Vegetative propation of Lavandula dentata florescides in diferente physiological courses

Abstract

Aromatic, medicinal and spicy flowering plants, such as Lavandula dentata, usually present
long periods in the reproductive stage, making it difficult to use commercial matrices for vegetative
propagation. In view of this difficulty, the purpose of this work was to evaluate the percentage
of rooting and length of the largest root of flowered or non - lavender cuttings, submitted or
not to the basal cutting of the cuttings inside the water. This experiment was carried out in the
Nucleus of Agroecology Studies (NEA) of the University of Passo Fundo (UPF), in the middle
plateau region of Rio Grande do Sul, Brazil, in the spring of 2016. The experiment was a 2x2
bifatorial Type of cut) with a randomized block design, with six replicates, installed in styrofoam
trays using as substratum charcoal rice husk and conducted in greenhouse with nebulization.
After 50 days the percentage of rooting and length of the largest root were evaluated. It was
observed that the presence of the flower interfered in the rooting, not being statistically significant
in the length of the largest root, as well as the cut of the cutting within the water did not
alter the rooting.
