Abstract

Methanol extracts of fresh tissues of ‘Mazzard’ (Prunus avium L.) and ‘Mahaleb’ (P. mahaleb L.) were examined for phenolic composition. The 2 sweet cherry rootstocks differed in 3 phenolic groups; phenolic acids, coumarins, and flavonoids. ‘Mazzard’ contained 5 acids; p-coumaric, o-coumaric, caffeic, p-coumarylquinic and chlorogenic, whereas ‘Mahaleb’ contained mostly o-coumaric acid. ‘Mahaleb’ tissues were rich in coumarin and herniarin, but these were absent in ‘Mazzard’. Three flavonoids; dihydrowogonin, kaempferol and quercetin, were found in ‘Mazzard’. ‘Mahaleb’ contained only kaempferol. These differences in phenolic composition between the 2 rootstocks seemed related to graft-incompatibility.

Abstract

Seedlings of Mazzard (Prunus avium L.) and Mahaleb (P. mahaleb L.) cherries were found to differ in phenolic and coumarin components in the leaf, stem and root Analysis by gas liquid chromatography indicated more o-coumaric acid in the leaves than in stem and roots. Bark of Mahaleb stem and roots contained coumarin and herniarin. The difference in phenolic composition in these cherry seedlings may play a role in scion overgrowth when sweet cherry cultivars are budded on Mahaleb stocks.
