dc.description.abstract In this study is investigated microsporogenesis and evolution of young microspores both three varieties of Romanian peach Amalia, Congress and Splendid and two Romanian varieties of nectarine Tina and Michaela. Within these species it was considered that at the choice of the varieties to be included the all three ripeing periods of the fruits (early, middle and late). The aim of the research consists in the knowledge of the maturing microspores steps at peaches and nectarines, regarding the development of sporoderma by reaching the final dimensions beginning from young microspores, to mature pollen. Also we had in view the selecting of peaches and nectarines varieties with resistance to very low temperatures in winter. It was studied the effect/impact of negative temperatures in winter on the successive stages of maturation microspores starting with CMP (pollen mother cells) to binucleat mature pollen of flowering buds. From the biological perspective the microsporogenesis was not disturbed by external factors and tetrad and young microspores had a normal aspect for the development phase. The pollen maturation went under normal physiological and undisturbed conditions in the line with the changing weather en_US
