CONSERVAÇÃO DE SEMENTES DE Inga laurina (Sw.) Willd.

Abstract

The species Inga laurina (Sw.) Willd. Fabaceae family, popularly known as ingá, has wide distribution in Brazil has quality wood, fruit with sweet pulp, and can be used in the restoration of riparian forests and areas of recovery degraded. Faced with the above, and the importance of the species, the aim of this study was to evaluate the physiological quality of seeds I. laurina stored under different conditions. The experiment was conducted at the Seed Analysis Laboratory of the Center of Agricultural Sciences of Universidade Federal da Paraíba in a completely randomized design with the treatments distributed in a factorial 3 x 6 (forms: seeds inside the fruit, seeds out of the fruit with sarcotesta and seeds out of the fruit without sarcotesta) and storage time (0, 7, 14, 21, 28 and 35 days). The variables evaluated were: water content, percentage, first count and germination speed index, primary root length and shoot, dry weight of roots and shoots. The conservation of I. laurina seeds within the fruit provides maintenance of viability for a longer period of time while stored outside fruit seeds with and without sarcotesta has its potential reduced germination and vigor at the beginning of storage.
