Improving the thiobarbituric acid-reactive-substances assay for estimating lipid peroxidation in plant tissues containing anthocyanin and other interfering compounds
Abstract. The occurrence of malondialdehyde (MDA), a secondary end product of the oxidation of polyunsaturated fatty acids, is considered a useful index of general lipid peroxidation. A common methodExpand
Seaweed Extracts as Biostimulants of Plant Growth and Development
A comprehensive review of the effect of various seaweed species and seaweed products on plant growth and development with an emphasis on the use of this renewable bioresource in sustainable agricultural systems is provided. Expand
Using a modified ferrous oxidation-xylenol orange (FOX) assay for detection of lipid hydroperoxides in plant tissue.
Compared with the iodometric assay, the FOX method consistently generated less variable LOOH values, and the presence of authentic linoleic acid-OOHs in spiked avocado and spinach samples was identified with liquid chromatography-mass spectrometry techniques, which validated corresponding FOX assay results.

Antioxidant enzyme responses to chilling stress in differentially sensitive inbred maize lines
Changes in levels of sugar and starch indicated a more rapid disruption of carbohydrate utilization in comparison to photosynthetic rates in the chilling-sensitive line under short-term chilling shocks and suggested a greater degree of acclimation in the tolerant lines over longer periods of chilling. Expand
The effects of ethylene, depressed oxygen and elevated carbon dioxide on antioxidant profiles of senescing spinach leaves.
Declines in levels of ASPX, CAT, and ascorbate over the 35 d storage period suggests that regulation of H2O2 levels plays an important role in both the dynamics and severity of post-harvest senescence of spinach. Expand
Oxidative Stress: Importance for Postharvest Quality
As fresh fruits and vegetables experience many types of stress during processing, storage, and/or transport, an increasing amount of research is being generated on how oxidative stress is associated with postharvest quality. Expand

Anthocyanin and Anthocyanoplast Content of Cruciferous Seedlings Subjected to Mineral Nutrient Deficiencies.
Summary Seedlings of red varieties of cabbage, cauliflower, kohl rabi, radish, and canola were grown hydroponically with complete nutrient, or with nutrient lacking nitrogen. (-N), phosphorus. (-P),Expand
Commercial extract of the brown seaweed Ascophyllum nodosum enhances phenolic antioxidant content of spinach (Spinacia oleracea L.) which protects Caenorhabditis elegans against oxidative and thermal
The results suggest that ANE stimulate flavonoid synthesis in spinach leaf thus enhancing its nutritional quality and exerts beneficial effects in C. elegans against oxidative stress. Expand
A Commercial Extract of Brown Macroalga (Ascophyllum nodosum) Affects Yield and the Nutritional Quality of Spinach In Vitro
The effects of extracts of the brown marine alga (Ascophyllum nodosum, ANE) on growth and biochemical and molecular changes in spinach were studied and the transcript abundance of genes that affect sucrose and glycine betaine metabolism increased. Expand
