Humic substances (HSs) are the natural organic polyelectrolytes formed from biochemical weathering of plant and animal remains. Their macromolecular structure chemistry determine their role in biogeochemical processes. In situ spectromicroscopic evidence showed that HS structures (size shape) vary as a function origin (soil versus fluvial), solution chemistry, associated mineralogy. The HSs do not simply form coils acidic or strong electrolyte solutions elongated dilute alkaline solutions....
Abstract The effects of UV‐C (4.1 kJ m −2 ) and heat treatment (45 °C, 3 h in air) either separately or combined on the quality strawberries ( Fragaria × ananassa cv Seascape) at 75 50% surface red ripening stage were assessed, latter being used only firmness test. In addition, development fungal infections was followed vitro germination assays conidia Botrytis cinerea Rhizopus stolonifer performed. Both treatments, decreased hue delayed changes L * parameter. All treatments reduced...
Abstract BACKGROUND: Strawberry is a soft fruit, considered as non‐climacteric, being auxins the main hormones that regulate ripening process. The role of ethylene in strawberry currently unclear and several studies have revision possible this hormone. RESULTS: fruit were harvested at white stage treated with ethephon, an ethylene‐releasing reagent, or 1‐methylcyclopropene (1‐MCP), competitive inhibitor action. effects treatments on quality parameters activity enzymes related to anthocyanin...
The fruit of the strawberry Fragaria×ananassa has traditionally been classified as non-climacteric because its ripening process is not governed by ethylene. However, previous studies have reported timely endogenous production minor amounts ethylene well differential expression genes synthesis, reception, and signalling pathways during development. Mining Fragaria vesca genome allowed for identification two main biosynthetic genes, 1-aminocyclopropane-1-carboxylic acid (ACC) synthase ACC...

Abstract Minimally processed broccoli was treated with UV‐C light (8 kJ m −2 ) and subsequently stored for 21 days at 4 °C. The treatment delayed yellowing chlorophyll degradation during storage. Treated florets displayed lower electrolyte leakage respiratory activity, indicating higher tissue integrity. samples showed phenolic ascorbic acid contents as well antioxidant activity than controls. also had a content of soluble sugars, but no differences in the proteins between control were...
Fully red strawberries (Fragaria × ananassa Duch. cv. Selva) were treated for 1−5 h at temperatures ranging from 39 to 50 °C. After treatments, fruits placed 0 °C overnight and then held 20 3 days. Most of the heat treatments improved strawberry shelf life, with best results obtained fruit heated 42 48 h. Heat prevented fungal development decreased number damaged fruits. These used treat 50−75% analyze effects on firmness, surface color, anthocyanin content, PAL activity, polypeptide...
Broccoli (Brassica oleracea L.) is a rapidly perishable vegetable crop. Several postharvest treatments have been applied in order to delay de-greening. Since light has shown an effect on pigment accumulation during development and darkness known induce senescence, the of continuous periodic exposure low-intensity white at 22 °C senescence broccoli heads was assayed.Exposure constant dose 12 micromol m(-2) s(-1) selected as most suitable treatment employed for subsequent experiments.
