Abstract

Vegetative propagation techniques for some broadleaved tree species.

Abstract

Research was carried out initially with six tree species (Quercus petraea, Q. robur, Q. ithaburensis, Q. cerris Fraxinus oxycarpa [F. angustifolia subsp. oxycarpa], Tilia tomentosa) to determine the appropriate concentration of IBA for propagation. An IBA concentration of 0.5% gave maximum rooting of most species and was used in the propagation of softwood cuttings of eight broadleaved species (Robinia pseudoacacia, Elaeagnus angustifolia, Acer negundo, F. angustifolia subsp. oxycarpa, T. tomentosa, Platanus orientalis, Q. robur, and Liquidambar orientalis) in three rooting media (sand, gravel and sand + perlite). Significant relationships were demonstrated between rooting percentage and tree species, auxin level, the interactions of tree species with rooting media and tree species with auxin level.
