Richter A. Biochemical basis of the phylogenetic links in the subfamily Prunoideae Focke

Object - laws of communication of biochemical characteristics of fruits of some representatives of subfamily Prunoideae Focke, determined theis evolutional level and phylogenetical relationship; the purpose of work - to find the character of changeability of biochemical characteristics of fruits and the laws of inheriting determined their links in modern varieties and hybrids in connection with phylogeny and selection on the example of subfamily Prunoideae Focke, differed by systematical position; methods - photoelectrocolorimetry, gas-liquid chromatograhy, liquid chromatography and others emploging in biochemistry and taxonomy of plants with variational, dispersional, correlational and clasternal analysis were used; novelty - for the first time the laws of communication of biochemical characteristics of fruits (Persica vulgaris, Persica vulgaris var.nectarina, Armeniaca vulgaris, Prunus cerasifera, Cerasus avium, Amygdalus communis), which could be used in practical selection for further improving offruit quality of new varieties have been given; tendency of changing of biochemical composition of fruits during the breeding work with interspecific and innerspecific hybrid material has been determined; results - the comparative analysis of changing of fruits characteristics of subfamily Prunoideae Focke on different levels of phylogenetic system (wild species - modern variety) and the scheme of possible phylogenetic relations of genus of this subfamily have been given; branch - experimental botany, selection of stone fruits plants
