The results of experimental evaluation of indicators of water regime the leaf blades seven species belonging to the genus Syringa L. six parameters: water deficit, the total water content, water loss, water-holding capacity, the content of «movable water», the average speed a differential water losses.Presents brief characteristics of all investigated species of lilacs.By to data provided by Orenburg Regional Centre for Hydrometeorology and Environmental Monitoring are described climatic conditions for the city of Orenburg during the growing season for the past 5 years.The total water content of leaves, water-holding capacity are defined by the method of NA Gusev content «movable moisture» in leaf blades – by the method V.A Tarenkova, L.N Ivanova the average speed a differential water losses – by the method V.I Avdeev.An assessment of the degree of drought tolerance species of lilacs in the conditions of sharply continental climate (for example, Orenburg).
