Storage of Calophyllum brasiliense Cambess. seeds.

چکیده
Calophyllum brasiliense is a species native to Brazil and has potential for use in the timber industry, in the reforestation of degraded areas, besides having medicinal properties. Its propagation is mainly by seeds which, depending on their recalcitrant characteristics, leads to difficulty in conservation, due to changes in its physiological potential during storage. Aiming to contribute to the expansion of its cultivation, rational use and conservation, the objective of this study was to investigate the behavior of C. brasiliense seeds during storage. Different packings (paper, aluminum and polyethylene) and environmental conditions (room temperature and cold chamber) were quarterly tested over 12 months, by evaluating germination viability and vigor. Based on the results, it was concluded that packaging in polyethylene and freezer storage provided the best conditions for the conservation of seeds, keeping them viable for a period of nine months.
