Abstract: Accelerated ageing test is an efficient vigour test to measure the seed vigour and predict seed storability and their longevity. The laboratory experiment was conducted at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore during 2017. This study was conducted on groundnut CO 7 pods and the pods were subjected to the accelerated ageing at 40 ± 1 oC and 100% relative humidity for various time intervals (1, 2, 3, 4, 5, 6, 7, 8, 9 & 10 days). The samples were drawn daily from accelerated ageing condition and physical, physiological and biochemical attributes of seeds were evaluated. The result of the study revealed that speed of germination, first count (%), germination (%), root length (cm), shoot length (cm), dry matter production (g seedlings -10), vigour index, field emergence (%), viability (%) and dehydrogenase enzyme activity (OD value) decreased and moisture content (%) and electrical conductivity (µS cm-1 g-1) increased with increase of accelerated ageing periods. In the present study, initially the pods showed higher germination (84 per cent) and reached Indian Minimum Seed Certification Standards (IMSCS) of 70 per cent germination 4 days after accelerated ageing.
