This study aimed to evaluate the physical and physiological quality of coriander (Coriandrum sativum) seeds harvested manually and mechanically, as well as the physiological and sanitary quality of whole and split seeds stored in different containers and storage conditions. 'Verdão' coriander seeds were harvested manually and mechanically. After conditioning, seed purity was determined, and the seeds were separated in two classes: whole seeds (deachenes) and split seeds (achenes). Seeds were placed into semipermeable and impermeable containers and stored for twelve months under environment and cold chamber conditions (10ºC, 45% RH). Physiological and sanitary seed quality (germination, first counting, accelerated aging and seedling emergence in greenhouse) were evaluated at 0, 3, 6, 9 and 12 months of storage. Mechanical harvesting increased split seeds. Whole seeds harvested mechanically had higher vigor than whole seeds harvested manually. Coriander seeds maintain physiological quality up to one year in any storage conditions. However, for uncontrolled storage conditions, seeds may be placed in hermetic containers. Split seeds of coriander show potential to stand establishment.
