title: Features of photosynthesis and water regime of &lt;i&gt;Quércus pubéscens&lt;/i&gt; Willd. in the conditions of autumn dry of the Southern Coast of the Crimea
abstract: For Quércus pubéscens Willd. the zones of optimum and threshold values of soil moisture, temperature, illumination, limiting photosynthesis and transpiration, were determined. The dependences of the rate of net photosynthesis (P n ) and the intensity of transpiration (E) on stomatal conductance (g s ), leaf temperature (T l ) and soil moisture (W s ) are shown. The relationship between the speed of the xylem flow in the plant shoot (Sf, Rel. units), the change in the diameter of this shoot (d, m
