Seed priming is a physiological seed enhancement technique. Hydropriming method can advance germination under unfavorable conditions. The ability of hydropriming to mitigate ageing damage was evaluated in coriander. Seeds were subjected to accelerated ageing for 48 h at 42C and thereafter hydroprimed at 20C for 5, 10 and 15 h, respectively. Hydropriming significantly improved final germination percentage, germination rate, seedling length, vigour index, soluble sugars, total soluble proteins, catalase, superoxide dismutase and ascorbate peroxidase activities of aged seeds. Mean germination time, electrical conductivity and malondialdehyde content of primed seeds decreased in comparison to non-primed seeds. Hydropriming for 5, 10 and 15 h improved final germination percentage to 24.4, 40 and 95.5%, germination rate by 8.6, 29.3 and 41.4% and vigour index by 25.7, 70.7 and 166.8% as compared to non-primed seed, respectively. These results suggest that increased antioxidant enzyme activities affect germination performance of aged coriander seeds due to hydropriming for 15 h. In this study, aged coriander seeds were primed with distilled water in three durations. Some parameters such as germination percentage and rate, mean germination time, seedling length, vigour index, electrical conductivity, soluble sugars, total soluble proteins, malondialdehyde contents and antioxidant enzymes activities were evaluated for seed quality. Hydropriming improved the germination parameters of aged seeds. In comparison to non-primed ones, primed seeds were associated with a decrease in electrical conductivity, malondialdehyde values and an improvement of catalase, ascorbate peroxidase and superoxide dismutase activities and soluble sugars as well as, protein content. Therefore, hydropriming for 15 h could significantly mitigate the growth inhibition of aged coriander seed. It also protects morphological and physiological parameters from oxidative damage.

Key words: Ageing, catalase, coriander, hydropriming.
