Enzyme polymorphism of antioxidant system in chronically irradiated Scots pine populations

Genetic Variability of Scots Pine Maternal Populations and Their Progenies

The genetic variability of Scots pine was investigated in six populations from Poland representing two maternal populations and their natural and artificial progenies. Thirteen enzyme systems controlled by 2 allozyme loci were analyzed using starch gel electrophoresis. Progeny populations maintained a high and similar level of genetic variation to that observed in the maternal populations. As e...

Chromosomal polymorphism in irradiated natural populations of Chironomus.

CHROMOSOMAL polymorphism occurs in many species of Drosophila and Chironomus. Evidence has been accumulated by BEARDMORE, DOBZHANSKY and PAVLOVSKY ( 1960), BATTAGLIA and SMITH (1962), and others that chromosomal polymorphic populations are superior in fitness to monomorphic populations. In most cases it is accepted that populations remain chromosomally polymorphic because the heterokaryotypes a...

Climatic Adaptation of Seed Maturity in Scots Pine and Norway Spruce Populations

Hydraulic adjustment of Scots pine across Europe.

* The variability of branch-level hydraulic properties was assessed across 12 Scots pine populations covering a wide range of environmental conditions, including some of the southernmost populations of the species. The aims were to relate this variability to differences in climate, and to study the potential tradeoffs between traits. * Traits measured included wood density, radial growth, xylem...
