Abstract. Scutellaria baicalensis Georgi is a valuable medicinal plant. Distributed in Transbaikalia, Amur, in the Far East. Natural reserves of the skullcap of the Baikal sharply reduce, to preserve natural populations, the plant must be introduced into the culture. The main method of reproduction of the skullcap is seed. Therefore, the issue of increasing the germination of seeds and the possibility of a seedling method of reproduction are relevant. Study was conducted in 2017–2018. The scheme includes four options: 1) control (seeds soaked in distilled water); 2) Humate + 7 (12 hours exposition); 3) Humate + 7 (24 hours exposition); 4) Humate + 7 (48 hours exposition). The concentration of Humat + 7 solution in all variants is 0.1 g / 100 ml. In the process of the study, it was established that the maximum germination energy (82.3 %) and laboratory germination (89.7 %) capacity of the Baikal skullcap are characteristic for the fourth variant. The highest morphometric parameters of plants: height, number of pairs of leaves, length and width of leaf blades, biomass structure – were also obtained in fourth variant. Similar results were noted in the third variant.
Keywords: Baikal skullcap, seed treatment, Humat + 7 trace element, exposition, germination energy, laboratory germination.
