“…The gradual decrease in % seed germination with increasing concentration of NaCl is evident from the present results where both percentage germination and the rate of germination declined with salinity. Several chemicals and salts are used to accomplish better germination and accomplish healthy seedlings under stress (Ashraf et al, 2008). Our results are in line with the findings of Rahman et al, (2000), in which germination was directly related to the amount of water absorbed and delay in germination due to the salt concentration of the medium.…”

Salt stress is one of the most severe environmental factors that reduces and limits growth and development of plants. Abiotic stresses such as heavy metals, salinity, drought, temperature, UVradiation, ozone causes drastic yield reduction in most of the crops. Especially salt stress affects around 20 % of the world ̕ s cultivated areas. This study was conducted in order to evaluate the effect of NaCl on germination and seedling growth of Zea mays L. Seeds of Zea mays were germinated in glass Petri-dishes of 100 × 15 mm diameter lined with blotting paper. Ten seeds were placed in each petri-dish. Petridishes were irrigated with 25, 50, 75, 100, 125, 150, 175 and 200 mM concentrations of NaCl. A control was moistened with ten milliliters of distilled water. The germination percentage, water absorption of the seeds, water uptake percentage and the growth parameters were observed. The results obtained showed that the inhibition of the germination percentage, germination rate, water uptake, growth and biomass accumulation of the seedlings were observed to decrease with increasing NaCl concentrations. At the highest level of stress both plumule and radical decreased significantly. The salt stress decreased seed germination, biomass and growth of maize seedlings due to ion toxicity, decrease osmotic potential and oxidative stress.

“…The salinity reduced the shoot dry weight up to 44.33 per cent compared to absolute control. This observation was supported and reported that salinity decreases growth parameters such as fresh and dry weights of plants [21]. In this present study, jasmonic acid increases the shoot dry weight up to 32.76 per cent [Fig-2].…”

“…Sodium ion could be a toxic factor that results in reduced germination because it causes impaired water uptake, secretion of hormones and modifies the activity of enzyme such as malate dehydrogenase and glucose 6-phosphate dehydrogenase [20]. Pretreatment of seeds with different type of plant growth regulators is much effective in alleviating stress effects of salinity on the plants at different stages especially at early stage and it has been shown to improve seed germination under salt stress [21]. In this present investigation, jasmonic acid restores the salinity stress and increases the germination percentage up to 33.08 per cent followed by gibberellic acid (31.53%) compared to control [ Table-1].…”

“…Ghana et al (2003) reported that seed priming has limited practical worth for enhancing emergence and yield of winter wheat planted deep into summer fallow. Pre-treatment of seeds with different type of hormones and plant growth regulators is much effective in alleviating stress effects of salinity on the plants at different stages especially at early stage and it has been shown to improve crop germination as reported earlier under salt stress (Ashraf & Foolad, 2005;Ashraf et al, 2008). The results of the present study are in agreement with observations of Chauhan et al (2009) who reported that seeds treated with GA 3 showed significant difference with control indicated that the germination percentage decreases when the concentration increased, which shows that higher concentration inhibit germination and the longest radicle length was observed under GA 3 50 ppm.…”

In order to evaluate the effect of different seed priming techniques on germination and early growth of two wheat cultivars (Cross Alborz and Sardari) tow experiments carried out at the Razi University Laboratory of Physiology, Faculty of Agriculture and Natural Resources, Kermanshah, Iran. This study was in two separate experiments. The experiments were factorial arranged in a completely randomized design with four replications. The first factor was seed primed for 12, 18, 24 and 30hours, the second was four concentrations of gibberellic acid (50, 100, 150and 200 ppm), PEG-6000 (-0.3 MPa) and the third was two wheat cultivars. Seeds were primed for 12, 18, 24 and 30 hours at temperature 25°C in different solutions. Results showed that for hormonal priming, maximum shoot and root length, shoot and root dry weight and germination rate were observed at GA 50 ppm and 24 h treatmeant in Cross-Alborz and Sardari cultivars. For osmmopriming maximum shoot and root length, shoot and root dry weight and germination rate were abserved at 12 h treatment.
