Аннотация:[Structure of the stomatal complexes of vegetative organs in some Amaranthus L. species]
It is shown that there are quantitative structural distinctions between the different types of the stomatal complexes on the vegetative organs of 11 investigated Amaranthus species, so different stomatal complexes are proposed to be considered as the variants of the same stomatal complex type. The opinion of the expediency to consider the perigenous and mesoperigenous stomatal complex types as the same type is supported. It is stressed the necessity to take into account along with peculiarities of the leaf stomatal complex structure also peculiarities of the stem stomatal structure.
