Conifers from the coldw, seed maturation has low probability, early survival is low and growth is slow. Northern Scots pine populations are genetically differentiated from southern Finnish ones in many of the traits that confer adaptation to harsh conditions, such as cold tolerance and timing of bud set in the fall.

Worldwide latitudinal clines for the alcohol dehydrogenase polymorphism in ,: What is the unit of seke allozymes, inversions and quantitative traits. The identical nature of these clines on the various continents, both on the Northern and Southern Hemispheres strongly suggests adaptation to specific stress factors. The alcohol dehydrogenase . polymorphism shows high frequencies of the . allele in

Stress and metabolic regulation in ,that are to some extent compensated by altered gene expression. The fact that different genotypes may respond differently to environmental stress may be of key importance to the maintenance of genetic variation in metabolic traits. Here we quantify a set of metabolic characters in genetically define
