Flavonol and Phenolic Acid Composition of Sweet Cherries (cv. Lapins) Produced on Six Different Vegetative Rootstocks
The effect of rootstock (‘ MaxMa 14’ , ‘ Weiroot 13’ , ‘ PiKu 1’ , ‘ Weiroot 158’ , ‘ Gisela 5’ and ‘ F 12/1’ ) on phenolic acid and flavonol content of “ Lapins” sweet cherry was investigated. Phenolic acids and flavonols were isolated from sweet cherries and analysed by using reversed phase high performance liquid chromatography (RP-HPLC). The major phenolic acids in sweet cherries were neochlorogenic acid (18-50 mg kg– 1), chlorogenic acid (19-62 mg kg– 1) and p-coumaric acid derivatives (15-125 mg kg– 1). The amount of flavonol quercetin-3-rutinoside (8-37 mg kg-1) was significant as well. There are significant variations in the phenolic compound content among sweet cherry fruits grown on trees grafted on different vegetative rootstocks. The significantly higher chlorogenic acid, neochlorogenic acid, p-coumaric derivative and quercetin-3-rutinoside contents were found in sweet cherry fruits grown on trees grafted on ‘ Weiroot 13’ and ‘ PiKu 1’ rootstocks. Sweet cherries produced on trees grafted on other rootstocks had significantly lower phenolic compound content.
