Considering that soil water availability influences plant water status and total metabolism, soil conditions and altitude are also expected to be important for the regulation of plant reproductive and vegetative activities over time. The aim of this study was to investigate the effect of climatic factors and altitude on the phenology of Entada africana and Tephrosia vogelii in three altitudinal zones of the Bambouto Mountains, West Cameroon. Materials and Methods: Phenological (flushing, leaf fall, flowering and fruiting) data were monitored monthly in the dry season and every 2 weeks in the rainy season from October, 2012 to September, 2013 for 120 trees of two tree species (60 trees for each species and 20 in each zone) in three altitudinal zones: The lower zone (1100-1600 m), the mid-zone (1600-2000 m) and the upper zone (above 2000 m). Results: Each species phenological patterns were alike and marked by seasonality on the phenophases in the same zone. However, the frequency, peak and intensity of the phenophases in the three altitudinal zones were distinct. Leaf initiation activity in E. africana and T. vogelii were associated with maximum temperature in dry season. Flowering activity started in the rainy season. Fruit initiation were associated with rainfall in rainy season, the dehiscence of fruits was completed in dry season. Precocity of leaf-initiation in the dry season and delayed of flowering, fruiting in the rainy season in response to the effect of climatic conditions and altitude was observed in the upper zone. Conclusion: Climate and altitude were the important factors affecting phenological patterns in tropical mountain tree species.]]>Haugaasen, T. and C.A. Peres,200537620630Van Schaik, C.P., J.W.
