The increase in seed yield is caused by the increase of 1,000 seeds mass and
decreases the seed in diameter less than 3.50 mm. Under the minting, we ob-
served a higher yield of seed and sown fractions 3.50-4.50; 4.50-5.50 mm,
especially under the minting of both components—50 percent of the plants of
O-type and 100 percent of plants of CMS component.
-
To regulate the process of plant growth and development, the components of
the crossbreeding is advisable to perform the minting of 50 percent of fixative
plant and 100 percent of plants of CMS component, which provides the largest
synchronicity of flower formation and flowering of hybrid components and
the productivity of seed plants.

It is found that in the process of uncalibrated seed polishing, the removing of
24.7 percent of mass pericarp has provided significant increase in the inten-
sity of seed germination. In 48 h after sowing, the number of seeds sprouted
increased by 32 percent compared with the control, where the seeds are not
polished.
-
It is proved that the pelleting shell together with protective agents create a
mechanical barrier to seed germination especially in the early stages—in 48 h
after sowing. Under these conditions, the stimulation of seed before pelleting
effects is positive on the intensity of the pelleted seed germination. In all the
variants with the stimulation, except the variant where the stimulation was
performed within 2 h with the moisture content of the seed 35 percent, the
number of germinated seeds of both hybrids was higher than in the control.
-
The optimum time of stimulation of the initial phases passage of germination
of hybrid Oleksandriia under which the number of sprouted encrusted tablets
in 48 h after sowing was 22 percent higher and the germination energy and
seed germination, respectively—by 7 and 6 percent higher than in the control
was the fourth regime of stimulation.
-
After the stimulated calibrated pelleting seed, the germination energy and ger-
mination of both the biological forms of beet was equal to those before pellet-
ing, but significantly higher compared with the control.
