| Summary: | Individuals of Dracocephalum nutans L. have been studied at different altitude levels from 460 to 2437 m above the level seas. The influence of the height gradient on morphological characters has been shown: the number of generative and vegetative shoots, the height of the generative shoot, the length and width of the leaf blade, length of its petiole, and inflorescence length. It was found that the height gradient has the greatest influence on the height of the generative shoot and the length of the inflorescence. When individuals grow higher along the altitude gradient, the height of the generative shoot and the length of the inflorescence decrease. The fluctuation of the average values of the traits of D. nutans in a wide range was established. The intrapopulation analysis of D. nutans individuals does not depend on the height factor. |
