a greater use of vegetative cuttings in their reforestation programs. It is apparent that more precise information on the feasibility of using growth-promoting substances is needed, particularly w ill regard to concentration and application method when applied to cuttings, seed, or seedlings.
