Description
Summary:After 14 days, it was observed that most of the accessesion presented high G (greater than 70%), GSI less than 2 seeds.day-1, Z with a mean value of 0,52 and AGT with a mean value of 2 days, characterizing a synchronous and rapid event. [...]the methodology used in storage is efficient for the conservation of Stylosanthes seeds in the medium term. INTRODUCTION Plant Genetic Resources (PGR) represent the basis to assist current and future generations in solving issues related to climate change, loss of biodiversity, environmental degradation and malnutrition (Nass et al., 2012; Bioversity International & CIAT, 2019). [...]there is a concern to rescue and conserve germplasm that has potential for use, with emphasis on ex situ conservation, with the formation of Germplasm Banks (GBA), which through the storage of seeds enables the conservation of genetics information of the species for a long period of time and in a small physical space (Silva et al., 2018). [...]the way of handling the GBA is essential to maintain the longevity of stored seeds even for long periods. [...]the basic organization of these banks with information such as passport data and characterization of accession; works that follow the viability and vigor in the conservation process in the short, medium and long terms; and suitable environment for storage, are essential (Veiga et al., 2012). Because storage started between seven and 13 years ago, monitoring the viability of the seeds (Araujo et al., 2014) becomes paramount in order to maintain the longevity of the germplasm and/or direct the adoption of regeneration, so that they do not suffer genetic erosion.
