During all the dates of account of O-type, there were more fl owers than in the MS
component, which indicates no synchronicity of fl owering of mating components, and
which ultimately affects negatively the degree of tying seeds, its germination, and seed
production.
The minting of 50 percent of the plants of O-type somewhat reduced the intensity
of its fl ower formation during the whole period of fl owering, compared to the control
(Figure 18.2(b)). Thus, at the beginning of fl owering 124.5 fl owers/plants were formed
without minting and 98.4 with minting. Similar results were obtained in the last date
of accounting.

(а) without—control (b) under 50 percent of the plants of O-type (c) under 50 percent of plants
of O-type and 100 percent of plants of CMS component.
There is a significant increase in the intensity of flower formation in the early phase
of the stem formation and a slight decrease in the other two phases—154.0-748.2 pc./
plant in the plants of CMS component without their minting. That is, the minting of 50
percent of plants of O-type ensured the synchronous flowering of both components at
the beginning of flowering, and at its end.
