Core-labelling technique (CLT): a novel combination of the ingrowth-core method and tracer technique for deep root study
BackgroundIngrowth-core method is a useful tool to determine fine root growth of standing crops by inserting root-free soil in mesh-bags for certain...

Seasonal patterns of fine root dynamics and their contribution to net primary production in hinoki cypress (Chamaecyparis obtusa) and konara oak (Quercus serrata) forests
Key messageFine root and litterfall are major contributor of NPP and fine root production may reflect forest productivity in a warm-temperate forest...
-
Extreme-duration drought impacts on soil CO2 efflux are regulated by plant species composition
AimsLong-duration drought can alter ecosystem plant species composition with subsequent effects on carbon cycling. We conducted a rainfall...

Fine root phenology differs among subtropical evergreen broadleaved forests with increasing tree diversities
AimsFine root phenology represents ecological strategy of plants in utilizing soil resources and plays an essential role in carbon and nutrient...

How deep can ectomycorrhizas go? A case study on Pisolithus down to 4 meters in a Brazilian eucalypt plantation
Despite the strong ecological importance of ectomycorrhizal (ECM) fungi, their vertical distribution remains poorly understood. To our knowledge, ECM...

Mineral nutrition
Statements that plant growth or the biomass production of a terrestrial ecosystem is nutrient limited are always true, and hence, reflect a truism...

Root phenotypic detection of different vigorous maize seeds based on Progressive Corrosion Joining algorithm of image
BackgroundThe root phenotypes of different vigorous maize seeds vary a lot. Imaging roots of growing maize is a non-invasive, affordable and high...

Root distribution, orientation and root length density modelling in Eucalyptus and evaluation of associated water use efficiency
A mathematical model was used in this study to simulate the root architecture comprising of both structural and geometric components, to reproduce...

Effects of root diameter, branch order, soil depth and season of birth on fine root life span in five temperate tree species
Fine root life span is a key variable influencing the belowground dynamics of forest ecosystems and is known to be associated with a complex suite of...

Effects of Microtopography on Absorptive and Transport Fine Root Biomass, Necromass, Production, Mortality and Decomposition in a Coastal Freshwater Forested Wetland, Southeastern USA
Forested wetlands are an important carbon (C) sink. Fine roots (diameter < 2 mm) dominate belowground C cycling and can be functionally defined into...

Fine-root growth in a forested bog is seasonally dynamic, but shallowly distributed in nutrient-poor peat
Background and aimsFine roots contribute to ecosystem carbon, water, and nutrient fluxes through resource acquisition, respiration, exudation, and...

Soil type more than precipitation determines fine-root abundance in savannas of Kruger National Park, South Africa
AimsOur aim was to examine how soil type and precipitation affect fine-root abundance in savanna ecosystems across Kruger National Park (KNP), South...

Root System Architecture of Salix miyabeana “SX67” and Relationships with Aboveground Biomass Yields
This study focused on relationships between soil properties, root architecture, and aboveground biomass productivity of Salix miyabeana “SX67”. Roots...

Accounting for Carbon Flux to Mycorrhizal Fungi May Resolve Discrepancies in Forest Carbon Budgets
Carbon (C) fluxes among different components of plant growth are important to forest ecosystem C cycling and are strongly influenced by species...

Contrasting phenology of Eucalyptus grandis fine roots in upper and very deep soil layers in Brazil
Background and aimsWhile the role of deep roots in major ecosystem services has been shown for tropical forests, there have been few direct...

Seasonal Patterns of Root Production with Water and Nitrogen Additions Across Three Dryland Ecosystems
Root production is known to contribute at least 50% of total net primary production in dryland ecosystems, yet few studies have addressed seasonal...

A pulse of summer precipitation after the dry season triggers changes in ectomycorrhizal formation, diversity, and community composition in a Mediterranean forest in California, USA
Rapid responses of microbial biomass and community composition following a precipitation event have been reported for soil bacteria and fungi, but...

A novel QTL QTrl.saw-2D.2 associated with the total root length identified by linkage and association analyses in wheat (Triticum aestivum L.)
Main conclusionIn wheat, a QTL QTrl.saw - 2D.2 associated with the total root length was identified, presumably containing genes closely related to...
