Results of study of callose content and its topography in mother cells of microspores, microspores and pollen grains in terrestrial and air-aquatic S. latifolium plants growing under different water regimes are presented. The increased content of callose in the microspore walls at tetrad stage and pollen grains is revealed on the basis of fluorescence intensity and quantitative luminescent analysis of terrestrial S. latifolium plants. It is connected, probably, first of all, with the protective role of callose for preservation of water in these cells under water deficiency.
