The germinability of the Vicia sativa L. seed samples in the base collection at the Centro de Recursos Fitogene´ticos (Spain) was controlled in 1986 and 1996. The mean germination of the collection, assessed by One-Sample T Test, was higher than 85%, suggesting its viability was properly maintained along the period. However, changes in germination along the same period assessed by Paired-Samples T Test showed a slight decrease in its global germinability. More data on the viability of stored seeds worldwideincluding communication of unpublished data -are needed. Viability assays should be performed according to standard, internationally coordinated protocols and statistical analysis, within an adequate documentation system that assures the integrity of accession information.

Seed germination of seven celery cultivars was studied after storage in liquid nitrogen for I or 30 d. Cryopreservation was also carried out on pelleted and primed seeds. None of the treatments applied reduced germination percentages. T 50 (time for germination to reach 50%) significantly decreased in Florida, Utah and Istar cultivars when priming, alone or in combination with cryopreservation, was used.
