The effect of salicylic acid and gibberellin on enzyme activity and germination characteristics of wheat seeds under salinity stress conditions

چکیده
ABSTRACT: Seed priming was used in wheat seeds to increase germination characteristics and tolerance on stress exposure. Wheat seeds were treated with salicylic acid and gibberellin. After 8 days our results showed that, seed priming treatments significantly (p≤ 0.01) affected germination percentage, normality seedling percentage, germination index and seedling length. Seed priming with salicylic acid and gibberellin increased germination characteristics as the compared to the unprimed. Also, priming increased catalase and ascorbate peroxidase as compared to the unprimed seeds. Therefore, the highest germination characteristics and enzyme activity were attained from priming with salicylic acid and gibberellin.

DOR: 98.1000/2383-1251.1398.6.159.11.1.1578.1575 Extended Abstract Introduction: In order to take more advantage of the spring growing season, the mechanisms of germination of spring plants are of great importance at temperatures lower than the optimum temperature. Since one of the ways to reduce damage due to low temperature is enhancing the seedling antioxidant system, in this study the...
