Effect of Salt Stress on Seedlings Growth and Ions Homeostasis of Soybean (Glysin Max) Cultivars

چکیده
This experiment was carried out in Islamic Azad university (Shoushtar Branch) for investigate effect of salt stress on seedling growth of soybean cultivars. The soybean cultivars (Hill, Klark and Williams) obtained from Iran seed and plant institute, Karaj, Iran. The experimental design was 2 factorial, arranged in completely randomized design with 4 replication. First factor was soybean cultivars and second factor was salt stress levels (0, 4, 8, 12 and 16ds/m NaCl solution). These salinity treatments named S0.S1,S2,S3 and S4. Results indicated salt stress led to decrease germination, seedling fresh weight, seedling growth and seedling K percentage in dry matter but increase Mean germination time and seedling Na + percentage. Results showed cultivar Hill K/Na ratio was higher compared Williams and Klark. Results indicated under salt stress seedling growth of cultivar Hill was better compared other soybean cultivars.

Photosynthesis Properties and Ion homeostasis of Different Pistachio Cultivar Seedlings in Response to Salinity Stress
Understanding mechanisms of salt tolerance, physiological responses to salt stress, and screening genotypes for breeding programs are important scientific issues remained to be investigated in pistachio. Therefore, current study was carried out to investigate response of different pistachio cultivars (G1, G2, Kaleghochi and UCB1) to salinity treatments (0.6 as control, 10, 20 dS m-1 using salin...
متن کاملImpact of sea salt stress on growth and some physiological attributes of some soybean (Glycine Max L.) varieties.
The impact of three levels of sea salt (0.0, 8.0, and 16.0 mS/cm2) on six varieties of soybean (Crawford, G21, G22, G35, G82, and G83) was studied. Growth criteria, photosynthetic pigments, soluble sugars, soluble protein, free amino acids, free proline, and protein profile of soybean varieties were investigated under sea salt stress. Results of this study showed a considerable decrease in grow...

In this research, the response of shoot and root of two cultivars of soybean (Glycine max L. cvs Gorgan 3 & Williams) to mild and severe drought was evaluated in pot. Two weeks after of planting, three irrigation treatments including every day (as control), once in three (as mild stress) and five days (as severe stress) were used. The results showed that, stem dry weight, stem and root length, ...

In this experiment soybean seeds were pre-treated with salt tolerant isolate of Trichoderma harzianum to evaluate the different aspects of seedling growth and metabolism in response to different concentrations of NaCl. Trichoderma isolate was more effective in improving dry weight and root volume of seedlings during mild salt stress. Seedlings obtained from bioprimed seeds had significantly hig...

The effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), in the seedlings’ roots or shoots of three winter canola (Brassica napus L.) cultivars, Colvert (tolerant), Symbol (semi tolerant) and Agat (susceptible). Seedlings were treated with 0 (control), 50, 100 and 150 mM NaCl for 24 h in hydropoic c...
