Mapping the Centimeter-Scale Spatial Variability of PAHs and Microbial Populations in the Rhizosphere of Two Plants. [PDF]
PLoS ONE, 2015 Rhizoremediation uses root development and exudation to favor microbial activity. Thus it can enhance polycyclic aromatic hydrocarbon (PAH) biodegradation in contaminated soils.

Root foraging and avoidance in hyperaccumulator and excluder plants: a rhizotron experiment [PDF]
Plant and Soil, 2020 AbstractAimsMetal hyperaccumulation is a rare phenomenon described for an increasing number of plant taxa. In this study we investigated the root growth responses of the well-known nickel, zinc, cadmium hyperaccumulatorNoccaea caerulescensand of the metal tolerant (non-accumulator)Stellaria media, in order to observe root foraging vs avoidance ...

Root architecture development in stony soils
Vadose Zone Journal, 2021 Soils with high stone content represent a challenge to root development, as each stone is an obstacle to root growth. A high stone content also affects soil properties such as temperature or water content, which in turn affects root growth.

A GIS-based method for the analysis of digital rhizotron images
Plant Root, 2011 Quantification of belowground plant response via rhizotron root image analysis is difficult and time-consuming, yet a plant's root response is of great interest to many researchers. Here, we present an automated, time efficient method for examining digital rhizotron images. A total of 285 digital images (218 mm by 300 mm) were collected using a flatbed

In-Field Observation of Root Growth and Nitrogen Uptake Efficiency of Winter Oilseed Rape
Agronomy, 2020 Field trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage.

Measuring the Root Length of Peanuts Grown in Rhizotrons Using Computer Vision
Anais do XVII Workshop de Visão Computacional (WVC 2021), 2021 Peanut is one of the most grown leguminous crops in the world, but it can suffer during water deficit periods. In this paper, a new method to help monitoring root growth for laboratory experiments with this plant is proposed. By using a new combination of smoothing, thresholding, morphological filtering and skeletonization, our method has achieved a ...
