The natural reconstitution of indigenous forestry species stock in degenerated areas is a time-consuming processo However, the intervention by means of artificial regeneration may represent an improvement in order to the forestry reconstitution. This work evaluates the efficiency of different implantation systems of the heart of palm (Euterpe edulís) in secondaryforests. The following treatments were set up: 1) fruits on the soil surface; 2) fruits sowed; 3) seeds on the soil surface; 4) seeds sowed; 5) seedlings and; 6) young plantlets. Evaluations done 40 and 52 months after the implantation took in account plantlet width at the soil levei, height of leave insertion, survival rate and leaves number. The results showed a low survival rate forthe treatmentswith seedlings and young plantlets and high survival rates in the other treatments. The analysis of these data indicates that the utilization of seeds or fruits spreading on the soil surface are the most efficient systems for the implantation of heart of palm. However, in the case of restrict seed or fruit availability the other systems may apply taking in account the additional costs.
