Physiological quality of Amburana cearensis (Allemão) A.C. Smith seeds stored

Abstract

This work aimed to determine the best conditions and storage periods adapted to conservation of seed vigor for Amburana cearensis (Allemão) A.C. Smith. The experiment was conducted at the Laboratory of Analysis of Seeds (CCA/UFPB), using an entirely randomized design. The treatments consisted of A. cearensis seeds packaged in: paper Kraft bags, bags of cotton and foil aluminum, two storage conditions: room temperature and humidity conditions and refrigerator for 270 days. The evaluated characteristics were: moisture content, percentage of emergence and emergence speed index (ESI), seedling length, and seedling dry matter. After 270 days of storage the emergence of A. cearensis seedlings of conditioned in aluminum packing and stored at laboratory was of 68%. The emergency and the vigor of A. cearensis seeds are conserved, with efficiency, in all the storage conditions and packings for 90 days; and under environmental conditions in packing of aluminum for 180 days.
