چکیده
Quillaja saponaria is a sclerophyllus evergreen tree species distributed from 30° to 38° S in Central Chile. In this wide distribution it expected that the exhibits phenotypic plasticity morphology of leaves associated climate variation; however, information on topic still scarce. We studied leaf variation and its relationship with temperature, precipitation, aridity 85 stands Q. throughout natural species. The results show basal diameter petiole, number secondary veins, principal vein increased precipitation decreased aridity, while length, relative length petiole temperature. This confirms for foliar characters related climatic variables indicating an adapting capability range environmental conditions which grows.

متن کاملGenic Variation in Natural Populations
By characterizing the struggle to measure variation as a struggle between two opposing views, the classical and balance theories of population genetics, I have in part obscured the underlying problem of making a functional whole out of theory and observation. Suppose that the experiments of Wallace and of Mukai had proved beyond any reasonable doubt that new mutations were, on the average, hete...
