- Аннотация: THE MODERN TRENDS PLANT RESEARCH INTRODUCTION BY THE EXAMPLE OF THE GENUS PAEONIA L. (PAEONIACEAE) 55 morphological and ornamental features of 17 species and 200 varieties of Paeonia genus introduced in the Botanical Garden of MSU were studied. Certain characters including diagnostic were chosen to be use for estimation of peonies for identification, classification, selection and use in ornamental gardening. Advisability of complex research was shown. The analysis of peonies morphology allowed to reveal the amplitude of their variability. Our researches have revealed significant polymorphism in alternation of flower parts, and also the modifications concerning reproductive organs. The analysis of alternation of flower parts did not reveal dependence of its type from an origin of cultivar and from which parental species it derives. Besides flower structure, many conservative features of peonies, such as ploidy, ultrasculpture of pollen grains and surface of seeds are subjected to variability. As a result of the work we recorded direct dependence between loss of reproductive function and occurrence of atypical structures (doubleness, fragrance) which occurs because of the increase of flower apical meristem sizes during the formation of plant organs.
