Abstract :
Research on synanthropic flora was conducted on the strawberry plantations
in Central Poland (surroundings of Skierniewice). In 2007-2010, 104
phytosociological releves were taken on plantations – in herbicide fallow, tillage
places, and mulched places. The same number of releves was taken in
surroundings of plantations – trodden and rutty places and roadsides. In the
plantations examined, the occurrence of 127 species belonging to 30 botanical
families was noted, out of which Asteraceae (17%), Poaceae (15%), Brassicacea
(11%), Fabaceae (9%) and Polygonaceae (8%) were represented most
numerously. 61% of species found in the plantations occurred occasionally or
rarely. 21%, among others Equisetum arvense, Polygonum aviculare,
Chenopodium album, Amaranthus retroflexus, Stellaria media, Capsella bursapastoris,
Geranium pusillum, Convolvulus arvensis, Viola arvensis, Galinsoga
parviflora, Cirsium arvense, Taraxacum officinale, Poa annua, Echinochloa
crus-galli, occurred frequently or very frequently in the herbicide fallow and
tillage places. They were recognised as the most significant strawberry weeds.
The most numerous group in the plantations constituted of therophytes (64%),
which predominated over hemicryptophytes (20%) and geophytes (11%).
Apophytes – native species (48%) predominated over archeophytes (39%) and
kenophytes (9%). Within the vascular flora of the plantations examined, segetal
species (43%), ruderal species (20%) and meadow species (14%) were
predominant. Among the 48 species noted in the plantation surroundings
therophytes (48%) predominated over hemicryptophytes (35%) and geophytes
(13%). In trodden and rutty places and roadsides, apophytes (60%) predominated
over archeophytes (25%) and kenophytes (15%). Ruderal species (50%) were
more numerous than meadow species (15%) and segetal species (8%).
