  • Choosing the Right Light for Young Plants

    Horticulture lighting research has been conducted on young plants (germination, seedlings, plugs and cuttings) for many years. Michigan State University published a series of articles in Greenhouse Grower (see references below) on bedding plant seedlings. In their research, Drs. Wollaeger and Runkle experimented with different LED wavelengths and compared them to fluorescent light on seedling ...

  • New and old soybean cultivar responses to plant density and intercepted light

    Genetic gain for new soybean [Glycine max (L.) Merr.] cultivars is substantial, and research suggests this is partially explained by greater tolerance to increased plant densities. We conducted an experiment to determine if greater tolerance to increased plant density and more efficient use of cumulative intercepted photosynthetically active radiation (CIPAR) partially explained the yield ...

  • Breaking light bulb myths

    I have to agree with the Tea Party; the US government should not choose the light bulbs I use in my home.  And fortunately, it does not. Yet that’s the spin being pushed by those who want to roll back federal lighting performance standards. An odd mythology is  ...

  • Shedding Light on Land Tenure in Africa

    Land and natural resources lie at the heart of social, political, and economic life in much of rural Africa. They represent fundamental assets—primary sources of livelihood, nutrition, income, wealth, and employment for African communities—and are a basis for security, status, social identity, and political relations. For many rural people, land and resources such as water, trees, and ...

  • Cold light shines on Paris climate pledges

    The world’s leading economies are heading in the right direction on tackling climate change, but some still have a long way to go to make their undertakings politically credible, according to a UK research centre. With the Paris Agreement barely two months old, the world now moves from talk to action − or at least that’s the ...

  • Shedding light on NO homeostasis: Light as a key regulator of glutathione and nitric oxide metabolisms during seedling deetiolation

    Abstract Despite the significant impacts of light on nitric oxide (NO) levels in plants, the mechanism underlying the influence of this environmental factor on NO metabolism remains poorly understood. A critical mechanism controlling NO levels in plant cells relies on the S-nitrosylation of glutathione (GSH), giving rise to S-nitrosoglutathione (GSNO), which can be either stored or ...

  • Light and moisture competition effects on biomass of red clover underseeded to winter wheat

    Red clover (Trifolium pratense L.) use as an underseeded cover crop in winter cereals has declined due to inability of growers to consistently establish uniform stands. The objective of this study was to assess the effect of light and soil moisture competition on underseeded red clover establishment and end of season dry matter production. Field trials were conducted at multiple locations in 2005 ...

  • Simple models for carbon assimilation by plants

    The detailed processes in photosynthesis are complicated and hard to model. In many cases, however, it’s possible to simplify the model by focusing on one or more of the limitations to assimilation. Carbon Assimilation Simplified: Light and WaterIn simplest terms, carbon assimilation involves the chemical transformation of carbon dioxide and water to carbohydrate and oxygen within the leaves of ...

  • New documentary shines a light on solutions to global species loss

    A paper published last week in the journal Science Advances claims the sixth major mass extinction is already underway ­— and this time humans are to blame. “We can confidently conclude that modern extinction rates are exceptionally high, that they are increasing, and that they suggest a mass ...

    Grow Journal Of Cajun Belle Peppers Under LED Grow Lights This cajun belle pepper grow journal uses our VF150 150 watt led grow light. The grow space is 2×3 ft although this single pepper plant takes up about 18×30 inches. It was started from transplant on 5/28/13. The ...


  • Corn morphology, mass, and grain yield as affected by early-season red: far-red light environments

    The spatial arrangement among plants affects both vegetative and reproductive meristem development. More axillary meristems develop at lower plant densities, which are associated with relatively high red:far-red light ratios (R:FRs; 645:735 nm). However, little is known about the effect of R:FR on corn (Zea mays L.) productivity. We conducted field research to determine the effect of early-season ...

  • Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes

    The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects of different fluctuating light regimes (from 24 to 100% transmissivity) on leaf physiology, morphology, anatomy, and structure of orchardgrass (Dactylis glomerata L.) in a ...

  • Response of yield heterosis to increasing plant density in maize

    Genetic yield improvement in maize (Zea mays L.) has been associated with heterosis and increased tolerance to high plant densities, but the physiological processes underlying heterosis for tolerance to plant density stress have not been identified. The objective of this study was to quantify the response of heterosis for grain yield to increasing plant density, and to examine the processes ...

  • Grana-localized Proteins, RIQ1 and RIQ2, Affect the Dynamics of Light-harvesting Complex II and Grana Stacking in Arabidopsis

    Grana are thylakoid structures that are observed in land plants and in which photosystem II (PSII) and light-harvesting complex II proteins (LHCIIs) accumulates. We isolated two Arabidopsis mutants, reduced induction of non-photochemical quenching (riq1 and riq2), in which stacking of grana was enhanced. The curvature thylakoid 1a (curt1a) mutant was previously shown to lack the grana structure. ...
