Viability of chloroleucon dumosum (benth) (fabaceae) seeds under different storage conditions

Chloroleucon dumosum (Benth) G.P. Lewis (Leguminosae-Mimosa (Currently Caesalpinioideae) - Ingeae) is a deciduous species, occurring in the Caatinga, in general fields and forests that form corridors along rivers and wetlands. It is usually called arapiraca, mahogany or white jurema. A large part of the projects aimed at the conservation and exploitation of native forest species depend on the formation of seedlings. Thus, the renewal of vegetation and the recovery of degraded areas, as well as the establishment of germplasm banks, are based on the collection and storage techniques of seeds. Based on this, the work aimed to monitor the physiological quality of C. dumosum seeds as a function of different packaging and storage conditions. The experiments were conducted at the Plant Propagation Laboratory of the Agricultural Engineering and Sciences Campus (CECA) of the Federal University of Alagoas (UFAL), located in the municipality of Rio Largo, Alagoas, Brazil. The seeds were placed in two types of packaging (permeable and impermeable) where they were stored under different conditions of humidity and temperature (normal environment and dry chamber) for eight months. Seeds placed in glass containers in the dry chamber maintained considerable physiological quality.
