Abstract
Laboratory germination tests on the seeds of 32 weed species are described. Fresh seeds of almost all the species possessed a high level of innate dormancy which could in most cases be broken by appropriate treatment. Stratification, alternation of temperatures, dry storage and seed-coat damage were effective in different species. Optimum temperatures for germination varied widely. Light was necessary for germination in some species and, in a few, germination in the light was enhanced by a previous period in darkness. Possible relevance of some results to field behaviour is briefly discussed
