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.

Uapaca kirkiana phenological phases and effect of fruit thinning on fruit traits in Malawi

Exporter la citation

Uapaca kirkiana is one of the most preferred indigenous fruit trees in many countries of southern Africa, including Malawi, but it has a long juvenile phase. In order to shorten this juvenile period, grafting is widely applied. High fruit load, small fruit size and premature fruit abortion have been observed in mature U. kirkiana. This high fruit load may lead to alternate bearing and/or production of small fruits in the next fruiting season. This study was undertaken at ICRAF-Makoka in Malawi with the objectives of assessing (1) the effect of fruit thinning on U. kirkiana fruit yield and size and (2) establishing leaf and fruit phonological phases of U. kirkiana annual growth cycle. Immature fruits were thinned manually to one fruit per cluster along the tree branch either (1) 5 cm, (2) 10 cm, or (3) 15 cm apart. Leaf, flowering and fruiting phenological phases (onset and end) were established. Fruit thinning significantly (P
