A comparison between water uptake and root length density in winter wheat: effects of root density and rhizosphere properties [PDF]

, 2020
© 2020, The Author(s). Background and aims: We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots ...

Characterizing Root Morphological Traits in 65 Genotypes of Foxtail Millet (Setaria italica L.) from Four Different Ecological Regions in China

Agronomy, 2022
As an indispensable grain crop, foxtail millet (Setaria italica L.) is becoming a functional food in China because of its abundant nutrients. However, low rainfall and uneven precipitation limit its growth and production, especially in northwest China ...

Study Root System Structure and Characterstics in Wheat (Triticum aestivum L.) Cultivars Influenced by Applications of Sources of Fertilizer under Dryland Farming [PDF]

بوم شناسی کشاورزی
IntroductionAmong the nutrients used by the plant for the growth of nitrogen due to its participation in the structure of proteins, amino acids, coenzymes and nucleic acids are the main factors involved in plant growth and fertility. In recent decades, a

Different Responses in Root Water Uptake of Summer Maize to Planting Density and Nitrogen Fertilization [PDF]

, 2022
Modifying farming practices combined with breeding has the potential to improve water and nutrient use efficiency by regulating root growth, but achieving this goal requires phenotyping the roots, including their architecture and ability to take up water

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]

, 2009
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

Pitfalls in Root Trait Calculations: How Ignoring Diameter Heterogeneity Can Lead to Overestimation of Functional Traits

Frontiers in Plant Science, 2017
Specific root length (SRL) and root tissue density (RTD) are ecologically functional traits which are calculated from root length or volume and root dry weight. Both can be converted into each other using the root diameter assuming roots are cylindrical.

Effect of humic acid as a photosensitizer combined with low-energy laser on orthodontic tooth movement in rats

Journal of Dental Sciences, 2022
Background/purpose: Humic acid (HA) could promote light conversion reaction, and lasers accelerate orthodontic tooth movement. We investigated the effect of HA, as a photosensitizer, combined with low-energy laser on orthodontic tooth movement in rats ...

Intraspecific variation in root and leaf traits and leaf-root trait linkages in eight aspen demes (<i>Populus tremula</i> and <i>P. tremuloides</i>)

Frontiers in Plant Science, 2013
Leaf and fine root morphology and physiology have been found to vary considerably among tree species, but not much is known about intraspecific variation in root traits and their relatedness to leaf traits.
