Studiul microscopic al trihomilor glandulari și nonglandulari la genotipuri de Lavandula Angustifolia Mill. ssp. Angustifolia

Abstract

The microscopic and citochemistry study denotes 3 types of glandular trichomes (peltate, capitates type I and type II), implicated in the synthesis of the metabolites, including volatile oils (with biological and protective role) and one type of non-glandular trichomes with the potential adaptive role to stressors in 7 new genotypes (4 cultivars – Moldoveanca 4, Vis Magic 10, Alba 7, Aroma Unica and 3 hybrids – Fr.5S8-24, Fr.8-5-15V and Cr.13S-6-7) of sp. Lavandula angustifolia Mill., spp. angustifolia. The degree of development and distribution mode of both types of trichomes (glandular and non-glandular) varies according organs (stem, leaf, bract, flower calyx and corolla) and genotype.
