THE QUALITY OF SUGAR BEET SEEDS AND THE WAYS OF ITS INCREASE - Ecological Consequences of Increasing Crop Productivity - page 178

To stimulate the seed under the production conditions, 12 parties of calibrated seed
of diploid hybrids Ukrains'kyi СhS 72, Vesto and triploid Dobroslava, Oleksandriia
were used. The stimulation of seed was performed by the method of Institute of Bio-
energy Crops and Sugar Beets. Nonstimulated seed was sown in the control variant.
We determined in the laboratory conditions germination energy, fi eld germination,
and seeds purity [8], the mass of 1,000 fruits and one sprouting and one seeding [9].
The selection of the average seed samples was performed in accordance with applica-
ble State standards of Ukraine ( DSTU) [10]. The number of fl owers by the experiment
variants was determined by calculation; the seeds yield was determined by weighing
the heap from the calculation plot and from the individual seed plants in the fi eld
conditions on the seed plants. The statistical processing of the experimental data was
carried out by the methods of R.A. Fisher [11] with the appropriate computer software.
18.3 RESULTS AND DISCUSSIONS
The research has proved that the minting of seed plant-mating components has a posi-
tive effect on the processes of growth and development and on the flowering syn-
chronicity and flower formation in particular. The suspension of the stem tops growth
results in redistribution of nutrients, improves the supply of flowers formed, which
contributes to additional formation of high-quality seeds and thus an increase in its
productivity.
The experiments are conducted with the plants of CMS component and Umans'kyi
ChS 97 triploid hybrid O-type in tunnel isolation (Figure 18.1).

the depths of picture and without it in the foreground).
Minting is free (control) in the variant; the variability of the number of fl owers,
during the fl owering, by the date of accounting was in the CMS component from 58.5
to 806.7 pc./plant in the sterility fi xator (O-type) from 124.5 to 939.9 pc./plant (Figure
18.2(a)).
