Abstract:
A study conducted in 2000 determined the effects of non-amended rooting medium, dolomitic-limestone-amended medium, and IBA and NAA concentrations on root initiation and root growth of Clematis socialis. Clematis socialis is an endangered native clematis, with small populations known to exist in two Alabama counties and one Georgia county. Propagation of the species would introduce new genetic material for hybridization and provide plants for additional self-sustaining populations in protected areas. Cuttings propagated in non-amended media were most successful in a sand or perlite medium, which produced a significantly greater root number and root quality than those propagated in vermiculite or sphagnum peat, pine bark, and sand medium. Root length, number, and root quality increased with increasing rate of dolomitic limestone incorporated into a sphagnum peat, pine bark, and perlite medium. Root length, number, root quality, and cutting survival increased with increasing rate of IBA and NAA up to 5000 ppm IBA and 2500 ppm NAA.
