Structural organization of shoot system of Gentiana L.

Two groups of shoot formation models in the genus Gentiana L. were highlighted. The models differ significantly in terms of shoots morpho-functional differentiation. In particular, the first group includes shoots systems with shoots which potentially complete their development with the generative organs formation and in any case form the part of the shoot system. The second group of shoot systems includes those with vegetative and generative shoots and only former are involved in the formation of perennial part of shoot system. The new models of shoot formation for description of the structure of shoot systems were proposed.
