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.

Genetic variation in apical dominance of Cedrela odorata seedlings in response to decapitation

Exporter la citation

Cedrela odorata L. ("Spanish Cedar"; Meliaceae)is a valuable timber tree native to central and Southern America (LAMP, 1968; PENNINGTON, 1981), often grown in combination with coffee or cocoa in agroforestry systems. However, attempts to establish the species in plantations in areas within its natural range have met with repeated failure,largely because of attack by shoot boring moth larvae (Hypsipyla spp).(NEWTON et al.,1993a). Shoot borers destroy the terminal shoot, resulting in a highly branched or forked tree of little economic worth (GRIJPMA, 1976; NEWTON et al.,1993a). Evidence from performance and progeny test of C.odorata indicate that some gynotypes may display tolerance of the pest (GRIJPMA, 1976; NEWTON et al, 1993b) by displaying strong apical growth of the leading shoot after attack (CHAPLIN, 1980;VEGA,1976). Although such a characteristic is clearly of great potential value,the physiological and genetic basis of this pattern of response is not well understood.
