Effects of Planting Method on Root Growth and Nitrogen Uptake of Rice

open access: yesGuan'gai paishui xuebao, 2023
【Objective】 Water and nutrient uptake by plants is modulated by their root architecture. This paper investigates the impact of planting method on root distribution of rice and the associated nitrogen uptake and grain yield.

On the distribution on the roots of polynomials [PDF]

open access: yesAnnales de l'Institut Fourier, 1996
Using classical results on conjugate functions, we give very short proofs of theorems of Erdös–Turán and Blatt concerning the angular distribution of the roots of polynomials. Then we study some examples.

Variability of Root System Size and Distribution among Coffea canephora Genotypes

open access: yesAgronomy, 2022
This work aimed to evaluate the variability in the distribution of the root system among genotypes of C. canephora cv. Conilon and indicate management strategies for a more efficient mineral fertilization. Root distribution was evaluated in six genotypes.

Characterization of Root System Architecture Traits in Diverse Soybean Genotypes Using a Semi-Hydroponic System

open access: yesPlants, 2021
Phenotypic variation and correlations among root traits form the basis for selecting and breeding soybean varieties with efficient access to water and nutrients and better adaptation to abiotic stresses. Therefore, it is important to develop a simple and

A sonic root detector for revealing tree coarse root distribution. [PDF]

open access: yesSci Rep, 2020
AbstractThis study assesses the reliability of a non-destructive method for determining the in situ distribution of tree coarse roots within a scaled distance 6-fold the DBH by comparing the results with the actual 3D root architecture revealed by invasive methods. The root architecture of 22-year-old olive trees was determined non-destructively with a

Location of Drip Irrigation Tapes Affects Root Redistribution and Yield of Mature Jujube

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Flooding irrigation is commonly used to water jujube in Xinjiang. It is not only an inefficient use of the scarce water resources and increases evaporation and leakage, but could also result in soil compaction and secondary soil salinization.

Probability Distribution on Full Rooted Trees [PDF]

open access: yesEntropy, 2022
The recursive and hierarchical structure of full rooted trees is applicable to statistical models in various fields, such as data compression, image processing, and machine learning. In most of these cases, the full rooted tree is not a random variable; as such, model selection to avoid overfitting is problematic. One method to solve this problem is to

Sensitivity of Surface Fluxes in the ECMWF Land Surface Model to the Remotely Sensed Leaf Area Index and Root Distribution: Evaluation with Tower Flux Data

open access: yesAtmosphere, 2020
The surface-atmosphere turbulent exchanges couple the water, energy and carbon budgets in the Earth system. The biosphere plays an important role in the evaporation process, and vegetation related parameters such as the leaf area index (LAI), vertical ...

Effects of root morphology on stress distribution at the root apex [PDF]

open access: yesThe European Journal of Orthodontics, 2007
It is thought that the stress concentration at the root apex caused by orthodontic force induces root resorption. The purpose of this study was to investigate stress distribution at the root in cases of deviated root shapes using finite element models (FEMs).
