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.

Preliminary survey of clonal variation in rooting of Allanblackia floribunda leafy stem cuttings

Exporter la citation

Clonal and cutting stem morphology variations in rooting ability were simultaneously examined in Allanblackia floribunda Oliv. using leafy stem cuttings in two experiments. The hypothesis tested is that clonal variation in rooting percentage is due to variation in cutting morphology. Each of the four replicate blocks used per experiment consisted of 18 treatments from two crossed factors, diameter or length × clone, making a total of n = 216 cuttings (3 cutting lengths (3, 4, and 5 cm) or diameters (2, 3, and 4 mm) × 6 stumps (clones) × 12 cuttings, as each experimental unit consisted of 12 cuttings). The cuttings were used for rooting in nonmist propagators. No clone × cutting diameter and clone × cutting length interactions (P = 0.293 and 0.513, respectively) on rooting percentage were found at the end of the study. Highly significant and significant clonal variations in rooting percentage were noted throughout the experiments. Results from this study reject the hypothesis being tested. Finally, further work should be done on the effects of physiological status of the cuttings and clonal variation in this species.
