Intervarietal specificity of the accumulation of trace elements by winter garlic in the Moscow region

Abstract

An assessment was made, and varietal differences in the levels of accumulation of five macro - and eight microelements of ten varieties of winter garlic were established. It was found that in addition to the high content of potassium, magnesium, calcium, phosphorus and sodium, garlic is also an active accumulator of zinc, iron and silicon, which is a good source of minerals for the human body. It is demonstrated that the Podnebesniy variety is able to accumulate relatively high concentrations of magnesium. Based on our research on 13 elements in ecosystems with normal anthropogenic and technical impact, it was established that the level of accumulation of elements in plants depends on the element and has varietal characteristics. Basically, the varieties are distinguished by the level of accumulation of 1-5 elements. There are Dubkovskiy and Strelets varieties with a low level of accumulation of ten and seven chemical elements, respectively, and the Odintsovo Yubileyniy variety with the maximum accumulation of valuable elements: potassium, calcium, phosphorus, iron, silicon, manganese, aluminum and boron. On average, the elements for winter garlic varieties were distributed as follows in descending order: K>Mg>Ca>P>Na>Fe>Si>Z n>Mn>B>Cu>Al>Ni. The identified varietal features of the Allium sativum L. species can be taken into account when selecting an assortment to improve the mineral composition of the human vegetable diet.
