Storage of seeds from tropical legumes used in cuban livestock production systems
The effect of storage duration, under farm conditions, on the deterioration of seeds from Erythrina berteroana, A lbiz ia lebbeck, Gliricidia sep ium and Bauhinia purpurea, was studied.For each species, a simple classification design was used with four replications of 100 seeds each.The viability ( ％ ) and germination ( ％ ) were determined, which analysis was carried out through the variance analysis and the matrix of multiple comparison of means of Student Newman Keuls (SNK) of SAS．Germination in Erythrina showed a significant increase during the study (from 20％ in 0 month to 68％ in 12 months), while A lbiz ia exhibited variable performance ; in both species the viability decreased, but even in the final evaluation it still exceeded 80％.The age of the seeds from Erythrina and A lbiz ia was determined to have influenced the impermeability of the seed coats and thus their high survival.Germination and viability values for Bauhinia and Gliricidia were similar and decreased significantly during the storage.Bauhinia seeds evaluated at 11 and 9 months had lower quality while Gliricidia seed reached physiological death at 7 months confirming both species deteriorate at an accelerated rate during storage under ambient conditions.
