The influence of various lead tetraethyl concentrations (mixture added to petrol as antiknock agent) on the growth and development of Funaria hygrometrica L. spores and of Marchantia polymorpha L. gemmulae was investigated. An inhibitory effect of the concentration applied was noted on germination and growth of spores and gemmulae development. Lead tetraethyl produces disturbances In the development of these plants, gradual degeneration of chloroplasts occurs and inhibition of growth leading to profusely branched "dwarf" forms. The disturbances are largely reversible
