Features of Water Exchange of Pinus nigra subsp. pallasiana in Conditions of Southern Coast of Crimea
Year: 2020

The eco-physiological reaction of Pinus nigra subsp. pallasiana on the impact of extreme environmental factors was studied; optimum zones and threshold values of soil moisture, temperature and illumination that limits photosynthesis and transpiration of this species in the conditions of the southern coast of Crimea were determined. The optimums of the studied parameters were found: En = 25-50 mg / (m 2 s), I = 450-1000 mol/(m 2 s), Pn = 8,5-10 mol/(m 2 s), Ws = 55-70% FC. As an indicator of the
