“…Однако в случае наибольшей исследуемой в опыте концентрации марганца (90 мг/л) наблюдали снижение значений ОМС у всех исследованных сортов, за исключением сорта Форвард. Полученные результаты хорошо согласуются с данными Н. М. Казниной с соавт., согласно которым с повышением концентрации тяжелых металлов в субстрате для выращивания растений происходит уменьшение значений показателя ОМС [14]. Например, внесение избыточной концентрации марганца в среду выращивания способствовало снижению значений соотношения корень/побег у риса, причем у чувствительного сорта в большей степени, чем у толерантного [15].…”

Manganese belongs to the group of heavy metals, which at high concentrations can have a negative effect on plant development. Typical soils of the Kirov region are acid podzolic and sod-podzolic soils, which are characterized by high content of manganese compounds available for plants. Studied was the effect of manganese(II) ions at the concentrations of 30.0, 60.0 and 90.0 mg/l on the growth and antioxidant activity (AOA) of the superoxide dismutase enzyme (SOD) in the organs of 7 and 14-day-old barley plants grown in aquatic culture. Varieties and forms of barley 346-09, 29-11, Farmer 198-12, Forward and Bionik, resistant to acidic soils (Al3 +, H+) served as objects for the research; Belgorodskij 100 variety was used as standard. When manganese was added to the solution for growing, a decrease in root length and an increase in AOA of SOD in plant roots were noted. It was concluded that increased concentrations of manganese had an effect on the morphometric parameters and on AOA SOD of barley seedlings. It has been established that increasing the dose of manganese in the solution for growing leads to a decrease in the length of the roots. AOA SOD varied in different organs of plants of some varieties, and its more significant change in the experiment compared with the control was revealed in the roots. Judging by morphometric indicators, the Belgorodskij 100 variety was the least resistant to Mn2+ ionic toxicity, the root length of which in the control was 15.7±0.4 cm, and in the experiment 13.2±0.3; 12.2±0.1; 11.5±0.3 cm in accordance with the dose of manganese 30, 60 and 90 mg / l. According to the level of AOA SOD, the most sensitive variety was Farmer 198-12, its change of AOA SOD in the roots (% of control) was 158.8; 167.2 and 169.4% in accordance with the dose of manganese 30.0; 60.0 and 90.0 mg / l (AOA SOD in the control was 52.4±0.4%; in the experiment 83.2±2.2; 87.6±2.0 and 88.7±0.6, respectively), and in the shoots ˗ 121.0; 128.3 and 125.6 %, respectively (66.7±7.9 % in the control and 80.7±0.5; 85.6±1.4; 83.8±0.6 % in the experiment in accordance with the dose of Mn 2+).

In natural conditions of growth, forest woody plants constantly face negative environmental factors. Environmentally unfavorable impacts certainly affect the physiological and biochemical processes occurring in plants and lead to the activation of their own protective mechanisms. In recent years, methods of biotechnology (cell and tissue selection) have been increasingly used in the study of adaptive capabilities, as well as the degree of tolerance of plants to abiotic stress factors. In our work, we evaluated the specifics of the reaction of Betula pendula Roth, Betula pendula Roth var. carelica (Mercklin) L. Hmet-Ahti and Betula pubescens Ehrh. in vitro, in particular the change in the level of free proline to low-temperature stress (+4C) of different duration times. It was found that the highest value of the amino acid content in relation to the control was in the Betula pendula Roth var. carelica Merckl. clones and ranged from 163 to 206%, in the Betula pubescens Ehrh. and Betula pendula Roth clones ranged from 103 to 128% and from 101 to 131%, respectively. Uniformity was noted among the clones of Betula pendula Roth var. carelica Merckl. according to the degree of response to stress. The relationship between the ability of plants to produce more proline and successful adaptation to cold shock was revealed.
