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.

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 ...

High-throughput monitoring of root diameter reveals the temporal dynamics of root decomposition

Annals of Botany
Abstract Background and Aims Increasing C storage in cultivated soils requires a better understanding of C dynamics, particularly at depth, where root litter decomposition dynamics is expected to be slower than in ploughed layers ...

A new method to optimize root order classification based on the diameter interval of fine root [PDF]

Scientific Reports, 2018
AbstractPlant roots are a highly heterogeneous and hierarchical system. Although the root-order method is superior to the root diameter method for revealing differences in the morphology and physiology of fine roots, its complex partitioning limits its application. Whether root order can be determined by partitioning the main root based on its diameter

【Short Report】A Quick Method to Estimate Root Length in Each Diameter Class Using Freeware ImageJ

Plant Production Science, 2013
Digital images for determining root traits have been analyzed using WinRHIZO, commercial software. A freeware ImageJ has been developed for the analysis but whether root lengths assigned to root diameter classes obtained by this method correspond to ...

Root diameter controls the accumulation of humic substances in decomposing root litter

Geoderma, 2019
Abstract The humification of plant litter is a crucial step for the buildup of soil organic matter in terrestrial ecosystems. Yet, how environmental change and substrate quality affect root humification still remains poorly understood. A two-year litterbag experiment was conducted to assess the root mass remaining and accumulation of humic substances

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 ...

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
