Fig. 3 — a, b Surface and cross-section of the calyx of a blossom floret. These images were captured by CT. The glandular trichomes (GTs) of lavender are colored purple. c Top view and side view of a single GT separated from a flower at blossom. The GTs are composed of eight secretory cells and one secretory cavity. d–i Scanning electron microscopy images. The GTs of the flower (LAF), leaf (LAL), and stem (LAS) are colored purple, and non-GTs are in yellow. Scale bars = 1 mm (a, b); 50 μm (c–e, g, i); and 100 μm (f, h). j, k The relative and absolute contents of volatile terpenoids in LAF, LAL, and LAS. l The ecological function of the main volatiles emitted by opening flowers, flower buds, leaves, and stems. A large proportion of linalool, linalyl acetate, and lavandulyl acetate in opening flowers function as attractants for pollinators. At the flower bud stage, α-pinene, β-pinene, and β-ocimene, etc. provide defense against herbivores and predators. Borneol, camphor, 1,8-cineole, camphene, and bornyl acetate are the main compounds in leaves and stems and are always repellents to pests.
