Acacia nilotica is an important multi-purpose tree widely used for fuelwood, fodder, timber, tannin and gum. The climate of India greatly accelerate ageing phenomenon at ambient storage environment causing deterioration and loss of viability. Keeping this in mind, an investigation involving eleven different seed sources of A. nilotica seeds, collected from four different agroclimatic zones of Tamil Nadu were evaluated to determine the storage potential of the seeds. After the initial evaluation, the seeds at 8% moisture content were packed according to seed source in plastic containers and stored under ambient conditions. The samples were evaluated every three months for enzyme activity, seed germinability and vigour. The results after twenty-one months of storage indicated that Erods and Aliyar sources of the Western Zone had higher enzyme activity (amylase, catalase and dehydrogenase), which in turn had higher germination and seedling vigour when compared to other seed sources
