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.

Genetic variation and host-parasite specificity of Striga resistance and tolerance in rice: the need for predictive breeding [PDF]
, 2017 The parasitic weeds Striga asiatica and Striga hermonthica cause devastating yield losses to upland rice in Africa. Little is known about genetic variation in host resistance and tolerance across rice genotypes, in relation to virulence differences ...

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 ...

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.

A novel Brassica–rhizotron system to unravel the dynamic changes in root system architecture of oilseed rape under phosphorus deficiency [PDF]
, 2016 Background and Aims: An important adaptation of plants to phosphorus (P) deficiency is to alter root system architecture (RSA) to increase P acquisition from the soil, but soil-based observations of RSA are technically challenging, especially in mature ...

Sugarcane root system depth in three different countries [PDF]
, 2010 THE SUGARCANE root system depth is crucial as it determines the potential depth of soil available for water and nutrient uptake by the crop. It was reported in an early publication that these roots could grow quite deep (6 m), but otherwise very little ...

Observing the invisible: X‐ray CT for plant–microbe interactions
New Phytologist, EarlyView.Utility of X‐ray computed tomography (X‐ray CT) for visualising belowground plant interactions between multiple spatial scales and focal planes. Summary Plant–microbe interactions are inherently spatial, yet the physical structure of the soil and rhizosphere is rarely treated as a mechanistic variable in experimental design.
