Albizia lebbeck commonly called as Vagai or Siris, is a nitrogen fixing, semideciduous tree species, whose leaves and twigs are excellent fodder for camels and other cattle. It is also an excellent source for fuel, charcoal, jaggery mould and gum. Generally, seeds deteriorate, during prolonged storage, but the rate of deterioration varies greatly among the species and provenances. Keeping these in mind, an investigation involving eight different seed sources of A. lebbeck seed collected from four different agro-climatic zones of Tamil Nadu, to evaluate the storage potential of this seed was conducted. After initial evaluation, the seeds at 8% moisture content were packed according to source in plastic containers and stored under ambient conditions. The seed samples were evaluated every three months for seed germinability and vigour. Results, after twenty-one months of storage, revealed that Coimbatore and Aliyar sources of the Western Zone stored better based on higher germination and seedling vigour as compared to other seed sources
