INFLUENCE OF MOISTURE CONTENTS, PACKAGE AND ENVIRONMENT ON THE VIABILITY AND VIGOR OF ?PAU-SANTO? (Kielmeyera coriacea) SEEDS
SORAYA ALVARENGA BOTELHO E JOSÉ GERALDO DE ARAÚJO CARNEIRO
The objective was to determine the best conditions for the storage of Kielmeyera coriacea seeds, a cork producing species native of ?cerrado?, know as ?pau-santo?. The seeds went throught a drying process in a store at a 42°C during 0, 3, 6, 12 and 18 hours, reaching moisture contents of 21,3, 14,2, 11,4, 9,6 and 8,7%, respectively. Afterwards, the seeds were wrapped in cotton bags and polyethylene bags (0,20mm), and kept in a cool chamber (4°C; 96% R.H.) and in a lab environment (17,5°C; 78% R.H.). After eleven months, the best way to store was obtained from the polyethylene bags, inside the cool chamber, for seeds with 8,7% of humidity wich kept their initial viability.
