The genus Scutellaria L. (Lamiaceae family) includes about 350 species, occurring in Europe, the USA and East Asia. Scutellaria baicalensis Georgi (Chinese skullcap) is the most studied and widely used species of this genus. It is a valuable medicinal plant which has a long history of use in traditional as well as modern medicine. Its roots are used as the famous traditional Chinese medicine Huang-Qin, which is recorded in Chinese Pharmacopoeia, European Pharmacopoeia, and British Pharmacopoeia [10]. Scutellaria baicalensis is an herbaceous, perennial species with a short multi-headed rhizome that gradually passes into a thick, fleshy root positioned vertically. The stems are erect, 4-angular, branched and slightly pubescent. The leaves are opposite, lanceolate, with ciliated edge, acute tip, short-petiolate or sessile. The dark blue bi-labiate flowers located in the axils of the upper leaves are arranged along the stem. The seeds are black, nutlets, about 2 mm long and about 1-1,5 mm wide. Chinese skullcap (S. baicalensis) is one of the 50 fundamental herbs of the traditional Chinese medicine used since ancient times to treat inflammation, hypertension, bacterial and viral infections. It also improves the general condition of the body, the functional state of the cardiovascular system and central nervous system. Multiple scientific studies have shown that over 40 compounds have been isolated and identified from Scutellaria baicalensis, including flavonoids, terpenoids, volatile oils and polysaccharides [4, 11]. Flavonoids are the basic chemical constituents that induce the antiviral, anti-inflammatory, hepatoprotective, hypotensive, vasodilator, antioxidant, antimicrobial, antihistaminic and sedative effects [2, 3, 5, 7, 9, 12] of the plant. The anticancer effect of S. baicalensis extracts has been, also, scientifically confirmed [6]. Due to the active principles (baicalin, baicalein and wogonin), the roots of the plant are a promising remedy in the treatment of blood cancer [3] The research was conducted during 2017-2020. The experiments were done in the experimental field of the collection of medicinal plants of the “Al. Ciubotaru” National Botanical Garden (Institute). The plants were obtained, by the international exchange of seeds, from the Botanical Garden of Lodz, Poland, in 2006 [1]. Phenological observations [8] and biometric measurements were made during the growing seasons [13]. The germination coefficient of the seeds was determined in laboratory and greenhouse conditions. In laboratory conditions, in Petri dishes on filter paper moistened with distilled water (100 seeds in 3 repetitions); in greenhouse conditions by incorporating 100 seeds in a special substrate in 3 repetitions. Seed germination was assessed depending on the duration of their storage (1 year, 2 years and 3 years). Under greenhouse conditions, the experiments on the germination of seeds were carried out at the end of February, using a special substrate (chernozem, leaf soil, peat in a 2:1:1 ratio). The study on the characteristics of growth and the phenological stages of the cultivated plants was carried out according to the methodological guidelines commonly used at present [14, 15].
