A comparison of root diameter and protein content of hair to serum protein, urinary nitrogen, and diet in preschool children
… investigation was to evaluate the use of hair root diameter and protein/root as a practical and reliable field method for assessment of protein nutritional status. Subjects were thirty-five Caucasian preschool children from rural low-income families. Hair root diameter and protein/root were …

Phenotypic Plasticity within the Native Perennial Grass, Poa secunda (Sandberg bluegrass), an Important Component of the Western United States Sagebrush Grassland Vegetation
… The ability to respond to competition through root plasticity may be an important trait for survival of native plants in invaded systems. I investigated the following questions about Poa secunda, a common native perennial grass in sagebrush ecosystems: 1) Can P. secunda respond plastically to …

Corn root growth and distribution as influenced by soil physical properties
Mechanisms of root growth under variable field conditions were investigated by observing corn ( Zea mays L.) root growth and distribution in the field and by observing the influence of soil physical stresses on corn seedling root growth in controlled environments. The field soil was Groseclose silt …

The influence of fin height and wall conductivity on integral-fin tubes during steam condensation
… conditions. The tubes tested had an inner diameter of 12.7mm, a root diameter of 13.88mm, and fin heights ranging from 0.5mm to 1.5mm, in 0.25mm increments. The outside heat transfer coefficient was determined first by finding the overall heat transfer coefficient, Uo, then by using the …

The effects of relative planting dates of legumes on productivity of cassava - legume intercrop
… of primary and secondary branches and stem diameter were measured tor cassava trom 3 months after planting until 10 months after planting. For legumes plant height were taken tor growth starting trom 8 weeks after planting until physiological maturity. Yield and yield components tor cassava …

Understanding plant water relations and root biomechanics for hydro-mechanical reinforcement of slopes
… via both mechanical reinforcement (through root anchorage) and hydrologic reinforcement (through transpiration-induced soil matric suction). However, relatively little is known about the effectiveness of different plant species in stabilising soil slopes via the two reinforcing mechanisms, …

Produção de mandioca (Manihot esculenta Cranz) sob dois sistemas de plantio
… the production of aboveground biomass and root production of two varieties of cassava tame popularly known as "Cedinha" and "Pão do Chile", which are grown in two planting systems: Leirão and Cova. The trial was conducted under field conditions in the property "Site Cumbe" located in the …

Recombinant Chromosome Substitution Lines as a Source of Genetic Variation for Drought Stress Tolerance in Barley
… experiment revealed genotypic variation for root traits such as seminal root elongation rate, root diameter and gravitropism that could potentially determine differences in soil water and nutrient acquisition from early stages of development in restrictive environments.<br/><br/>This study …

Linking Plant and Soil Microbial Diversity via Plant Functional Trait Ecology
… While plant functional traits such as biomass, root diameter, and root tissue nutrients explained variation in bacterial communities, PFTs did not relate to differences in fungal communities. However, specific bacterial and fungal taxa showed strong associations with particular PFTs. Chapter 3 …

Fine root dynamics in the Boreal Forest of northern Saskatchewan, Canada
The study of fine roots (FR) (roots < 2 mm in diameter) in the boreal forests has become a focus of many forest researchers in the past decade in an effort to better understand belowground processes and improve current carbon (C) models to better predict possible C sinks and sources. The objectives …

Coarse Root Biomass and Architecture: Applications of Ground Penetrating Radar
… radar (GPR) to identify and quantify coarse roots was tested in a mixed-oak forest in Southeastern Virginia using experimental pits and locally excavated root segments. GPR was found to be highly dependent on low soil moisture levels as it is unable to differentiate root structures if they …

Characterization of tomato root-endophytic fungi and analysis of their effects on plant development, on fruit yield and quality and on interaction with the pathogen Verticillium dahliae
… endophytes are able to colonize internally roots without causing visible disease symptoms establishing neutral or mutualistic associations with plants. These fungi known as non-clavicipitaceous endophytes have a broad host range of monocot and eudicot plants and are highly diverse. Some of …
