The current study was to assess the influence of a different type storage conditions and preservative seed vigor and temperature storage method in retaining the viability of seeds of Acacia species had been successfully prophesying germination demand in several threat categories and seeds were limited store-controlled conditions due to early damage. Seeds of four A. species were stored at room temperature stored, cold stored, Arial and underground stored for a period of 0, 4, 8, 12, 16, 20 and 24 months. The results revealed that the degree of dormancy variation among the species, they were 81% for A nilotica, 74% for A. seyal, 15% for A. mellifera and 5% for A. senegal. Further, the studies were exhibited germination affected by storage time. Room storage temperature presented significantly declined in germ inability. Even more, the cold, aerial and underground storage conditions indicated effective method for preservation of A. seeds and maintenance of seed viability and storability for 24 months of storage. However, there were very few differences in response to break dormancy treatments before and after 24 months storage. As the storage period advances, A. seyal, A. mellifera and A. senegal there were progressively reduction in hard seed percentage from the beginning of the 4 months of cold, aerial and underground storage. The different responses may be reasonable by the reduction of the seed degradation in breaking dormancy and germination behavior into the room, cold, aerial and underground storage conditions can be utilized how these species might respond to environmental change, and also, used for the formation of artificial seed banks of A. species. Therefore, the aerial seed storage affects germination behavior of small seeded halophytes, further, aerial seed storage may protect seeds from detrimental salinity effects, insects and fungal are the major causes for quantitative and qualitative losses.
