Comportamento de Pilocarpus microphyllus Stapf ex Wardlew (Jaborandi) em diferentes tipos de solos, vegetação, e localização geográfica na floresta nacional de Carajás, Pará. Jaborandi.

Abstract

With the intense human activities on nature, it is the need of the study of plant species that have physicochemical characteristics that are of interest to society, especially in cases of endemic species, which are classified as species in danger of extinction as the Pilocarpus microphyllus (Jaborandi), which is an important resource for the pharmaceutical industry, is the only natural source of pilocarpine. This study aims to evaluate the dendrometric variables Jaborandi in different types of soil, vegetation and geographical location in the Carajás National Forest. To this were implanted 18 permanent plots on which were measurements every six months and used statistical tools to compare the results from different types of soil and vegetation found in FLONA Carajás, and in three different areas of study (center, south and north). The results revealed that in different areas there was a variation in the density of Jaborandi. It was observed that almost all the analyzed factors are influencing the diameter, height, basal area and density, that is, depending on the type of soil, vegetation and geographical location, Jaborandi shows difference in average height, diameter and basal area and density.
