Regulation mechanisms in population dynamics of segetal plants


, : Regulation mechanisms in population dynamics of segetal plants. Berichte ueber Landwirtschaft Sonderheft 0(209): 68-84

Within the last years opinions have changed concerning the role and importance of weeds accompanying the crop plant in agroecosystems. Attention ha; been paid especially to questions related to fundamentals of regulating mechanisms in weed populations. This applies as well to phenotypic adaptations within the life-cycle as to evolutionary tendencies of a longer distance caused by changing agricultural practices. Promising knowledge concerning the course of population dynamics are gained by modelling and simulation experiments within the last time. Nevertheless to use the results of these attempts successfully additional information are needed by extending the pool of available primary dates.
