“…Similar results were found in rice (Uchida et al, 2002) and in wheat (Wahid et al, 2007) both revealed that at lower levels of H 2 O 2 increases the growth and physiological phenomena by preventing oxidative damage and enhanced the capacity to withstand in high salinity conditions. According to, Azevedo Neto et al, (2005) in maize suggested that H 2 O 2 induced an increase in salt tolerance during subsequent exposure to salt stress by the incorporation of hydroponics solution.…”

“…Moreover, supplement of NaCl or Na 2 CO 3 increased the leakage of UV metabolites from leaves. Wahid et al [36] reported that UV-absorbing metabolites increased by salinity. Lipids are major components in membrane, which has main role in plant cell resistance in proportional to salt stress.…”

Soil salinity and sodicity (alkalinity) are serious land degradation issues worldwide that are predicted to increase in the future. The objective of the present study is to distinguish the effects of NaCl and Na 2 CO 3 salinity in two concentrations on the growth, lipoxygenase (LOX) activity, membrane integrity, total lipids, yield parameters and fatty acids (FAs) composition of seeds of sunflower cultivar Sakha 53. Plant growth, LOX activity and malondialdehyde (MDA) content were reduced by salts stresses. On the contrary, salinity and alkalinity stress induced stimulatory effects on membrane permeability, leakage of UV-metabolites from leaves and total lipids of sunflower shoots and roots. Crop yield (plant height, head diameter, seed index and number of seeds for each head) that is known as a hallmark of plant stress was decreased by increasing concentrations of NaCl and Na 2 CO 3 in the growth media. Fatty acid methyl esters (FAME) composition of salt-stressed sunflower seeds varied with different levels of NaCl and Na 2 CO 3 .

“…1; Tables 1and 2) show that treatment with H 2 O 2 as an exogenous source of ROS signiWcantly promotes seed germination in several warm-season C 4 -grasses such as switchgrass, big bluestem and indiangrass. Treating seeds with H 2 O 2 has been shown to promote germination in several other species, including zinnia (Zinnia elegans L.) (Ogawa and Iwabuchi 2001), rice (Oryza sativa L.) (Naredo et al 1998), wheat (Triticum aesitvum L.) (Wahid et al 2007) and barley (H. vulgare L.) (Wang et al 1998). What has not been explored in warm-season grasses is the relationship between H 2 O 2 , NO and ABA during seed germination.…”

For non-dormant switchgrass seeds exhibiting diVerent levels of germination, treatment with H 2 O 2 resulted in rapid germination (<3 days) of all germinable seeds as compared to seeds placed on water. Exposure to 20 mM H 2 O 2 elicited simultaneous growth of the root and shoot system, resulting in more uniform seedling development. Seeds of big bluestem (Andropogon gerardii Vitman) and indiangrass [Sorghastrum nutans (L.) Nash] also responded positively to H 2 O 2 treatment, indicating the universality of the eVect of H 2 O 2 on seed germination in warm-season prairie grasses. For switchgrass seeds, abscisic acid (ABA) and the NADPH-oxidase inhibitor, diphenyleneiodonium (DPI) at 20 M retarded germination (radicle emergence), stunted root growth and partially inhibited NADPH-oxidase activity in seeds. H 2 O 2 reversed the inhibitory eVects of DPI and ABA on germination and coleoptile elongation, but did not overcome DPI inhibition of root elongation. Treatment with H 2 O 2 appeared to enhance endogenous production of nitric oxide, and a scavenger of nitric oxide abolished the peroxide-responsive stimulation of switchgrass seed germination. The activities and levels of several proteins changed earlier in seeds imbibed on H 2 O 2 as compared to seeds maintained on water or on ABA. These data demonstrate that seed germination of warm-season grasses is signiWcantly responsive to oxidative conditions and highlights the complex interplay between seed redox status, ABA, ROS and NO in this system.
