Root traits are multidimensional: specific root length is independent from root tissue density and the plant economic spectrum [PDF]

Journal of Ecology, 2016
Summary Root, stem and leaf traits are thought to be functionally coordinated to maximize the efficiency of acquiring and using limited resources. However, evidence is mixed for consistent whole‐plant trait coordination among woody plants, and we lack a clear understanding of the adaptive value of root traits along soil resource gradients.

Interspecific interactions alter root length density, root diameter and specific root length in jujube/wheat agroforestry systems

Agroforestry Systems, 2014
A field study was conducted at Hetian, southern Xinjiang, northwest China, to investigate root morphology as affected by interspecific interactions between jujube (Ziziphus jujuba Mill.) and wheat (Triticum aestivum L.). The treatments comprised (1) sole wheat, (2) 3-, 5- and 7-year-old sole jujube trees, and (3) intercropping of wheat/3-, 5- and 7 ...

Seasonal dynamics of fine root biomass, root length density, specific root length, and soil resource availability in a Larix gmelinii plantation

Frontiers of Biology in China, 2006
Fine root turnover is a major pathway for carbon and nutrient cycling in terrestrial ecosystems and is most likely sensitive to many global change factors. Despite the importance of fine root turnover in plant C allocation and nutrient cycling dynamics and the tremendous research efforts in the past, our understanding of it remains limited.

Responses of root length/leaf area ratio and specific root length of an understory herb, Pteridophyllum racemosum, to increases in irradiance

Plant and Soil, 2003
The understory evergreen perennial Pteridophyllum racemosum Sieb. et Zucc. (Papaveraceae) has the ability to increase root mass per unit transpiring leaf area (RMA) if irradiance increases gradually over several years. In this study, we examined how P.

Relationships between specific root length and respiration rate of fine roots across stands and seasons in Chamaecyparis obtusa

Plant and Soil, 2017
Fine root respiration (R r ) is closely linked with fine root morphology, especially with specific root length (SRL), in short-term measurements in some tree species. However, whether these relationships are also valid across different stands and seasons is not yet known.

Effects of NaCl salinity on 15N-nitrate fluxes and specific root length in the halophyte Plantago maritima L.

Plant and Soil, 2003
The effect of salinity on nitrate influx, efflux, nitrate net uptake rate and net nitrogen translocation to the shoot was assessed in a N-15 steady state labelling experiment in the halophyte Plantago maritima L. raised for 14 days on solution supplied with 50, 100 and 200 mol m(-3) sodium chloride or without sodium chloride.

A significant increase in rhizosheath carboxylates and greater specific root length in response to terminal drought is associated with greater relative phosphorus acquisition in chickpea

Plant and Soil, 2020
We investigated the effects of water stress under low phosphorus (P) supply on P-acquisition by chickpea, and identified a genotype with faster relative growth and P-acquisition rates. We grew four genotypes in pots filled with a sand and soil mixture with a low P availability in a glasshouse.

[Distribution patterns of Fraxinus mandshurica root biomass, specific root length and root length density].

Ying yong sheng tai xue bao = The journal of applied ecology, 2006
Employing soil core method, an investigation in Maoershan Experiment Station was made on the root biomass, specific root length (SRL), and root length density (RLD) of Fraxinus mandshurica plantation (17 yr) within a growth season in stand level. The results showed that the total root biomass was 1,637 g x m(-2), in which, living biomass accounted for ...

[Effects of fertilization on fine root diameter, root length and specific root length in Larix kaempferi plantation].

Ying yong sheng tai xue bao = The journal of applied ecology, 2007
With 16 years old Larix kaempfersoil plantation in the mountainous area of eastern Liaoning Province as test object, this paper studied the effects of fertilization on the fine root diameter, root length, and specific root length (SRL) of the first to fifth order roots. The results showed that with ascending root orders, the mean fine root diameter and

Variation in specific root length among 23 wheat genotypes affects leaf δ13C and yield

Agriculture, Ecosystems & Environment, 2017
Abstract Identifying root traits that are associated with efficient nutrient and water utilization is crucial for improving plant functioning and productivity. In the case of wheat genotypes, such root traits could be used by plant breeders to improve grain yield and quality.
