Soil acidification alters root morphology, increases root biomass but reduces root decomposition in an alpine grassland

Environmental Pollution, 2020
Soil acidification has been expanding in many areas of Asia due to increasing reactive nitrogen (N) inputs and industrial activities. While the detrimental effects of acidification on forests have been extensively studied, less attention has been paid to grasslands, particularly alpine grasslands.

Root biomass of the root-herb layer in coniferous ecosystems of Slovakia

1998
Detailed information was gathered and synthesised about biomass production in the root-herb layer in coniferous ecosystems in Slovakia. Pine forests (Pinus sylvestris, Pinus mugo), mixed deciduous-coniferous forests (Fagus sylvatica, Acer pseudoplatanus, Abies alba, Picea abies), fir forests (Abies alba), and spruce forests (Picea abies) were analysed.

Impact of changes in root biomass on the occurrence of internal browning in radish root

Plant Physiology and Biochemistry
The purpose of this study was to investigate the effects of root biomass during the later stage of growth on fatty acid composition and lipid peroxidation, and to clarify the physiological mechanisms by which these differences affect internal browning (IB) development in radish roots.

Aerenchyma in sugarcane roots: a toolbox for tailoring biomass for bioenergy

Journal of Experimental Botany
Abstract Sugarcane is a major feedstock for first-generation ethanol production, but the efficient conversion of its lignocellulosic residues into second-generation biofuels remains limited by the resilience of its cell wall. Here, we suggest sugarcane root aerenchyma as a relevant biological model to study in vivo mechanisms of cell ...

Maize Root Biomass and Net Rhizodeposited Carbon

Soil Science Society of America Journal, 2006
Assessment of net primary productivity of maize ( Zea mays L )‐based agroecosystems is dependent on both above and belowground dry matter production that is ultimately returned to the soil as residue and decaying roots.

Measurement of proliferation and biomass of fungal hyphae and roots

Geoderma, 1993
Abstract New questions are being asked about the functional role of soil fungi, plant roots and their interactions. Existing methods to study the species composition and biomass of soil fungi and roots are outlined and the limitations of the data derived from them are discussed.

ESTIMATING ROOT LENGTH DENSITY AND BIOMASS IN ASPARAGUS

Acta Horticulturae, 2002
Soil type, crop management practices, annual plant growth patterns and seasonal changes in the soil environment all influence asparagus roots. This study describes the changes that occur in root growth over time in two contrasting soils and crop management systems.

Biomass of Fine Roots in a White Spruce Plantation

Canadian Journal of Forest Research, 1972
Biomass of fine roots (≤3 mm diameter) in a white spruce (Piceaglauca (Moench) Voss) plantation in Maine was estimated at 696 ± 224 g/m2 or 3 kg per tree. Data consisted of 10 samples collected in midsummer from the top 45 cm of an imperfectly drained, silt loam, alluvial soil.

Root biomass distribution in an energy willow plantation [PDF]

Agricultural Engineering, 2015
Celem pracy było określenie rozmieszczenia biomasy korzeni wierzby energetycznej,które jest istotne ze względu na opracowanie, w ramach projektu badawczego, konstrukcji maszyny do rekultywacji pól po jej uprawie. Zakresem pracy objęto badania przeprowadzane na 30 karpach wierzby energetycznej, pochodzących z plantacji założonej w 2003 roku na Wydziale ...

Estimating coarse root biomass of balsam fir

Canadian Journal of Forest Research, 2007
Root systems of 31 balsam fir ( Abies balsamea (L.) Mill.) trees were excavated at five sites in central New Brunswick. Sites ranged from 10 to >80 years in stand age; most had been thinned at least once, and densities ranged from 750 to 44 000 trees·ha–1.
