Abstract

The paper presents issues of optimizing the technology of growing popular terry varieties of clematis (Clematis L.) in Russia. Trimming groups, bookmark features of flower buds are described. The issues of reproduction and agricultural technology when laying uterine plantations are considered. A comparative analysis of traditional breeding technology with innovative technology (in vitro). The optimal nutrient medium for the stages of micro propagation, cultivation and rooting, enriched with vitamins and other substances. In experiments on green cuttings, 8 terry varieties were used. Estimated rooting of green cuttings by standard propagation technology. Spring cuttings are recommended for the varieties Bellof Woking (83%), Empress (81%), Blue Light (79%) and give a high yield of planting material from one mother plant. Two varieties with low rooting were selected—Purpurea Plena Elegans, Multi Blue. In vitro breeding technology has been developed for them. Accounting and observation of the development of two terry clematis varieties in the tissue culture: Purpurea Plena Elegans, Multi Blue. The aim of our study is to develop a technology for clonally propagation for these varieties, as well as the adaptation of micro plants of these varieties to non-sterile conditions. Therefore, in vitro propagation is recommended for these two varieties. An optimal substrate composition has been developed for the adaptation of clematis plants propagated in vitro, as well as for cuttings. The article provides recommendations for planting, pruning and caring for uterine plantings of clematis with double flowers in sheltered ground.
