Acad. Sci. there was observed displacement of plants sexualization under the impact of exogenous (climatic) factors both in the direction of androdiecy, and gynodiecy. Four types of inflorescence have been defined depending on flowers sex and their quantitative correlation in an inflorescence. The reduction of different degree of stamens filaments, pollen sacs and pollen, pistils and stigmas was observed. The highest indices of pollen germination in M. alba are found in form №11 — 52,6 %, the saccharose concentration in the nutrient medium being 25 %. Selection forms form full–grained seeds with high germination energy of 91–98%. There have been
defined introduced plants with early, late and stretched forms of fruitage.
