SUMMARY The influence of light on germination of seeds of a number of tropical weeds was studied. The same types of light sensitivity known from seeds of plants of the temperate zone were found. In addition to the expectation that the behaviour of tropical seeds resembles that of the temperate zone, also was found that seeds of Ruellia tuberosa probably show a very fast “inverse dark reversion” and that gibberellic acid may delay or inhibit the onset of a secundary dormancy.
