Content of essential elements in fig fruits of foreign selection cultivars

Abstract

Objective. Fruits of figs from the collection of the Nikitsky Botanical Gardens: Figue Grise, Randino and Fig Blanche were studied for use as raw material for health products. Methods. The content of elements was determined using AAS “Kvant 2MT” in the emission mode (K) and in the absorption mode (Ca, Mg, Fe, Mn, Cu, Zn). Results. The content of seven essential elements in the fruits of two generations (yields) was studied for the first time. It was revealed that the fruits of the studied fig cultivars contain high quantities of potassium, calcium and magnesium, and satisfactory quantity of ferrum. In the first generation of fruits, the ferrum content is higher by 72-73%, potassium by 4.5-18.4%, than in the second generation of fruits. The fruits of the second generation accumulate more calcium (by 28-31%), magnesium (by 11.6-26.8%), zinc (by 9.9-23.3%) and manganese (by 5.2-17.7 %). Conclusion. The cultivar of early maturity Fig Blanche, in which the fruits of two generations are characterized by the maximum of three cultivars of potassium (15970 mg / kg in the I-st generation, 13020 mg / kg - in the II-nd generation), magnesium (2520 mg / kg and 2810 mg / kg), ferrum (15.54 mg / kg and 9.05 mg / kg), zinc (1.51 mg / kg and 1.69 mg / kg), cuprum (2.24 mg / kg and 1.93 mg / kg) and manganese (2.38 mg / kg and 2.51 mg / kg) content.
