Combined effects of bisphenol A and cadmium on growth and nitrate assimilation of soybean seedling roots
Bisphenol A (BPA) and cadmium (Cd) pollution exist simultaneously in many regions. However, little information is available regarding the combined effects of BPA and Cd pollution on plants. Plant roots are in direct contact with the soil, which is an important compartment of BPA and Cd. Here, the effects of combined BPA and Cd pollution on soybean seedling roots were evaluated in pot ...

QTL analysis of root architecture traits and low Phosphorus tolerance in an Andean bean population
Tolerance to low P soils is a desirable trait in common bean (Phaseolus vulgaris L.) cultivars grown in acid-weathered soils. Genetic variability in response to P-deficient soils exists in the Andean gene pool. G19833, a low P–tolerant indeterminate Andean landrace, has been evaluated for quantitative trait loci (QTL) and tolerance to low P in combination with Mesoamerican parents. Our goal was ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil
Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the bacterial exo-polysaccharides (EPS), however, such a role of the EPS-producing bacteria in the saline environments has rarely been investigated. Pot ...

Outposts: CI-600 In-Situ Root Imager at the Arctic Station
Icebergs dot the bay along the coast of Disko Island, home of the University of Copenhagen’s Arctic Station. Here researchers study environmental issues impacting the Polar Regions, including physical geography, botany, and zoological research. Dr. Marie Frost Arndal, Faculty of Science, University of Copenhagen, is heading a research project studying root dynamics in the Arctic. Her ...

Amelioration of physical strength in waste foundry green sands for reuse as a soil amendment
To avoid increasing costs of landfill disposal, it has become increasingly important for U.S. foundries to identify beneficial reuses for the 8 to 12 million tons of waste foundry sand (WFS) generated annually. A major drawback to the reuse of some WFSs as a soil amendment is their high soil strength, under dry conditions, where root growth may be limited. Fifteen WFSs were analyzed for strength ...

Copper induced root growth inhibition of Allium cepa var. Agrogarum L. involves disturbances in cell division and DNA damage
Copper (Cu) is considered an indispensable microelement for plants. However, excessive Cu is toxic and disturbs several processes in the plant. The present study addressed the effects of ionic Cu (2.0 µM and 8.0 µM) on mitosis, microtubule cytoskeleton and DNA in root tip cells of Allium cepa var. agrogarum L., in order to better understand Cu toxicity on plant root systems. Results indicated ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

Bacterial communities associated with the rhizosphere of transgenic Bt 176 maize (Zea mays) and its non transgenic counterpart
The effect of transgenic Bt 176 maize on the rhizosphere bacterial community has been studied with a polyphasic approach by comparing the rhizosphere of Bt maize cultivated in greenhouse with that of its non transgenic counterpart grown in the same conditions. In the two plants the bacterial counts of the copiotrophic, oligotrophic and sporeforming bacteria, and the community level catabolic ...

How the University of Florida uses 200 root tube installations with the CI-602 root imager
The University of Florida, Institute of Food and Agricultural Sciences (UF/IFAS), Plant Root Biology Laboratory led by Dr. Lorenzo Rossi is located at the Indian River Research and Education Center (UF/IFAS IRREC) in Fort Pierce, Florida. Situated in the heart of the premiere grapefruit growing region of the world, the lab primarily uses the CI-602 root imager to study grapefruit root growth and ...

Determining aluminum tolerance and critical soil pH for winter canola production for acidic soils in temperate regions
A growing interest in winter canola (Brassica napus L.) across the southern Great Plains has brought about many issues regarding production. One of the issues to be addressed is winter canola's tolerance of Al when grown on acid soils. The objectives of this study were to determine the maximum Al concentration and minimum pH for canola production in a temperate region with a known acid soil ...

An alternate wetting and moderate soil drying regime improves root and shoot growth in rice
A major challenge in rice (Oryza sativa L.) production is to achieve the dual goal of increasing food production and saving water. This study aimed to investigate if alternate wetting and drying regimes could improve root and shoot growth and consequently increase grain yield and water use efficiency (WUE). Two rice varieties were field-grown at Yangzhou, China in 2005 and 2006. Three irrigation ...

Ozone for Vertical Farming
Ozone in vertical farming is an excellent organic fungicide and biocide. In addition to its high efficiency and the advantages of not leaving chemical residues on the leaves. When ozone is dissolved in water favors root growth and increases dissolved oxygen in plants. About 90% of the water used worldwide is for agriculture. Ozone helps reduce the amount of water and helps inactivate viruses ...

An Instrumented Rhizotron to Investigate the Root Growth In Wheat - Case Study
There has been much recent interest in modifying root system properties to overcome the effects of soil abiotic stress on crop growth and yield (Lynch 2007; Ghanem et al. 2011). Plant root systems are usually exposed to heterogeneous environmental conditions due to vertical differences in soil moisture and strength. Strong subsurface layers of soil can confine root systems to shallower soil ...

Evaluation of air pollution phytotoxicity downwind of a phosphate fertilizer factory in India
The effects of air pollution on plants downwind of a fertilizer factory at Udaipur, India, were studied using three woody perennials. Seedlings of these species including a shrub (Carissa carandas L.), a leguminous avenue tree (Cassia fistula L.) and a fruit tree (Psidium guajava L.) were grown in earthen pots at different study sites receiving varying levels of air pollution input. Changes in ...

Germination and early plant development of ten plant species exposed to TiO2 and CeO2 nanoparticles
Ten agronomic plant species were exposed to different concentrations of nano titanium dioxide (nTiO2) or nano cerium oxide (nCeO2) (0, 250 µg/mL, 500 µg/mL and 1000 µg/mL) to examine potential effects on germination and early seedling development. We modified a standard test protocol developed for soluble chemicals (OPPTS 850.4200) to determine if such an approach might be useful for screening ...

Creeping bentgrass putting green turf responses to two summer irrigation practices: Rooting and soil temperature
Light and frequent (LF) and deep and infrequent (DI) irrigation are two common practices for golf course managers. Few studies have compared the effects of these two opposing irrigation practices on summer root performance in creeping bentgrass (Agrostis stolonifera L.). The objectives of this field study were to quantify summer root development and longevity in response to LF vs. DI irrigation ...
