Assessment of propagation efficiency of Clematis L. green cuttings in Western Siberia

Abstract

In recent years, clematis have become very popular in landscaping around the world. The representatives of this species are characterized by long-term decorativeness, a fast growth rate and a variety of forms. To meet the needs of urban landscaping, a large amount of planting material adapted to local conditions is required. In this regard, it becomes necessary to study individual parameters of their reproduction, taking into account the capabilities of producers of planting material in the region. The varieties that are well adapted to local climatic conditions, are stable decorative were selected as the objects of research. These are representatives of the Jacqueman groups (Rhapsody, Hagley Hybrid, Jerzy Popieluszko and Madame Baron Veillard) and Viticella (Purpurea Plena Elegans, Polish spirit, Ville de lyon). The varieties Ville de lyon (93%), Madame Baron Veillard (82%), Purpurea Plena Elegans (80%) have the highest root-forming ability. The propagation of cuttings is influenced by many factors such as the phenological phase of development during the harvesting of cuttings, the microclimate parameters in the artificial fog greenhouse and the varietal characteristics of the culture. In the future, it is necessary to work out the issues of deplantation of annual plants into containers for overwintering in protected ground.
