Micronutrient composition of woody plants in Central Yakutia

Resumo

A study of micronutrient composition of twigs and needles of Dahurian larch (Larix dahurica Turcz. Ex. Trautv.), Scots pine (Pinus silvestris L.), and Siberian spruce (Picea obuvata Ledeb.) is carried out in Central Yakutia. Significant contents of phosphorus, calcium, magnesium, iron, iodine, selenium, and other macroand microelements; vitamins C, E, B₁ to B₆, and PP were found. However, the concentrations of them in the needles and branches were different. The content of heavy metals did not exceed the maximum permissible concentration (MPC) and was rather lower than that in the other regions of Russia.
