The effect of auxinoid application on the planting stock root system
2005
A. Bártová | O. Mauer
The goal of the study was to verify the effect of growth substances from the group of auxinoids on the root system of European beech and Scots pine planting stock. The effect of growth substance application date (spring, summer dipping), the type of growth substance used (IBA, NAA), and the exposition to the growth substance (1, 2, 5 hours) were studied. The tests showed that the application of NAA and IBA did not stimulate the root system growth in Scots pine at any exposition of root systems to the growth substances. European beech exhibited a favourable effect of the 5-hour IBA exposition in the spring dipping. The summer dipping of European beech did not show a complex beneficial effect on the root system development at any of the expositions.
