Sažetak

Ekstenzivno gajenje vinove loze podrazumeva sve agrotehničke operacije bez upotrebe herbicida. Uzorci zemlje za utvrđivanje banke semena korova uzimani su na početku i pred kraj vegetacije. Sa svake parcele u deset ponavljanja je vršeno uzorkovanje iz sloja zemlje u međurednom i rednom prostoru. Posebno su odvajani uzorci sa dubine od 0-10 cm, 10-20 cm i 20-30 cm. Cilj istraživanja je bio utvrditi sastav banke semena korova u ekstenzivnom zasadu vinove loze, kod kojih se ne primenjuju herbicidi u cilju suzbijanja korova. U ekstenzivnom vinogradu su utvrđene 23 korovske vrste: Portulaca oleracea L., Amaranthus retroflexus L., Stellaria media (L.) Vill., Chenopodium album L., Euphorbia helioscopia L., Galium verum L., Polygonum persicaria L., Datura stramonium L., Setaria glauca (L.) Beauv., Solanum nigrum L., Vicia tetrasperma L., Stachys annua L., Geranium dissectum L., Lamium purpureum L., Veronica arvensis L., Euphorbia ciparissias L., Convolvulus arvensis L., Sinapis arvensis L., Polygonum aviculare L., Papaver rhoeas L., Viola tricolor L., Capsella bursa-pastoris L. i Ambrosia artemissifolia L. Od ukupnog broja semena dominirale su korovske vrste Amaranthus retroflexus L., Portulaca oleracea L., Chenopodium album L., Stellaria media (L.) Vill i Lamium purpureum L.
