Home | Fine-Root Ecology Database
Welcome to FRED! Those of us focused on measuring belowground processes have dusted off our data, pooled them together into one harmonized database, and freely shared these hard-won observations. Our hope is that they will be used by the broader community of root and rhizosphere ecologists to tackle some of the biggest questions in belowground ...
Fine-root traits in the global spectrum of plant form and function
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 - Wikipedia
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 …
细根 - 维基百科，自由的百科全书
细根 （英語： fine root），是指 植物根系 中周转较快的那部分根，作为媒介传输土壤中的营养元素及水分至植物中 [1]。 细根周转（turnover）的过程中会释放大量的 碳 进入土壤中，形成大量的土壤有机质。 土壤有机质受到环境的影响（气温、水分、肥料）会迅速释放大量的CO 2，从而受到了广泛学者的关注。 北方森林（boreal forest）只占陆地土壤面积的15% 却拥有约33%的净初级生产力（NPP），对环境的变化最为敏感 [2]。 细根通常< 2mm，寿命远远小于粗根，从几个 …
Linking fine root lifespan to root chemical and morphological
Belowground, fine root traits are organized around several synthetic axes of variation that define plant economics strategies (the “root economics space”, RES) (7, 8).First, a trade-off between high metabolism (represented by root N concentration; RN) and high investment in structural compounds (represented by root tissue density; RTD) is …
Fine‐root functional trait responses to experimental warming: a …
2021年2月15日 · Tackling this question is crucial to better understanding terrestrial responses to climate change as fine-root traits drive many ecosystem processes. We carried out a detailed synthesis of fine-root trait responses to experimental warming by performing a meta-analysis of 964 paired observations from 177 publications.
Dissecting how fine roots function - Valverde‐Barrantes - 2022
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 - an overview | ScienceDirect Topics
It is the small absorbing roots of 0.1–1mm in diameter, which are called fine roots, that are responsible for most of the acquisition from the soil of resources such as water and nutrients. From: The Science of Grapevines (Third Edition), 2020. About this page. Chapters and Articles.
Redefining fine roots improves understanding of below-ground ...
2015年3月10日 · Fine roots acquire essential soil resources and mediate biogeochemical cycling in terrestrial ecosystems. Estimates of carbon and nutrient allocation to build and maintain these structures remain uncertain because of the challenges of consistently measuring and interpreting fine-root systems.
Frontiers | Editorial: Root functional traits: From fine root to ...
2023年2月14日 · Plant roots perform multiple essential functions defining plant ecological success and ecosystem functioning. For instance, roots are vital for plant nutrient and water uptake, thus regulating net primary production and nutrient cycling (Freschet et al., 2021). In the last decade, the adoption and advancement of a functional trait approach has ...
