چکیده
|
Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. an experiment was performed in a factorial based on completely randomized design (crd). treatments were salicylic acid concentrations (0, 500, 1000, 1500 and 2000 mg. l-1) and accelerated aging for (0, 48, 96 and 144 hours under 45 °c and 95% humidity) with three replications. our results showed that salicylic acid dramatically enhanced seed germination, seedling vigor and primary seedling growth. catalase, polyphenol oxidase and peroxidase activity were increased by seed priming. reduction in germination parameters were observed by increase in accelerated aging durations. the highest antioxidant activity, germination percentage and daily germination rate and seed vigour were observed at primed seeds with 1000 mg. l-1 salycilic acid on non-aged seeds. salicylic acid treatment with a concentration of 1000 mg. l-1had the greatest impact on healing harmful effects aging.
