Influence of pre-sending treatment of seeds by new protective and stimulating composition on physiological parameters of development of seedlings of spring wheat is considered at normal water supply and in conditions of water deficiency. It is established, that application of film-forming compositions promoted: increase of activity of proton pumps of roots, increment of output of components of nucleotides metabolism from cells of leaves and roots of wheat seedlings at a room temperature, at the raised temperature the stabilizing effect of the studied preparations on plasmatic membranes of cells of leaves and roots was observed at normal water supply and in the conditions of a water deficit. It is shown, that the studied protective and stimulating compositions of insufficient water supply promoted increase of activity of amylase in sprouting seeds of wheat.
