“…Results are the means of three independents assays; bars correspond to Ϯ standard error. Gidrol et al (1989) and Lehner et al (2007) did not find any increase in this compound during the accelerated aging of sunflower or wheat seeds. On the contrary, Goel et al (2003) or Kibinza et al (2006), for example, demonstrated that MDA accumulated during seed aging.…”

“…In the seeds from the Marchouche variety, accelerated aging induced a 9.8% decrease in the proportion of TAG accompanied by a 6.5% increase in the proportions of FFA (Figure 3). No significant variation was Gidrol et al (1989) and Corbineau et al (2002) obtained with sunflower seeds. Unsaturated fatty acid and phosphatidylcholine contents were particularly low.…”

Effects of accelerated aging upon the lipid composition of seeds from two soft wheat varieties from Morocco.The lipid composition of the seeds from two soft wheat varieties (Triticum aestivum, cv. Marchouche and Mahdia) were analyzed before and after accelerated aging. Eight days of accelerated aging resulted in a total inhibition of seed germinability as well as a decrease in their total and especially unsaturated fatty acid contents. Oleic and linoleic acid contents decreased particularly in the phosphatidylcholine of the seeds from both varieties. The proportion of polar lipids also decreased after aging as compared to neutral lipids: a 5.8% and 7.2% decrease in polar lipids was e observed in Mahdia and Marchouche cultivars, respectively. In the neutral lipids of the seeds from the Marchouche variety, the percentage of free fatty acids increased whereas the triacylglycerols decreased. After aging, the fatty acid compositions of all lipid classes were modified in the same manner as total fatty acid compositions. Among polar lipids, phospholipid proportions were particularly small, especially the phosphatidylcholine percentages with an 18.1% and 19.1% decrease in Mahdia and Marchouche varieties, respectively. In contrast, MGDG percentages increased, especially in the seeds from the Marchouche variety. A 15.5% increase was noticed when compared with seeds which were not aged. At the same time, the DGDG percentage showed a 16.6% decrease after accelerated aging of the seeds from the Marchouche variety. From these results we concluded that the lipid content decrease observed in seeds after accelerated aging could be linked to a loss in the germination and vigor of wheat seeds.

“…The per cent increase over control was 17 and 34%, respectively. Gidrol (1989) reported that the decreased activity of peroxidase and catalase was due to accumulation of H 2 O 2, as seeds neutralized free radicals and this accumulation of hydrogen peroxide itself was detrimental to seeds. Depletion of antioxidant enzyme activities was also observed during seed ageing in cotton (Goel et al, 2003).…”

Changes occurring in seed during aging are very significant for determining seed quality, i.e. seed longevity. An experiment was conducted in Department of Seed Science and Technology, TNAU, Coimbatore to standardize suitable seed dry dressing treatments, using near nano size botanicals that can alleviate the deleterious effect of accelerated ageing and to improve the enzyme activities of soybean aged seeds. Five days aged seeds were treated with 1 h ball milled fenugreek seed powder, leaf powders of ashwagandha, tea and noni @ 2 g kg -1 with 60 min. shaking and evaluated for enzyme activities and field emergence (naturally and artificially aged seeds). Among the treatments seeds treated with fenugreek seed powder has the highest dehydrogenase activity (OD 10 min -1 ), protein (%), oil content (%), catalase activity, peroxidase activity (OD 10 min -1 ) (µg H 2 O 2 mg -1 min -1 ) with minimum values of electrical conductivity (dSm -1 ), free fatty acid (%), lipid peroxidation (OD value), lipoxygenase activity (g mol s -1 mg -1 ). Field emergence (%) was also higher in fenugreek seed powder treated seeds (2 g kg -1 with 60 min).

“…those involved in cellular respiration are susceptible to oxidative modifications (Møller 2001). It is thought that damage of mitochondrial membranes increases their permeability and leakage of lipid peroxides to cytoplasm (Gidrol et al 1989). It is suggested that these compounds may participate in signal transduction between mitochondria and other organelles and nucleus.…”

Relatively little is known about the direct influence of acid rain (AR) on pro-and antioxidative changes in plant cells. Intercompartmental differences between cytosol and mitochondria have not been studied before. Aboveground parts of plants were treated with different pH variants of AR and oxidative damages (lipid peroxidation) as well as antioxidative enzyme activities (superoxide dismutase, SOD; ascorbate peroxidase, APx; glutathione peroxidase, GSH-Px) in the cytosolic and mitochondrial fractions were examined. The character of changes in antioxidative enzyme activities and of oxidative damages was closely connected with the cell compartment as well as with pH and time after treatment. The activity of both APx and GSH-Px increased more intensively in cytosol. Contrastingly, strong induction of lipid peroxide formation was observed in the mitochondrial fraction. In both cell compartments SOD activity did not change significantly. The results suggest that cucumber mitochondria are more susceptible to oxidative damage caused by AR than cytosol. Antioxidative defence of cytosol appeared to provide sufficient protection against the oxidative stress imposed by AR.
