THE EFFECT OF GROWTH REGULATORS ON ROOTING OF ERICACEAE PLANTS |
| Author: | K. Górecka |
| Abstract:
Experiments were carried out concerning the effect of growth regulators on the rooting of Rhododendron simsii, Leucothoe fontanesiana, Vaccinium vitis-idaea, Calluna vulgaris, Erica tetralix, Arctostaphylos uva-ursi and Rhododendron catawbiense cuttings. Application of growth regulators usually enhanced the rooting processes. The 100 ppm of IBA solution /24 hr treatment/ was generally better than IAA, at the same concentration. The concentrated talcum preparations of IBA and its concentrated solutions /1.0 – 5.0 g per liter/ caused beneficial responses in rooting of cuttings. Boron /as boric acid/ and its mixture with IBA or IAA improved the rooting of V. vitis-idae and A. uva-ursi cuttings. | |
