“…The findings are in agreement with those obtained by Jabeen and Ahmad (2012) in sunflower. In particular, SOD constitutes the end product of peroxidation of membrane lipids and is the first line of defense against ROS (Hussain et al, 2016). Our result indicated that the lowest MDA content (9.13 µmol/g FW) and the highest activity (85.46 µmol min -1 mg -1 FW) of SOD were obtained from cv.…”

This study was conducted to evaluate the alterations of some morphological and biochemical parameters of sunflower cultivars ('08-TR-003', 'TR-3080' and 'TARSAN-1018') under salt stress. For this aim, the seedling of sunflower cultivars was irrigated with tap water as a control, and with salinized water with 50, 150 and 250 mM NaCl for 30 days under controlled conditions. Salinity caused an apparent reduction in morphological parameters (plant height, leaf area, fresh weight, dry matter and water content) in all cultivars. Salt stress significantly (P<0.01) reduced the activity of glutathione reductase (GR) and ascorbate peroxidase (APX) activities in all sunflower cultivars expect for superoxide dismutase (SOD) activity. According to our results, SOD seems to play a key role in the antioxidative process in salt treated sunflower plants. Proline and MDA contents were significantly (P<0.05) increased under salt stress in all cultivars. Among the cultivars, 'TR-3080' had greater values in terms of morphological (plant height, leaf area, fresh weight, water content) and biochemical (GR, APX and SOD (secondly) activities and proline contents) parameters. In the light of these findings, cv. 'TR-3080' seems to be less affected by salt stress.

“…Salinity stress is one of the most serious abiotic stress factors limiting crop productivity, and it is a menace for the cultivation of plants across the globe and causes drastic changes in plant growth and development (Roy et al, 2014;Hussain et al, 2016). NaClspecific damage is associated with the accumulation of Na + in leaf tissues and results in necrosis of older leaves, starting at the tips and margins and working back through the leaf.…”

To understand the functions of exogenous 24-Epibrassinolide (EBR) in enhancing the salt tolerance of wheat (T. aestivum L.) seedlings to salt stress, a hydroponic experiment was performed to investigate the effects of EBR on chlorophylls, root activity, H + -ATPase, malondialdehyde (MDA), electrolyte leakage, free proline, soluble protein, reactive oxygen species (ROS), antioxidant enzymes and minerals content in wheat plants subjected to non-stress conditions or salt stress (120 mM NaCl) with foliar application of EBR (1, 10 and 100 nM). Results showed that spray of low concentrations EBR (1 and 10 nM) under non-stress conditions could promote wheat plant growth. 120 mM NaCl induced osmotic stress, oxidative stress and imbalance in mineral nutrients absorption. However, EBR enhanced the ability of resistance to osmotic stress by increasing free proline and soluble protein content, and enhanced the ability of resistance to oxidative stress by increasing antioxidant enzymes activities. As a result of increase of chlorophyll content, root activity and H + -ATPase activity, the inhibition of K, Ca, Mg, Fe and Zn uptake was ameliorated and consequently, decline in plant growth induced by NaCl stress was alleviated. Based on these results, we conclude that EBR had a positive role in regulating wheat growth and development under salt stress, and spray of 10 nM EBR had the most significant alleviating effect against NaCl toxicity.

“…Under lower rainfall and limited input farming system, Safflower planting is a good choice. This plant have a great oil yield potential and able to grow under high temperatures, drought, and salinity (Hussain et al, 2015). It has also found for industrial applications such as biofuel (Dajue and Mundel, 1996).…”

This study was carried out as split split plots in a randomized complete block design with three replications at Research Field of Agriculture Faculty, during 2014-2015 in Iran. In this study, the main factor was two safflower cultivars including: Sina and Faraman and subplot were foliar application of fulvic acid in 2 stages as: stem elongation and flowering and also sub sub plot were 3 different fulvic acid concentrations including as: 0: control (distilled water), 0.5 and 1 kg * ha -1 . The results showed that the characters including: numbers of seed in head, 1,000 seed weight, seed yield, harvest index and oil percent were affected significantly by safflower cultivars, and also head weight were affected in different growth stages. Also the results of fulvic acid were showed significant different about head numbers, numbers of seed in head, biological yield, harvest index and oil percent. In this study the maximum seed yield and oil percent were achieved by Faraman cultivar in comparison with Sina, as it produced 14.33 and 19.5 percent more seed yield and oil percent in arrangement. Foliar application in stem elongation stage obtained 6.02 percent more seed yield but in flowering stage, fulvic acid spraying were achieved 35.5 percent more oil percent. Finally the results showed the positive effects of foliar application of fulvic acid in 1 kg * ha -1 , as it produced 85.67 percent more oil percent in comparison with control.
