Segetal vegetation was studied in the cultivated areas of southern Srem
with the aim of analyzing its taxonomy, phytocoenology, syntaxonomy and
phytogeography, as well as determining to what extent ecological factors
influenced the differentiation of segetal plant communities among row
crops, small grain crops and in alfalfa fields. Segetal flora was
comprised of 124 plant species, classified into 38 families, of which
Asteraceae (28), Fabaceae (10) and Poaceae (10) contained the greatest
number of species. Three associations were selected based on
phytocoenological analysis: Polygonetum convolvulo-avicularis,
Consolido-Polygonetum avicularis and Lolio-Plantaginetum majoris, as
well as five lower syntaxa (subassociations and facies). Crop type,
moisture, habitat acidity (pH), temperature and anthropogenic factors
had the greatest impact on the ecological differentiation of the studied
vegetation. The significant presence of non-native species (18) was
another consequence of the anthropogenic effects and geographic position
of southern Srem, and these, as coenobionts of segetal plant communities
and undesirable species, had a significant impact on crop yield.
