Physiological studies of woody plants

The Laboratory of Plant Physiology was founded at the Forest Institute in 1944 under the supervision of a member of correspondent USSR Academy of Sciences L.A. Ivanova. During this time, the laboratory studied the water, light conditions and carbon balance of the forest in different forest zones. The dependence of the number and spectral composition of PARs under the forest canopy on the throughput of the canopy of the forest stand was investigated. The physiological mechanism of drought tolerance of trees in the steppe zone has been studied. It has been shown that there are various ways of adapting tree species to drought. The joint existence of species with different types of adaptation of trees to arid conditions (for example, oak, fluffy ash and small-leaved elm) reduces the life of plantings. Artificial shading studied the effect of light deficiency on growth, leaf anatomy and carbon metabolism in seedlings of different species and revealed a physiological mechanism shade tolerance...
