Knowledge on the storability of seeds allows the establishment of suitable conditions forkeeping viability after harvest and elaboration of programs for the conservation of germoplasmabanks in the long term. This study aimed to classify seeds of Cryptocarya aschersoniana, Nectandranitidula, Ocotea odorifera and Persea pyrifolia in relation to the storage behavior based on theirtolerance to desiccation and low temperatures. Viability and moisture content were accessed forfreshly-processed seeds; for seeds desiccated; after 90 days for fresh seeds and stored at 5 °C packedin semi-permeable package and after 90 days for dry seeds stored at 5 °C and -18 °C with the impermeable wrapping. Statistical analysis was performed by comparing the overlaying confidence Classificação fisiológica de sementes de espécies florestais pertencentes à… 30intervals of the means of germination percentage for each species. The seeds of species studyed wereconsidered recalcitrant because loosed viability after desiccation. |
