Seed provenance and latitudinal gradient effects on seed germination capacity and seedling establishment of five indigenous species in Burkina Faso

The present study sought at estimating seed germination capacity and seedling establishment of five Combretaceae species. Five replicates of 20 seeds of Anogeissus leiocarpa, Combretum aculeatum, C. micranthum, C. nigricans and Pteleopsis suberosa were submitted to germination test according to seed provenance and along latitutainal gradient. Seedling plantation test concerned 25 seedlings per species and per site. Seed provenances affect only the germination capacity of C. aculeatum (P = 0.008). Latitudinal gradient influenced the germination parameters of all the species except P. suberosa (P = 0.009). The seedling capacity of establishment varied between species, along latitudinal gradient and between control and uncontrol plots (P < 0.001). A. leiocarpa, C. aculeatum, C. micranthum, C. nigricans are potentially usable in vegetation recovery program.
