Distribution and state of populations of Staphylea pinnata L. in the Right-Bank of Forest-Steppe

Abstract

Objective — to study the modern area of Staphylea pinnata L. in the Right-Bank of Forest-Steppe, the conditions of localities and population characteristics of this species in the new localities in the south part of the Eastern Podillya. Material and methods. Field studies were conducted in 2008—2016 on the Transdniestrian part of the Eastern Podillya (territory of the Vinnytsia Region). Results. According to literary sources, herbarium collections and our researches in the Right-Bank of Forest-Steppe, the chorological features of S. pinnata in the region were generalized. Two new locations of S. pinnata were identified. The conditions of settlement and the state of 3 natural and 2 cultiogenic populations were investigated. Conclusions. During all time of floristic studies of the territory of the Right-Bank of Forest-Steppe, 28 localities of S. pinnata were discovered here. Some of them are cultivenous. Four localities are isolated and require confirmation. The studied populations of S. pinnata have had a full warehouse and are mature and have specific regional features. It is established that in artificial forest plantations S. pinnata multiplies well with seeds and forms populations, similar in age structure to natural ones.
