摘要：

A total of 120 individual trees representative of Pinus uncinata were analysed for their foliar flavonoid content. The ratio of two extracted anthocyanidins, prodelphinidin and procyanidin, is a constant. Among the flavonols quercetin, kaempferol and isorhamnetin, the percentage of quercetin discriminates the five studied populations. Its distribution conforms to the Hardy-Weinberg law, but the ratio of the two implicit alleles proves the originality of each population, and leads to the recognition of distinct chemotypes.
