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.
