摘要

Thaumatococcus daniellii is a perennial African wild edible plant. Fruit arils from natural populations are the source of the protein sweetener, thaumatin. There are relatively few documented examples of its cultivation, however it has great potential as an intercrop for cultivation under rubber or cocoa. Across the species range there is notable diversity in leaf and fruit morphology. In this study, T. daniellii populations from four provenances in Ghana and Cameroon (separated by the Dahomey Gap) were compared for leaf and fruit morphology in situ and in an experiment using plants grown from sampled rhizomes planted under rubber in a single location in Cameroon. When collected rhizomes from four provenances were planted at one location, the samples from the local provenance produced the largest plants and fruits, and there was less morphological variation between samples from different provenances than was recorded in situ. In situ morphological differences were notable between north–south separated provenances in each country. Fruit collected in situ was analysed for aril thaumatin content and significant variation was found between provenances (1.08–2.00%). Amplified fragment length polymorphism (AFLP) was used to assess genetic diversity among the four provenances and 54% of loci were polymorphic. Cluster analysis of AFLP data separated samples of T. daniellii according to geographical origin. Maximum genetic diversity was found between provenances separated across the Dahomey Gap.
