Seed aging adversely affects germination, vigour, and biochemical efficiency, resuling in reducing the seed performance and crop growth. Present study addressed the effects of SA priming at varying concentrations (0.10, 0.25, 0.50, 0.75, and 1.00 mM) on the physiological and biochemical attributes of aged (10, 11, 12, 13 and 14 month old) tomato seeds. Results revealed that 0.50 mM SA priming significantly enhanced seed vigour index I from 19.6 % to 41.3% over control in 10 month and 14 month old seed, respectively. Likewise, protein was increase 27 % dehydrogenase (29%) and α-amylase (19%) over the control at 14th month old seed EC was reduced to 28% over control. In contrast, higher SA concentrations (0.75 and 1.00 mM) negatively impacted seedling growth, highlighting a threshold beyond which SA becomes inhibitory. The lowest root length was recorded in 1.00 mM SA primed seeds. The controlled treatment showed higher root length than 1.00 mM SA treated seeds. The seed germination (%) of 10-month-old seed was varied between 78.66 and 89% which were significantly different (P=0.05). This study demonstrates that the optimal SA concentration is crucial for effective seed priming, providing new insights into the physiological and biochemical pathways activated in aged tomato seeds. These findings contribute to the unexplored field of seed aging and establish 0.50 mM SA as an effective concentration for improving seed quality.
