  • Extreme Makeover: Photosynthesis Edition

    Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis

    Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...

  • Recovery of photosynthesis and growth rate in green, blue–green, and diatom algae after exposure to atrazine

    We evaluated the recovery of photosynthesis and growth rate in green (Pseudokirchneriella subcapitata), blue‐green (Anabaena flos‐aquae), and diatom (Navicula pelliculosa) algae after pulsed exposure to atrazine. Subsequent to a grow‐up period of 24 to 72 h to establish requisite cell density for adequate signal strength to measure photosystem II (PSII) quantum yield, algae were exposed to a ...

  • Simulating gross primary productivity of humid-temperate pastures

    Although most pasture growth models simulate many above- and belowground components of the plant community, calibration and validation are usually based only on periodic measurements of aboveground forage yield. This research used daily measurements of gross primary productivity (GPP) to validate the photosynthesis subroutine of the Integrated Farm System Model (IFSM). The model was calibrated ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

  • Yield and water use response of cuphea to irrigation in the Northern Corn belt

    Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

  • SOYPOD: a model of fruit set in soybean

    The soybean [Glycine max (L.) Merr.] plant matches its reproductive potential to environmental conditions by adjusting the number of fruits and seeds that it produces. This adjustment is an important, but not well understood, part of the yield production process. Developing a model of fruit set will contribute greatly to a better understanding of the determination of fruit number and yield. The ...

  • Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae

    phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

  • Algae Photo Bioreactors (APB`s)

    ALGAE PHOTO-BIOREACTORS (APB’s) Absorption of CO2 and NOx from industrial exhaust gases and conversion of algal feedstock, as a discipline of ecological engineering. Algae, live in a wide range of aquatic environments and are a natural component of most aquatic ecosystems being found in both fresh, brackish and marine waters. They range in size from large macrophytic kelps to microscopic ...

  • Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review

    Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...
