АПОФІТИ І АДВЕНТИВНІ ВИДИ У ФЛОРІ М. ЛЬВОВА

Abstract

The synanthropic flora of the Lviv city was studied. It includes 663 species of vascular plants which belong to 382 genera and 103 families of four divisions. The families which are the most saturated of synanthropic species: Аsteraceae (15.2 %), Rosaceae (7.4 %), Poaceae (7.2 %), Fabaceae (6.8 %), Brassicaceae (6.5 %), Lamiaceae (4.8 %), Scrophulariaceae (3.8 %), Polygonaceae (3.2 %), Caryophyllaceae (3 %), Chenopodiaceae (3 %). Prevailing genera of synanthropic flora are: Bromus Scop. (1.7 % видів), Vicia L., Geranium L. (по 1.5 %), Amaranthus L., Trifolium L. (по 1.4 %), Chenopodium L., Potentilla L. і Veronica L. (по 1. 2 %), Aster L., Atriplex L., Epilobium L. і Rumex L. (по 1 %). 31 families are represented exclusively in apophytes, and 37 – are only in adventitious species. The apophytes fraction is larger – it accounts for 334 species. The adventitious fraction includes 329 species (archeophytes – 102 and kenophytes – 227 species). The largest number of adventitious species occurs along roads, railways, near garbage, on abandoned sites, on private plots. The degree of naturalization is dominated by a group of epecophytes (49.8 %), by the way of penetration – ergasiophytes – 40.4 %.
