ABSTRACT: For the first time, a comparative analysis of the
structure of the apical meristem and the node of the main shoot of two forms of
the indeterminate kind Namangan-77 and the determinant line of Determinant-2
and Determinant-3 of G. hirsutum in
the kidney ding phase was carried out. In the apical meristem of the
indeterminate form Namangan-77 is characterized by the recessive homozygous
state of the mutant gene (inlinl) and the dominant
homozygous, heterozygous state of the fruiting branch gene S-s: inlinlSS,
inlinlSs, inlinlss—more pronounced vegetative, vegetative, with
this, this form is predominated by the
continuation of first-order shoots and the monopodial branching type with unlimited
apical growth, accompanied by a uniform elongation of the internodes. In the
apical meristem, in the forms of the determinant lines, Determinant-2 and
Determinant-3 are characterized by the dominant homozygous state of the mutant
gene (InlInl) and the recessive homozygous state of the
allelic gene (ss)—InlInlss—there is a generative collateral kidney in
the axillary leaf axial sinus, which is why these forms of the vegetative apex
of the shoot when they transit to the reproductive state turn into a floral
apical meristem and a sympodial branching type what happens through the
development of inflorescences. Obviously, this is a consequence of a change in the
phytohormonal status in the apical part of the stem as a result of the
interaction of the mutant gene Inl and gene S. The node of the main
stem in all forms was also studied, and a three-beam-three-lacuna type of
structure was revealed, which is a fairly persistent characterizing feature of
large taxa and can be used in their taxonomy.
