    Аннотация The influence of atmospheric pollution, caused by road transport, on the physiological and biochemical,ecological and morphological parameters of common dandelion plants (TaraxacumofficinaleWiggs.l.) is considered in the article. Multiphase dependences were obtained with a change in the direction of response, under the conditions of increasing traffic, in the germination energy and the weight of seeds, ripened in inflorescences, cut off on the fourth day after flowering. In the gradient of atmospheric pollution by motor vehicles, a complex three-phase dependence of the mass of seeds in the calathide, and the energy of their germination, is observed. The extreme values of these parameters are 13-20% higher, than the control values, and they are manifested when the traffic intensity is 2100 vehicles per hour, that allows to refer the dependence data to paradoxical effects. The critical mass of viable seeds for their germination was 0.23 ? 0.007 mg, which was 10% higher, than the previous
