The effects of ploughing or removal of an aboveground vegetation on the germination and emergence of Amaranthus patulus Bertol. were studied in a field in the second year of secondary succession. During the study period from late March to early July, the seedling emergence of this species was to a large extent dependent on treatments that lead to make bare ground. These field observations corresponded with the results of the laboratory studies which showed that germination was strongly inhibited under a simulated leaf canopy.
