(Fabaceae), a real alternative to its regeneration and domestication. A trial was conducted to evaluate the effect of different doses of Acid Naphthalene Acetate (ANA) (0; 500; 750; 1000 and 1500 mg/l), the type of substrate (black forest sand and fine sand) and the size of the cuttings used ([1.5-2] and [2.5-3] cm of diameter) on the recovery of these cuttings. To evaluate the effect of different treatments on budding rate, bud burst rate and degenerate cuttings rate, Generalized Linear Mixed Models and Generalized Linear Models of the binomial family with the lme4 and nlme packages were used with the R.3.2.4 statistical software. The results showed that the application of ANA does not significantly improve the cuttings recovery. The probability of budding and budding with 0 mg / l of ANA is similar to ...

The data collected in 139 plots of 1000 m2each related to the diameter at breast (1.3 m above ground), total height, identification, and measurement of DBH relatedP. africanaspecies height. Tree-ring parameters such as Blackman and Green indices, basal area, average diameter, height of Lorey, and density were calculated and interpreted. Dendrometric settings of vegetation type and climate zone (Guinea, Sudan-Guinea, and Sudan) were compared through analysis of variance (ANOVA). There is a significant difference in dendrometric settings according to the type of vegetation and climate zone. Basal area, density, and average diameter are, respectively, 4.47 m2/ha, 34.95 stems/ha, and 37.02 cm in the fields; 3.01 m2/ha, 34.74 stems/ha, and 33.66 cm in fallows; 3.31 m2/ha, 52.39 stems/h...
