In the study, method of atomic emission and mass spectrometry with inductively coupled argon plasma was used to determine average concentrations macronutrients (Ca, K, Mg, Na, P), essential trace elements (Cu, Fe, I, Mn, Se, Zn) conditionally (B, Co, Cr, V, Si, Li, Ni), as well toxic metals (Al, As, Cd, Hg, Pb, Sr, Sn) in wild berries most often included diets Magadan region residents: Blue hon...

В статье представлены результаты мониторинга состояния зеленых насаждений городского парка им. Мичурина города Сыктывкара. результате проведенных работ установлено, что зеленые насаждения в границах исследуемой территории четырнадцатью видами, из них доминирующими являются: Betula pendula Roth, Sorbus aucuparia L. Состояние древесно-кустарниковых растений оценивается как хорошее. На всей наблюд...

Aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. This species has been endangered at northern forests of Iran; therefore micropropagation of adult trees by bud culture may help to reforestation. The best sterilizing treatment was the buds washing with HgCl2% 0.1 solution for 7 ...

Larvae and imagos of bees rely exclusively on floral rewards as a food source but host-plant range can vary greatly among bee species. While oligolectic species forage on pollen from a single family of host plants, polylectic bees, such as bumblebees, collect pollen from many families of plants. These polylectic species contend with interspecific variability in essential nutrients of their host...

Seasonal variation in the antioxidant activity and content of phenolic compounds was studied for the 70% methanol extracts of Sorbus aucuparia leaves harvested monthly over the full course of the growing season. The antioxidant potential of the extracts was evaluated using two complementary in vitro tests: the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging assay and the AAPH [2,2'-azob...

BACKGROUND AND AIMS The low-temperature range limit of tree species may be determined by their ability to produce and disperse viable seeds. Biological processes such as flowering, pollen transfer, pollen tube growth, fertilization, embryogenesis and seed maturation are expected to be affected by cold temperatures. The aim of this study was to assess the quality of seeds of nine broad-leaved tr...
