RHYSOGENESIS OF LAVANDULA ANGUSTIFOLIA AND PECULIARITIES OF ROOTED PLANT DEVELOPMENT
Lavandula angustifolia has a great economic importance in perfumery, cosmetics, food manufacturing, aromatherapy, and pharmaceutical industry. This species finds its phytosociological optimum in the sub-Mediterranean region. Latitudinal and altitudinal gradients are expected to affect species diversification in peripheral alpine populations. In this study, phenotypic traits including morphometric parameters, volatile organic compounds and essential oils were analyzed in lavender peripheral populations selected in order to explore different ecological conditions. Plants were cultivated under uniform conditions to observe variations due to the genetic adaptation to native environments and to exclude the short-term response to environmental factors.
According to the research, the peculiarities of the regenerative ability of Lavandula angustifolia lavender, which was propagated vegetatively by grafting, were established. Also, the influence of stimulating drugs for rooting, namely, treatment of cuttings with their solutions (Charcor, Heteroauxin, Emistim C, Epin-extra) was determined. The percentage of rooting cuttings of lavender narrow-leaved depending on the type of growth regulator. The influence of growth of regulating preparations for plants on specificity of formation of such morphometric indicators of rooted cuttings, as the linear sizes of an above-ground part, number and the linear sizes of the formed roots is carried out. These morphometric indicators are the basis for improving the efficiency of the vegetative method of propagation of lavender. This creates a prerequisite for the widespread use of ornamental plants, including lavender, for the needs of landscaping by simplifying the receipt of a sufficient amount of high quality planting material. After all, vegetative reproduction involves the preservation of all decorative features and properties of the mother plant. The issue of meeting the needs of the domestic market with the required amount of planting material of plants adapted to the soil and climatic conditions of the area remains extremely relevant. Improving the existing technological parameters of vegetative propagation of narrow-leaved lavender through the use of growth-regulating preparations for plants makes it possible to obtain high-quality and viable planting material. And this is a very important practical issue of ornamental nurseries, which requires careful study and analysis from a scientific point of view.
