The origin of variation in seed density in celery (Apium graveolens L.)
Year: 1993
Type: article
Abstract: Summary Seeds were harvested separately from the sequentially formed umbels to obtain information about the origin of variation in seed density in celery. The study involved seeds from the lowest order (primary) to the highest order (quarternary) umbels from the cvs Mars, Monarch, Selfira and Tall Utah. With increasing umbel order the percentage germination decreased and the mean germination time increased. Seed density increased with increasing umbel order, but was more highly correlated with the length of the seed ripening period which differed for each umbel order due to simultaneous harvesting. The decrease in seed density during seed development was correlated with an increase in air volume in the seeds. It is concluded that the variation in seed density in celery seed lots originated from differences in seed maturity.
