- Аннотация: A structural and rhythmological analysis of shoot systems of three Atraphaxisspecies has been carried out. The species demonstrate differences in the structure of terminal synflorescences, floral units, andgenerative shoots. The duration of spring–summer flowering of Atraphaxisis determined by the number andbranching order of paracladia in synflorescence and by the length of generative shoots. The species differ inthe morphological differentiation of the axes and in the distribution of functions between generative and vegetative shoots. The main skeletal axes of A. frutescensare based on the generative shoots, which perform bothassimilative and reproductive functions. The species takes the life form of an aeroxylic shrub, dwarf shrub orsemi-shrub, depending on the preserved part of vegetative zone of generative shoots, which is determined bywintering conditions. The main skeletal axes of A. replicataare based on both generative and vegetative shoots.Terminal abbreviation, that is, the underdevelopment of terminal synflorescence in powerful generativeshoots, creates conditions for the transfer of reproductive function to small, early flowering generative shoots,which allows the species to adapt to a semiarid climate. The formation of a perennial axial system in A. pyrifoliais based on powerful branched vegetative shoots, making it possible to more fully implement the advantages of acrotonic branching and achieve a significant size. The specialization of generative shoots in the performance of the reproductive function in this species is most fully implemented.
