Summary
The authors present the development of the Pau rosa (Aniba duckei Kostermans) in three distinct experimental parcels in two plots under the primary forest shade by cutting the lower undestorey, and the third under the shade of the Caroba (Jacaranda copaia) plantation. The authors arp studying the species diameter, height and volume growth with different types of propagative material: natural regeneration seedlings and those obtained from seeds (without leaves, with leaves and stump with roots). We are determining the average and periodical annual increment in height, true volume with bark/hectar, increment/hectar/year, and the average survival percentage in each parcel. The authors are concludling that a greater quantitative development of Pau rosa com be obtained if the plantation had been given a greater percentage of illumiation. We suggest that the plantation be under the natural forest shade, already exploited economically, with the conduction of the number of the remaing trees that give shade and controling the height of the plantation in terms of 12 meters; we also suggest utilizing the thin branches and leaves from which the essencial oil and linalol can be extracted in greater productivity, without destroying the tree a practice which is used till this day.
