2021年9月29日 · The fine-root traits (represented by brown arrows) are specific root length (SRL), root diameter (D), root tissue density (RTD) and root nitrogen concentration (N).

Fine root turnover is an essential process controlling the uptake, conservation, and loss of nutrients, water, and carbon between plants and soils. As such, it is at the core of the recent but already well-known and hotly debated root economics space (RES) theory.

A fine root is most commonly defined as a plant root that is two millimeters or less in diameter. [1] Fine roots may function in acquisition of soil resources (eg. nutrients, water) and/or resource transport, making them functionally most analogous to the leaves and twigs in …

2021年2月15日 · We extracted the following fine-root functional traits from each study: root system traits (root biomass and total root length), morphological traits (diameter and SRL), chemical traits (root C, root N, root phosphorus (P), root C : N ratio and root nonstructural carbohydrates), dynamics (root production, root mortality, belowground net primary ...

Check out this list of publications that have used FRED as a go-to resource for all of their root trait data needs! FRED is built on community data and its continued improvement and expansion hinges largely on community interest and engagement. We strongly encourage researchers to directly contribute data. After all…the next version of FRED ...

2023年10月26日 · Fine root decomposition is a physio-biochemical activity that is critical to the global carbon cycle (C) in forest ecosystems. It is crucial to investigate the mechanisms and factors that control fine root decomposition in forest ecosystems to understand their system-level carbon balance.

2017年2月28日 · While fine roots play an important role in ecosystem functioning, fine-root traits are underrepresented in global trait databases. This has hindered efforts to analyze fine-root trait variation and link it with plant function and environmental conditions at a global scale.

2022年1月4日 · Fine roots of plants are wonderful organs. Capable of interweaving thousands of square metres of surface in the soil and able to accumulate nutrients in a proportion of 10 000 to one with respect to the surrounding solution, root behaviour and function have fascinated generations of biologists (Darwin & Darwin, 1880; Epstein, 1973).

Fine root turnover is caused by the production, mortality, and decay of small-diameter roots. Fine root production has been estimated to account for up to 33 percent of global annual NPP (Gill and Jackson 2000), and the lifespan of

2014年12月2日 · Fine roots are essential in plant resource acquisition and play an important role in soil carbon cycling. Nonetheless, root trait variation is still poorly quantified and rarely related to the rest of the plant.
