Effective methods of preparing lavandin (Lavandula hybrida Rev.) cuttings for establishment of industrial plantations in southern Ukraine
Abstract
Objective: The purpose of the conducted experiment was to determine the effect of growth regulators and organic fertilizers on the rhizogenesis of lavandin cuttings (Lavandula hybrida Rev.).
Material and Methods: Research was conducted from 2020 to 2022 in the nursery of essential oil crops of the plant breeding department of the Institute of Rice of the National Academy of Agricultural Sciences. Lavandin maternal plants were used to prepare the cuttings. Before planting, the cuttings were treated with solutions of growth regulator and organic fertilizer.
Results: The percentage of rooted cuttings depended on the weather conditions and the method of their preparation before planting. Treatment of cuttings with a solution of a growth regulator and its mixture with an organic fertilizer significantly increased this indicator, had a positive effect on the dynamics of the accumulation of vegetative mas and allowed obtaining a larger number of seedlings of the first class.
Conclusion: Preparation of lavandin cuttings should be performed in early spring from semi-lignified shoots of the fifth and sixth orders of young, five-year-old maternal plants. For better rooting of cuttings, mixtures containing auxins (indolyl-3-butyric acid) and organic fertilizers with live cultures of soil microorganisms and nutrients in a form readily available to plants should be used.
