bullet3 Trial 12: Provenance trial of Acacia senegal

This trial was made up of 10 provenances of Acacia senegal. The trial was established with a spacing of 4 x 4 metres in 1988, and the assessment, which took place after 5 years in 1993, included a number of vegetative and growth characters. Gum production was not measured. The provenances included a selection of Sahelian seedlots (Burkina Faso, Senegal and Sudan) and two provenances from Sind in Pakistan.

There were several highly significant differences between the provenances. The provenances from Pakistan had a poor survival and growth and were clearly not adapted to the site. The African provenances had a much better performance, and two provenances from Senegal and one from Burkina Faso had the fastest growth at the site. The dry weight production of the best provenances was almost 2 tons ha-1 y-1. There were significant differences both within the provenances from Senegal and within the provenances from Burkina Faso, documenting genetic variation within short distances.
