Comparative introduction study of Syringa vulgaris L. cultivars in the conditions of a moderately continental, continental and conditionally subtropical climate of the Mediterranean type

Abstract

The article presents the results of a comparative introduction study and cultivar evaluation of 7 of common lilac cultivars in the collections of three botanical gardens (the Nikita Botanical Gardens, the Central Siberian Botanical Garden and the Donetsk Botanical Garden) located in zones with conditionally subtropical, temperate continental and continental climate. It is established that the cultivars retain their decorative features in the conditions of introduction and show ecological plasticity, increasing their growing season with an increase in the vegetation period, as well as reducing the area of the leaf blade with a decrease in the average annual precipitation.
