Abstract

The influence of the environment on the studied characteristics can be determined when growing genetically similar plants in different environmental conditions. The medicinal plant Leonurus quinquelobatus Gilib. (five-bladed motherwort) belongs to a group of plants that are most responsive to changes of environmental conditions. Plants were grown from genetically uniform seeds in trial plots in three different southern regions of West Siberia (Kemerovo, Novosibirsk, and Kamlak Village, Altai Republic). Measurements were performed for 10 model live plants in each trial plot three times per growing season during three years. Variability of 23 vegetative and generative traits was studied based on linear, quantitative, and calculated data. The following traits correlated significantly with the phase of development: height of plant; branching of first-order shoots; length of the generative parts; inflorescence size share in plant height; width of generative part of the shoot; number of generative internodes of the first-order shoot; numbers of internodes with buds, flowers, and fruit; flowering index; fruiting index. The following traits changed significantly in different habitats: plant height; branching of first-order shoots; all generative traits studied. The branching and flowering indices changed due to the interaction of factors. The projection area of the aboveground part and the number of third-order shoots on a second-order shoot did not depend significantly on either the development phase or the growing region. For further research, the number of morphological traits under study could be reduced depending on the aims of the research
