Abstract

This study was conducted in the laboratories of the Palm Research Center of the University of Basrah. The study studied the effect of different concentrations of seawater (0, 10, 20, 30, and 40%) and different concentrations of Salicylic acid (0, 50, and 100 mg / L) (MS) with a concentration of 4.6 g / l to add some amino acids and some vitamins and use of NAA at a concentration of 10 mg / L and  2,4.D at a concentration of 20 mg / L. The results of the study showed that increased seawater in the medium increased In the concentration of amino acid proline and phenols and significantly reduced In the total carbohydrate either increased the concentration of salicylic acid has led to a significant increase in total carbohydrates and phenols and significantly reduced in the amino acid proline. As for the effect of seawater on the actual antioxidant enzymes, the results of the present study showed that its increased concentration in the medium resulted in a significant increase in the effectiveness of SOD, CAT, and APX enzymes and significantly reduced the effect of enzymes (PO and GR) salicylic acid increased in the medium to a significant increase in all enzymes studied.

Abstract

Salinity is the major abiotic factor that reduced the plant germination percentage, growth and productivity. However, micronutrients have an important role to reduce the salt stress effectively. This study was conducted to investigate the role of Fe via seed priming of Vigna radiata L. with two concentrations (100ppm & 200ppm) of FeSO4 and grown under various levels (0-50-75-100mM) of NaCl. The results showed that NaCl stress reduced the germination percentage of Vigna radiata but seed priming with FeSO4 improves the germination percentage. The seed priming with 100ppm showed maximum values of germination percentage (96.66±0.23), shoot length (37.84±0.08 cm), shoot fresh weight (26.87±0.067) and dry weight (9.05±0.08), root length (23.27±0.020), fresh weight of root (5.17±0.031), root dry weight (2.48±0.06), Proline (65.30±0.24) were observed. While 200ppm showed significantly maximum values of chlorophyll a& b contents, total soluble protein (0.372±0.18), Phenolic contents (95.57±0.12) and flavonoids (84.26±0.17). Seed priming with FeSO4 has significant effects on the Vigna radiata L. under NaCl stress and improves the germination, growth and biochemical parameters.
