Rapid microwave processing of winter cereals for histology allows identification of separate zones of freezing injury in the crown
In histological studies, microwave processing of tissue considerably shortens the time required to prepare samples for observation under light and electron microscopy. However, plant tissues from different species and different regions of the plant respond differently to microwave processing, making it impossible to use a single protocol for all plant tissue. The crown of winter cereals such as ...

Modified Atmosphere Packaging Gets a New QA Tool for Fresh-Cut Produce
Measuring only CO2 and O2 in Modified Atmosphere Packaging for produce leaves out an important key marker of produce freshness: Ethylene (C2H4). C2H4 production is a natural part of the plant life cycle, a complex hormone that varies not only between species, but from crop to crop of the same species. C2H4 has been called the plant “death hormone”, because as part of the natural ...

Organically complexed iron enhances bioavailability of antimony to maize (Zea mays) seedlings in organic soils
Antimony (Sb) is a metalloid belonging to group 15 of the periodic table. Chemical similarities between arsenic (As) and Sb produce concerns about potential health effects of Sb and enrichment in the environment. Antimony is found in oxic environments predominately as an oxyanionic species, antimonite (Sb[OH]6–). As a result of its net negative charge, Sb[OH]6– was not initially predicted to ...

The fate and transport of Phosphorus in turfgrass ecosystems
Phosphorus losses from turfgrass areas are perceived to contribute to water quality problems, yet a comprehensive review of P fate in turfgrass ecosystems is lacking. According to available data in the literature, phosphorus fertilizer inputs (2–10 kg ha–1) slightly exceed the estimated outputs of phosphorus in clippings (0.4–7.5 kg ha–1). Sediment losses from turf areas are negligible, generally ...

Effects of co-application of biosolids and water treatment residuals on corn growth and bioavailable Phosphorus and Aluminum in Alkaline Soils in Egypt
The co-application of biosolids and water treatment residuals (WTRs) has been previously trialed to reduce excessive bioavailable P in the soil treated with biosolids. However, uncertainty still exists regarding the environmental consequences of the co-application of biosolids and WTRs, especially in alkaline soils in Egypt or the Middle East region. A greenhouse pot study was conducted with ...

Desiccation-tolerant plants in dry environments
The majority of terrestrial plants are unable to survive in very dry environments. However, a small group of plants, called ‘resurrection’ plants, are extremely desiccation-tolerant and are capable of losing more than 90% of thecellular water in vegetative tissues. Resurrection plants can remain dried in an anabiotic state for several years and, upon rehydration, are able to resume normal growth ...
