  • Sustainable plant resilience
    Victor AKOA
    Plants that are phytosedentary have built up over the millennia a resistome capable of perpetuating their life in the globosphere. This resistome, whether transmissible or not, defines lasting resilience. The knowledge of the passive or active action of the vertical or horizontal aspect of the resistance, will allow to better explain the origin of the defense mechanism apart fr...

  • Microclimate and physiological characteristics of Conilon coffee trees
    Andre Vasconcellos Araujo
    There are few studies on coffee intercropped with rubber and banana trees, so studies on shaded coffee are important for a better understanding of the systems. The aim was to study the effect of intercropping with banana and rubber trees on Conilon coffee trees, and to characterise the microclimate. This project was carried out on three plantations: 1) Conilon coffee (Coffea ca...
