摘要: The cuticular wax layer on silver birch (Betula pendula Roth) leaves is rich in cyclic secondary metabolites that provide defense against various environmental factors. Micropropagated trees from the southern (60°N), central (62°N), and northern (66°N) latitudes of Finland were grown a common garden setup quantified for variation leaf surface other traits, their association with genotype provenance was studied. 12 genotypes studied differed greatly quantity metabolites, both individual flavonoid triterpenoid aglycones overall metabolite profile. Qualitative differences observed one present single (R3). variance explained by low (between 1% 36%) most but profile showed clear separation provenance. contents two alkyl coumarates, reported first time waxes, displayed a...
