✦ Synopsis

Heterozygous red leaf peach (Prunus persica (L.) Batsch) shoots were implanted on media with varying nitrogen and carbohydrate regimes to identify a combination which elicited maximum anthocyanin production in explants. A medium with relatively low nitrogen (5mM NH4+ and 10mM NO3_ ) and high sucrose (234mM) was most effective in stimulating anthocyanin production. Sucrose was more effective as a carbon source than glucose, fructose, or starch under given nitrogen levels. The major anthocyanin in red leaf peach was tentatively identified as cyanidin 3-glucoside based on PC and HPLC analysis.
