Biological Spectrum of Weed Flora and Vegetation of Raspberry Plantings in Serbia

Abstract

A timely and proper weed control imposes the need to identify the floristic composition and biology of weed community in raspberry plantings. A survey was conducted in more than 40 raspberry plantings (southwest part of Serbia) and about 85 weed species (68 broadleaf and 17 grass species) were registered. At the study area, the predominant grass weed species according to abundance and cover values were: Panicum crus-galli L., Setaria glauca (L.) P. B., Setaria viridis (L.) P. B. and Digitaria sanguinalis Scop.; and broadleaf species: Amaranthus retroflexus L., Amaranthus hybridus L., Chenopodium polyspermum L., Erigeron canadensis L., Galinsoga parviflora Cav., Glechoma hederacea L., Polygonum lapathifolium L., Convolvulus arvensis L., Calystegia sepium R. Br. and Rubus caesius L. In biological spectra of weed flora and weed vegetation dominate annual (therophytes, 26) and perennial species from hemicriptophytes life form (25).
