Investigation of pathogens removal from wastewater using a hydroponic system
… The current municipal wastewater treatment systems employ the chlorination process for disinfection and inactivation of pathogenic microorganisms. This process has been associated with life threatening drawbacks, which has necessitated the application of green technology in wastewater …

Effect of bidens pilosa L in sulfate removal from industrial wastewater in a hydroponic system
… In order to remove sulfate from wastewater, two hydroponic systems were constructed, and the first one was cultivated with Bidens pilosa L and the other one was left unplanted (control section). Wastewater collected from Tendele Coal Mine was introduced into both sections and the initial sample …

Measuring the Physiological Effects of Methylobacterium oryzae Foliar Inoculation onto Salt-Stressed Tomatoes grown in a Greenhouse Semi-Hydroponic System
<p>Salinity stress has been shown to improve hydroponic produce quality such as that of tomato but at the trade-off of produce yield. In order to improve demand for hydroponic produce, techniques that improve salinity tolerance could offset declines in yield without altering the improved quality of …

Using Tall Fescue to Remove Nutrients from Renovated Turkey Processing Wastewater
… treatment efficiencies of a greenhouse-based hydroponic system. The wastewater, from a turkey processing plant, was treated in a sand bioreactor system. Reduction of nitrate and phosphorus from wastewater was quantified in the influent and effluent to evaluate the performance of the …

Effects of several abiotic and biotic factors and plant hormones on growth, morophology, and camptothecin accumulation in Camptotheca acuminata seedlings
… were conducted with C. acuminata seedlings in a hydroponic system with commercial media and fluorescent lights and at 22-26 °C to investigate the effects of these five factors on height, weight, leaf number, leaf length, root to shoot ratio (RSR), specific leaf weight (SLW), CPT concentrations …

Understanding the Impact of Plant Nutrition on Plant-Oomycete Interactions
… is an unexplored area. We developed a hydroponic system to precisely control the nutrients applied to plants. We used Arabidopsis thaliana and Nicotiana benthamiana (N. b) as model plants. Hyaloperonospora arabidopsidis as well as two Phytophthora species, Phytophothora capsici (P. cap) …

An open source controlled environment agriculture platform : exploration of root zone temperature effects and thermal management
… was built with air and water temperature control systems. Caesar basil seedlings were grown in the GRObot with a shallow water culture hydroponic system for two-week periods. In the first trial, the root zone temperature (RZT) was allowed to fluctuate with the air temperature resulting in an …

Development of Open-Source Gantry-Plus Robot Systems for Plant Science research
… scarce, however with the availability of such a system, many research tasks can be streamlined. In this project, we demonstrate a prototype of such an open-source, low-cost, heterogeneous robotic system called Mini T-Rex. We combine two over-the-counter robots and leverage the ROS2 framework to …

Root growth potential and bud dormancy of three northern pines with emphasis on eastern white pine
… study examined Root Growth Potential (RGP) in a hydroponic system and Dormancy Release Index (DRI) in one-year-old (1-0) and two-year-old (2-0) eastern white pine (Pinus strobus L.), red pine (Pinus resinosa Ait.), and Scotch pine (Pinus sylvestris L.) seedlings with emphasis on eastern white …

The Impact of Iron Deficiency on Plant-Oomycete Interactions
… threat to global food production and natural ecosystems. Novel modes of oomycete disease control could increase crop yield and reduce pesticide application. Overlaps between the plant response to iron deficiency and pathogens have been documented, but the impact of simultaneous imposition of both …

Green Chimney - Localized Carbon Sequestration in closed Environment
… medium. Since reducing elevated CO2 by using hydroponic system have not been investigated extensively and comprehensively, it is essential to investigate the response of specific plants once they are exposed to very high concentration of CO2. In this research, a new technology -called Green …

Feedback regulation of nitrogenase and response of a hypernodulating soybean mutant to increased photosynthate supply
… plants were grown in growth chambers using a hydroponic system. A wide range of C:N ratios in various plant tissues was generated through a combination of light, CO$\sb2,$ and N levels, using two soybean genotypes differing in C and N acquisition rates and in tolerance of nodulation to …

Conyza bonariensis glyphosate tolerance as affected by origin temperature and growth stage
… was patented as a broad-spectrum, non-selective, systemic herbicide in 1974. In 1996, glyphosate-resistant Lolium rigidum (rigid ryegrass) was reported in Australia. Since then 34 other weeds the world over have evolved resistance to this herbicide. The first case of glyphosate resistance in South …

The role of GABA in plant salinity and hypoxia responses
… seedlings grown in square petri dishes and hydroponic system, respectively, were used to examine the impact of salt on root elongation, biomass and shoot ion content. To examine the response of plants with altered GABA metabolism to hypoxia, plants were grown for up to 4.5 weeks in short day …
