Résumé : This study aimed to analyze the berry location and maturing within the plant architecture for two planting densities combined with two planting patterns in a first production year. Non destructive measurements of coffee plant architecture (cv. IAPAR 59) were performed on plants grown in two plant densities (6,000 and 10,000 plants ha-1) and planting patterns (square – Q or rectangular - R). The number of phytomers and length of the plagiotropic axes were linearly related to their rank on the trunk. In rectangular PP, the competition between plants in the row promoted the apical dominance more than in square PP. In first production year, the berries were situated close to the trunk in horizontal directions, and in lower layers in the vertical plant profile. Our results of total berry production per ha-1 argue in favor of very dense plantation with a square planting pattern. However, further observations are needed to check that canopy closure during the following years, and Arabica coffee biennial production will not reverse the observed trends.
