Coffee is one of the main agricultural commodities in the country, and it is important to conservation of plant material for breeding programs. Cryopreservation is a promising alternative for preserving in the long-term the germplasm of species considered recalcitrant. However, studies should be performed to achieve maximum survival of seedlings after immersion in liquid nitrogen. The objective of this work was to find a cryopreservation protocol for storing seeds of Coffea canephora, studying two methods of cryopreservation, slow and fast cooling. Seeds were subjected to drying in silica gel up to the water content of 0.25 g g-1. In the first experiment, dried seeds were subjected to treatments of slow cooling at speeds of -1 ºC min-1,-3 ºC min-1 and -5... |
