Under ideal cool, dry, airtight storage conditions, the normal shelf life of Salicornia europaea seeds is 12 months after harvest. Within this period, Salicornia europaea seeds keep high vitality and stable germination performance, which is the best time for sowing.
Once Salicornia europaea seeds are stored for more than one year, their internal nutrients gradually degrade, embryo activity weakens, and the germination rate starts to drop slowly. After 2 years of storage, most Salicornia europaea seeds lose strong germination ability. Even if some seeds can sprout, seedlings are weak and grow slowly, not suitable for large-scale field planting.
Storage environment is the key factor changing the shelf life of Salicornia europaea seeds. If Salicornia europaea seeds are kept in hot, humid places without sealing, their shelf life may be reduced to only 3 to 6 months. High humidity causes mildew, while high temperature accelerates seed aging, quickly destroying the embryo inside Salicornia europaea seeds.
For seed suppliers, it is necessary to mark harvest date and expiry date on the package of Salicornia europaea seeds. Before purchase or sowing, growers should check the production time of Salicornia europaea seeds and do a small germination test for aged batches.
To extend the usable time of Salicornia europaea seeds, follow standard storage methods: fully dry seeds, use sealed moisture-proof packaging, and store in dark and low-temperature surroundings. Avoid frequent opening of seed containers, which brings in warm moist air and shortens the shelf life of Salicornia europaea seeds.
In summary, Salicornia europaea seeds are best used within 12 months post harvest. Good storage can retain seed activity, while bad conditions drastically shorten the shelf life of Salicornia europaea seeds. Always prioritize fresh harvested Salicornia europaea seeds to get reliable germination results.
