Effect of Root Moisture Content and Diameter on Root Tensile Properties.

PLoS ONE, 2016
The stabilization of slopes by vegetation has been a topical issue for many years. Root mechanical characteristics significantly influence soil reinforcement; therefore it is necessary to research into the indicators of root tensile properties.

Root Penetration Is Associated with Root Diameter and Root Growth Rate in Tropical Forage Grasses

Grasses
Soil compaction impedes root exploration by plants, which limits access to nutrients and water, ultimately compromising survival. The capability of roots to penetrate hard soils is therefore advantageous.

Coupling Root Diameter With Rooting Depth to Reveal the Heterogeneous Assembly of Root-Associated Bacterial Communities in Soybean. [PDF]

Front Microbiol, 2021
Root diameter and rooting depth lead to morphological and architectural heterogeneity of plant roots; however, little is known about their effects on root-associated microbial communities. Bacterial community assembly was explored across 156 samples from three rhizocompartments (the rhizosphere, rhizoplane, and endosphere) for different diameters (0.0 ...

The root economics spectrum: divergence of absorptive root strategies with root diameter [PDF]

Biogeosciences, 2015
Abstract. Plant roots usually vary along a dominant ecological axis, the root economics spectrum (RES), depicting a tradeoff between resource acquisition and conservation. For absorptive roots, which are mainly responsible for resource acquisition, we hypothesized that root strategies as predicted from the RES shift with increasing root diameter.

Increased aortic root diameters in patients with acromegaly [PDF]

European Journal of Endocrinology, 2008
ObjectiveThe clinical manifestations of acromegalic cardiomyopathy include arrhythmias, valvular regurgitation, concentric left ventricular (LV) hypertrophy, and LV systolic and diastolic dysfunction. At present, it is unknown whether acromegaly also affects the aortic root.DesignAortic root diameters were prospectively assessed in 37 acromegalic ...

Deep rooting development and growth in upland rice NERICA induced by subsurface irrigation

Plant Production Science, 2020
Changes in root development and growth in upland rice receiving subsurface irrigation were evaluated using root box experiments. Irrigated water was independently applied every day to depths of 0, 5, 10 and 20 cm from the ground surface, and root ...

Variation in sugar maple root respiration with root diameter and soil depth [PDF]

Tree Physiology, 1998
Root respiration may account for as much as 60% of total soil respiration. Therefore, factors that regulate the metabolic activity of roots and associated microbes are an important component of terrestrial carbon budgets. Root systems are often sampled by diameter and depth classes to enable researchers to process samples in a systematic and timely ...

Changes in anatomy and root cell ultrastructure of soybean genotypes under manganese stress Alterações anatômicas e ultraestruturais em genótipos de soja pela desordem nutricional em manganês

Revista Brasileira de Ciência do Solo, 2009
The deleterious effects of both Mn deficiency and excess on the development of plants have been evaluated with regard to aspects of shoot anatomy, ultrastructure and biochemistry, focusing mainly on the manifestation of visual symptoms. However, there is

Echocardiographic Measurement of Aortic Root Diameter

Japanese Heart Journal, 1976
One hundred and thirty patients with various heart diseases who underwent angiocardiography were studied to assess the clinical usefulness of echocardiographic aortic root diameter. The echocardiographic aortic root diameter was measured from the anterior surface of the anterior wall to the anterior surface of the posterior wall at end-diastole.

On the Diameter of Rice Crown Roots

Japanese Journal of Crop Science, 1978
In rice plants, the diameter of root, thickness of cortex, number of cortical cell layers and width of cortical cells were measured in both mature and apical parts of crown roots. In mature part of roots, it could be proved that the thickness of cortex was in harmony with the diameter of root, but in the case of stele diameter, only slight change was ...
