    ENGLISH ABSTRACT: This study describes (a) Identification of the main anthocyanin pigment in the skin of the 'Fuji' apple cultivar and in the pear cultivars 'Bon Rouge' 'Forelle', Red d'Anjou', 'Rosemarie' and 'Flamingo', (b) an investigation of the effect of on-tree bagging on anthocyanin pigment accumulation in the skin of the 'Fuji' apple cultivar by means of high performance liquid chromatography (HPLC) technology. (c) an investigation of the influence of cold storage and ripening on anthocyanin concentration and accumulation in the skin of the pear cultivars, 'Forelle', 'Rosemarie', 'Flamingo', 'Bon Rouge' and Red d'Anjou' pear cultivars by means of HPLC technology and (d) an investigation of the level of induction of dihydroflavonol 4-reductase (DFR) gene in 'Fuji' apple cultivar during bagging trial, through mRNA studies.
