Abstract

Ð?. V. Spryagailo

The reproductive ability introduced kinds of Middle Dnieper cultivated dendroflora is estimated. The kinds of ergasiofity and the main ways of fruit and seed spreading is established. About of 77% of trees species, shrubs and vines used in landscaping installations in Middle Dnieper area are able to generate viable seeds. Some 24% of species and hybrids has demonstrate the highest level of adaptation to cultivation and under certain conditions could form self-sown crop. Some species of cultivated dendroflora are willfully spread and cultivated in natural ecosystems, threatening their stability and resistance. Most of the potential ergasiophytes species referred to ornithohores (29%) and anemochores (23%).
