Abstract
The features of the elemental composition of seeds (stems) of beet (Beta vulgaris L. var. conditiva Alef.) of three varieties of selection of ARRIVG – branch of FSBSI FSCVG. The largest share of mineral elements is potassium (more than 1% of dry matter), as well as calcium, sodium, magnesium, and phosphorus (more than 0.4-0.5% each element). The seeds of the Karina variety accumulate the maximum amount of potassium, calcium, chlorine, and sulfur. According to the content of sodium and phosphorus in the seeds, a variety of Zhukovchanka, magnesium and iron – Demetra is distinguished. Of the microelements, zinc and manganese predominate. A significant variability in the accumulation of elements by seeds of different beet varieties is shown. Significant varietal differences were observed in the accumulation of titanium, aluminum (variability of more than 70%), silicon, manganese, nickel, rubidium (more than 60%). The accumulation of sulfur, chromium, lead, zirconium, and zinc is more stable in varieties. It is noted that when seeds germinate in the seed skin, the content of sodium and chlorine increases sharply (by 3.4-7 times) in comparison with the original seeds.
