Multiplication of lavender (<i>L. angustifolia</i>) and lavandin (<i>Lavandula x intermedia</i>) in explant culture

Abstract Lavender plants are preferably propagated vegetatively. The aim of the work was to propose composition nutrient media for in vitro multiplication Lavandula angustifolia (var. Krajová and Beta) x intermedia Budrovka Grosso). Explant cultures were initiated from apical or nodal segments. Apical segments more suitable regenerated highest number shoots MS medium supplemented with 1 mg/L BAP without 0.1 IAA all used varieties. Nodal var. Budrovka, where not statistically different between among tested. Shoot L. varieties most effective 0.5 BAP. For variety Grosso, optimal BAP, while a similar IAA. All genotypes rooted frequency on growth regulator-free half dose salts. After transplanting into soil ex acclimatization, plantlets survivability after 10 weeks 78.9 – 87.7%, except Beta lower 50%. proposed procedures enable rapid plant Grosso Krajová. With variety, it is advisable continue working optimization verify whether can be further optimized.
