    Productivity indices in Lavandula Angustifolia mill. Varieties, sixth year of vegetation [Articol]
    (Editura USM, 2025) Butnaraș, Violeta; Balmuș, Zinaida; Cotelea, Ludmila
    The evaluation of quantitative character indices – lant height and diameter, number of flowering stems per plant, inflorescence and floral spike length, number of whorls on the floral spike, raw material yield, and essential oil content – allowed for the characterization and assessment of each lavender variety-clone. The varieties under study synthesized and accumulated an essential oil content at standard humidity (60%) exceeding 2% (Svetlana – 2.199%; Alba 7 – 2.188%), and on dry matter basis exceeding 5% (Svetlana – 5.498%; Alba 7 – 5.472%). Raw material yield varied from 3.6 t/ha to 7.7 t/ha depending on the variety, with the most productive being Svetlana (7.7 t/ha), Alba 7 (7.3 t/ha), and Favoare (6.7 t/ha). The essential oil yield in the evaluated varieties-clones ranged from 11.6 kg/t to 22.0 kg/t. The highest yields were recorded in the varieties: Svetlana (22.0), Alba 7 (21.8), and Favoare (17.1) kg of essential oil per ton of fresh inflorescences.

    EVALUAREA SOIURILOR DE PLANTE MEDICINALE ȘI AROMATICE REZILIENTE LA FACTORII STRESOGENI AI MEDIULUI, BOLI ȘI DĂUNĂTORI
    (CEP USM, 2023) Balmuș, Zinaida; Cotelea, Ludmila; Butnaraș, Violeta; Goncearuc, Maria; Botnarenco, P.
    The varieties of Salvia sclarea provides a production of 15.4– 19.5t/ha of inflorescences and guarantees the yield of 54.5–73.5 kg/ha of essential oil. The essential oil content of Lavandula angustifolia varieties in the dry years is higher than in the years with normal atmospheric depositions. The productivity of the lavender varieties is higher (7,4 -7,7 t/ha) of inflorescences and 155,2- 179,2 kg/ha of essential oil. We can conclude that the varieties are part of different groups of maturity, high production of raw material, high content of essential oil. They are resistant to frost, winter and drought.
