Abstract
ABSTRACTBioclimatic characteristic of weeds in the city Cordoba’s green belt. Part I – Polygonum aviculare “Knotweed”, Polygonum aviculare is oneof the most common weeds in the winter-springperiod in the horticultural zone of Cordoba greenbelt. In order to know the phenology and climaticrequirements of the species in each stage of its lifecycle, an experiment was conducted in one of thegreen belt farms located in the NE of Cordobaoutskirsts for three years (1988, 1989, 1990).Different phases and sub-periods of this life cycle,phenometric parameters (plant height and density)and meteorological observations were determined.The experiment enabled to establish the stationalflow of emergency and corroborate the winter-spring ecological type of the weed. These aspectsof the bioecology, phenology and bioclimatologyare necessary tools when implementing anintegrated system of weed control. Key words: Weed, emergency,phenology, bioclimatology.
