Korovna flora okopavina Hercegovine

On 25 research localities, overall 50 species of vascular plants from total of 25 families was noted. The highest share had family Asteraceae (10 species) and Poaceae (5 species). The analysis of biological spectrum of association Panico-Portulacetum oleraceae Lozanovski 1962 terophyte-hemicriptophyte character can be determined, with slightly higher share of terophytes, and smaller share of hemicriptophytes, resulting from exclusively mechanical measures of weed control without herbicide usage. In areal spectrum of association Panico-Portulacetum oleraceae Lozanovski 1962, 7 groups of flora elements were asserted ; among which elements of wide- spread dominate. 32 plant species appertain to the cosmopolite group of flora elements. Constituent associations Panico-Portulacetum oleraceae Lozanovski 1962. 50 weed species appertain arable crops in Herzegovina, presenting certain floristic affluence in respect to the same association described for other localities. Special emphasis has to be set on species common for all localities which are the typical species of syntaxonomic units (association, alliance, order and class): Portulaca oleracea L., Echinochloa crus-galli (L.) Beauv., Setaria glauca (L.) Beauv., Amaranthus retroflexus L., Chenopodium album L. and Solanum nigrum L. The most common type of strategy in weed flora is R (28.00%), folowed by plants of CR strategy (16.00%).
