Abstract

Microshoots and softwood stem cuttings of five clematis varieties (Clematis section Atragene) were rooted in different substrates (perlite, peat-perlite, and sand-perlite). Microshoots rooted better and quicker than stem cuttings, independent of the substrate. Root dry mass of microshoots was more than twice as high compared to root dry mass of stem cuttings. For microshoots, number of primary roots was highest in sand-perlite and pure perlite. The continued growth resulted, however, in the highest total root length, number of root tips and number of forks in peat-perlite. Microshoots obtained the largest average root diameter in pure perlite. There was no difference in root dry mass of microshoots among the substrates. For stem cuttings, rooting percentage and speed of rooting was higher in pure perlite (71%), and lower in peat-perlite (36%). The number of primary roots and root dry mass of stem cuttings was highest in sand-perlite and pure perlite. (C) 2002 Elsevier Science B.V All rights reserved
