SOROL, Claudia B et al. Bases para la conservación de las semillas de Calophyllum brasiliense (Calophyllaceae). Bol. Soc. Argent. Bot. [online]. 2015, vol.50, n.1, pp.93-106. ISSN 1851-2372.

Calophyllum brasiliense Cambess (Calophyllaceae) is a tree species distributed in Argentina in the edges of matting and hygrophilous forests of the Paraná River. Those of the riverbank have been strongly fragmented due to the increment of the flood levels caused by the Yacyreta dam, thus, this populations are at risk of being locally extinguished as a consequence of their drastic size reduction. Fragmentation can affect plant species reducing the amount or the quality of seeds produced or both. The ecological, medicinal, economic and social value of the species and the status of their populations have generated interest in its preservation. One of the strategies implemented was the storage of its seeds, which are recalcitrant. The aims of this study were to evaluate three populations with respect to their potentiality to produce seeds capable of generating individuals, and evaluate the physiological quality regarding the harvest time and the length of the storage period under four methods. The Puerto Valle population produced seeds of good quality which conserved the viability for thirty-one weeks when they were stored with endocarp, in glass bottles.
