Inflorescence — Lavandula angustifolia

Lavandula angustifolia Mill.

The inflorescence of Lavandula angustifolia is the key economically useful organ, where the bulk of the essential oil is localized. Its morphological parameters determine productivity, raw material quality, and the suitability of the crop for mechanized harvesting.

In the reference 41 varieties crop English lavender, where this is mentioned in the description.

The inflorescence of Lavandula angustifolia is a spike-like structure consisting of 6–10 false whorls located on the peduncle. During variety testing, morphological evaluation includes measuring the length of the inflorescence, which is typically determined from the level of the second lowest whorl, as well as counting the total number of flowering shoots on the bush. In standard forms, the inflorescence length varies from 4 to 15 cm, while the raw material yield of commercial varieties can reach 90 dt/ha or more.

The biological features of the inflorescence directly affect the economic efficiency of cultivation. The density of the whorls and the overall linear dimensions correlate with the essential oil yield, and selection for the uniformity of peduncles and their standard length of up to 10 cm ensures the feasibility of mechanized harvesting. To evaluate new varieties, the morphological characteristics of the inflorescences are recorded in accordance with international protocols to establish indicators of distinctness, uniformity, and stability.
