Reforestation dry tropical forests (DTF) has several challenges that need to be overcome. In this perspective, this study evaluated the performance of Cenostigma microphyllum seedlings inoculated with arbuscular mycorrhizal fungi (AMF plants) for 2 years after transplanting to the field with different rainfall intensity. AMF plants showed the highest gs values in both plots. These plants in wet plots stored more soluble sugars in their stems and roots, whereas root tissue was chosen under the dry plot. AMF plants had more phosphorus than Control plants in dry plots. Furthermore, AMF plants were 24% and 27% larger than Control plants in wet and dry plots, respectively. AMF plants root diameter was 25% and 18% greater in wet and dry plots, respectively, than in the control plants. Thus, the AMF plants showed higher main root biomass in both plots than the Control plants. The results of this study confirm that inoculation of C. microphyllum seedlings during germination confers a physiological advantage to these plants in field conditions after transplanting, regardless of water availability in the plot, even after two dry seasons. This can be a useful tool for recovering deforested areas in DTF.
