CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Molecular analysis of genetic variation

Exporter la citation

Knowledge of the underlying level, structure and origin of geneticvariation within and between plant populations is crucial forscientific approaches to their utilization and conservation(Yeh,1989; Hamrick, 1993). Determinants of the level and structure of genetic variation within plant species include matingsystem, evolutionary history, life-history characteristics, population density and mechanisms of gene flow (Schaal, 1980;Loveless and Hamrick, 1984; Hamrick et al., 1992; Loveless, 1992). In addition to the within-species issues, potentially complex interactions among species must be considered(Rieseberg and Brunsfeld, 1992; Rieseberg and Wendel, 1993).Although morphological characters and various productiontraits have traditionally been used to characterize levels andpatterns of diversity, these traits alone represent only a smallportion of the genome and are also influenced by environmentalfactors, thereby limiting their utility in describing the potentiallycomplex genetic structures which may exist within and amongtaxa (Avise, 1994).
