the role of priming on seed reserve utilization and germination of mountain rye (secale montanum) seeds under salinity stress
low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...
متن کاملEffect of Priming on Germination and Enzyme Activity of Achillea vermicularis Seeds after Naturally and Accelerated Aging
Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...
متن کاملThe effect of salicylic acid and gibberellin on enzyme activity and germination characteristics of wheat seeds under salinity stress conditions
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 salicyl...
متن کاملEffect of Salicylic Acid on Antioxidant Enzyms of Milk Thistle (Silybum marianum) Accelerated Aging Seed
Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. Experiment was performed in a factorial based on Complete Randomized Design (CRD). Treatments were Salicylic acid concentrations (0, 500, 1000, 1500 and 2000 ppm) and accelerated aging for (0, 48, 96 and 144 hours under 45 °C and 95% humidity) with three replications. Our ...
متن کاملEffects of seed germination with gibberellin on safflower germination under salinity stress
Abstract Salinity is one of the most important factors limiting plant growth and production around the world. Gibberellic acid is known as a strong growth stimulator, effective on seed germination and breaking of seed dormancy in various plant species. In order to study the response of Safflower,Sofeh cultivar, to salinity stress, a factorial experiment was conducted based on a randomized...
