The Icatu cultivar presented higher stem diameter, higher root and shoot development, showed by the increasing dry weight. The cultivar Mundo Novo showed the some shoot development, but small root development, similar to the Catuaí cultivar. The Arábica cultivar showed the lowest root and shoot development. A high correlation was found between the stem diameter and shoot and root dry weight. There is also a positive correlation between shoot and root dry weight.
