Lengthwise shoot symmetry and its features in plants of Lamiaceae family of Ukrainian flora

Abstract

Yosyp Berko

The features of lengthwise symmetry of monocarpic shoots (on example of changing of the length of internodes in its elementar metamers) in more than 60 species of half-shrub and grass plants from the family Lamiaceae were studied. The statistically representative plots of changes of this parameter for the most species appeared to be one-vertex, but very different by shape and specific. Two- and multi-vertex plots characterize limited number of species and appear as a result of quantized growth of shoots.
