Abstract:
The crop saving is no less important task for farmers than growing it. Crop losses reach 15 percent when sunflower seeds are
stored incorrectly. We have conducted an experiment to determine changes in the biochemical composition of sunflower seeds of
Lohos and Persei hybrids during long-term storage. We have used laboratory analytical and mathematical statistical methods of
research, according to generally accepted methods. The analyzed research on this problem by both national and foreign scientists
indicates the relevance of this issue. Our experiments have not revealed a significant difference in the biochemical composition of
different hybrids seeds during storage. Throughout the first 6 months of storage in the sunflower seeds post-harvest maturation
occurs. It is set that due to antioxidant components in the seed the peroxide processes are inhibited at the end of the first year of
storage. At the end of the second year of storage the content of free fatty acids in the sunflower seed of the investigated hybrids
increased and was higher than the initial values. According to the results of laboratory researches it has been proven, that the seed
material of sunflower does not have substantial changes in biochemical composition during two years under standard storage
conditions.
