Germinação de sementes de pimenta longa (piper hispidinerviumc.dc.)

Abstract

In 1990, based on the existing information in the Amazonian aromatic plants database created by the Goeldi Museum, a study of the production system of Pimenta Longa began, with field experiments and chemical monitoring of the essential oil of the plant in various stages of growth. The proposal of the study of Piper hispidinervium was based on the search for new sources of safrole, whose content in this plant is above 90%.The present work approached the establishment of germinability and vigor in seeds of Long Pepper with the objective of passing on the information obtained, to small farmers of the region. Seeds from the state of Acre were used, from selected matrices that presented higher levels of safrole. Seeds were mixed with carbonized rice straw to facilitate handling. This mixture was planted in plastic trays with untreated soil substrate and germinated in a greenhouse under ambient conditions with daily irrigation. The results showed an initial germination rate of around 43%, with vigorous seedlings, since the mortality rate was very low throughout the experiment.
