VILLALBA-BRIONES, Ricardo; JIMENEZ, Edwin Rolando; REZABALA, Allison  y  AGUIRREBENGOA, Martin. Effect of conservation temperature on Cavanillesia platanifolia seed viability. La Granja [online]. 2024, vol.40, n.2, pp.65-77. ISSN 1390-8596.  https://doi.org/10.17163/lgr.n40.2024.04.

Cavanillesia platanifolia is a tree species distributed in the tropical dry forest ecosystem threatened by the fragmentation and loss of its habitat. Reforestation is thus to be considered for its conservation. The ex situ production of young individuals is key for any reforestation plan. In this study, we compare the recruitment capacity in nursery of two seed conservation treatments: cold conservation vs. conservation at ambient temperature. The emergency rate increased and the seedlings grew more vigorous in cold-preserved seeds. In addition, seedling mortality was significantly reduced in cold-preserved seeds, which we believe is due to a slowdown in seed ageing and a decrease in pathogenic activity. This easily replicable and economic nursery cultivation methodology can be incorporated into the potential reforestation plans of C. platanifolia, as well as to other threatened plant species of the neotropic with seeds of similar characteristics.
