EFFECTS OF HYBRIDIZATION ON LEAF CONSTITUENTS IN GENUS SALIX

The distribution of leucoanthocyanidins, phenolic glycosides and piperidine-based imino-acids has been studied in the leaves of Salix species and hybrids. When both parents contained either leucocyanidin or leucocyanidin and leucodelphinidin, the hydrid contained the same compounds. When, however, species containing leucocyanidin were crossed with species containing leucocyanidin and leucodelphinidin, the hybrids did not give a uniform result. Phenolic glycosides were detected in all species and hybrids tested, but no obvious taxonomic pattern was noticed. Pipecolic acid was found in many of the leaves tested, but often the yields were low. © 1970.
