Abstract
On a test plantation of 35-year-old intraspecific hybrids of Siberian cedar in the Voronezh region, the influence of plants location on the plantation, which determines the volume, density of the green part of the crown and soil moisture, on their growth and physiological state was established. It was especially noticeable in the forest-steppe in the extremely hot summer of 2021. Within 36 days at a temperature of 30–36 °C, as a result of intensive transpiration, increased respiration and a sharp decrease in photosynthesis, the cedars dried up from dehydration, growing on the edge of the plantation and inside it, in the “windows” of the canopy, on a large illuminated area, with low growth energy and with a large evaporating surface of the crown. The hybrids remained viable, vigorously growing in dense standing on constantly shaded, sufficiently moistened soil, with a relatively small length and density of the photosynthetic surface of the crown.
