Bioprospecting of Beneficial Bacteria Traits Associated With Tomato Root in Greenhouse Environment Reveals That Sampling Sites Impact More Than the Root Compartment

open access: yesFrontiers in Plant Science, 2021
Tomato is subject to several diseases that affect both field- and greenhouse-grown crops. To select cost-effective potential biocontrol agents, we used laboratory throughput screening to identify bacterial strains with versatile characteristics suitable ...

Frequency-sampling design of delay-root-Nyquistfilters

open access: yesElectronics Letters, 1997
The frequency sampling design technique is applied in the design of fractional-delay root-Nyquist filters. Comparisons are made with three alternative design styles, showing that favourable frequency sampling selections easily outperform these contenders with respect to composite impulse response zero-crossing errors and approach the quality provided ...

Minirhizotron measurements can supplement deep soil coring to evaluate root growth of winter wheat when certain pitfalls are avoided

open access: yesPlant Methods
Background Root growth is most commonly determined with the destructive soil core method, which is very labor-intensive and destroys the plants at the sampling spots.

Comparison of tomato root distributions by minirhizotron and destructive sampling [PDF]

open access: yes, 2003
Calibration of minirhizotron data against root length density (RLD) was carried out in a field trial where three drip irrigation depths: surface (R0) and subsurface, 0.20 m (RI) and 0.40 m depth (RII) and two processing tomato cultivars: `Brigade' (CI ...

Bayesian Unit Root Test with Outliers Observations: The Case of Daily Returns of 50 Active in Tehran Stock Exchange Companies [PDF]

open access: yesمدلسازی اقتصادسنجی, 2019
The main drawback of classical ADF and PP tests is the low power of test in small samples and their asymptotic distribution discontinuous. In contrast, many prominent scholars support the Bayesian unit root tests. In the present study, Bayesian unit root

Sampling Distributions of Random Electromagnetic Fields in Mesoscopic or Dynamical Systems

open access: yes, 2009
We derive the sampling probability density function (pdf) of an ideal localized random electromagnetic field, its amplitude and intensity in an electromagnetic environment that is quasi-statically time-varying statistically homogeneous or static ...

Analysing the relationship between ectomycorrhizal infection and forest decline using marginal models [PDF]

open access: yes, 1999
This statistical survey originates from the problem of discovering which relationship exists between root ectomycorrhizal infection and health status of forest plants.

Phytophthora Identification and Sampling in Citrus Nurseries

open access: yesEDIS, 2015
Phytophthora species are important soil-borne, fungus-like pathogens that attack the root systems, trunk, and fruit of citrus trees at any age. The front of this identification sheet includes images of healthy and infested roots and descriptions of leaf

Effects of field inoculation with VAM and bacteria consortia on root growth and nutrients uptake in common wheat [PDF]

open access: yes, 2018
This study investigated the effects of a commercial biofertilizer containing the mycorrhizal fungus Rhizophagus irregularis and the diazotrophic N-fixing bacterium Azotobacter vinelandii on root and shoot growth, yield, and nutrient uptake in common ...
