Abstract
The variability in the development of Scutellaria baicalensis Georgi (Lamiaceae) plants collected from natural habitats (Zabaykalsky krai, Amur oblast, and Primorye) and grown under the same culturing conditions (Novosibirsk) is analyzed. It has been found that interpopulation differences in morphological characteristics of S. baicalensis and the timing of the onset of phenophases developed in nature are preserved under new growing conditions. Data analysis shows the existence of significant differences (t > 3) between the steppe Zabaykalsky and forest Primorye coenopolations (CPs) in plant height, number of pairs of leaves, and number of shoots, both in nature and during introduction. The flowering period in the Zabaykalsky CPs comes earlier than in the Primorye CP, both in nature and in culture. Individuals of Zabaykalsky CPs bloom in early July in culture. The flowering period in the Primorye CP begins at the end of July-August; the seed ripening period is extended, especially in the first years of introduction. It is possible to allow the formation of steppe Zabaykalsky and forest Primorye ecotypes.
