Abstract

The plants containing essential oils are widely used in many industries and medicine. In this regard, it is necessary to conduct research on the introduction of essential oil crops with high productivity and yield to create a strong raw material base. The purpose of the study was to assess the morphological characteristics, seed productivity and quantitative content of essential oil in spike lavender under cultural conditions. The studies were carried out during the period of mass flowering of plants. It has been established that spiked lavender is winter-hardy and drought-resistant under cultural conditions, forms a bush 60 cm high, inflorescence yield is 1.22-3.1 kg/m2, actual seed productivity is 110-1500%, potential seed productivity is 216-2890. Seed productivity coefficient is 0.5-0.53%, laboratory seed germination reaches 90%, seed germination energy is 0.7%. The largest amount of essential oil in lavender was found in the mass flowering phase. During the budding period, the oil content increases, and towards the end of flowering and the beginning of seed ripening, the essential oil content decreases.
