propagation of selected clematis l. cultivars by softwood cuttings

The goal of the experiments carried out was to compare the rooting ability of two types of softwood cuttings. Nodal softwood cuttings with two leaves were used and bud cuttings with one leaf. Clematis ´Madame Baron Veillard´ and Clematis tangutica ´Golden Tiara´ were chosen as model plants. Nodal softwood cuttings were 40 to 50 mm in length. Their base was wounded and stimulated by auxins.The leaf area was reduced. Bud softwood cuttings were created by a longitudal cut and dividing of 15 mm long nodal cutting. All the wound was stimulated by auxins. In addition the leaf area was reduced. The regeneration of the root system was managed under controlled conditions. Nodal softwood cuttings and bud softwood cuttings of Clematis ´Madame Baron Veillard´ and Clematis tangutica ´Golden Tiara´ rooted on average from 84% to 92%. Statistical evaluation showed fairly insignificant differences in the rooting ability of the tested types of cuttings.
