Installation and imaging of thousands of minirhizotrons to phenotype root systems of field-grown plants
BackgroundRoots are vital to plant performance because they acquire resources from the soil and provide anchorage. However, it remains difficult to...

Deep roots: implications for nitrogen uptake and drought tolerance among winter wheat cultivars
Background and aimsDeep roots are needed to allow uptake of nitrogen (N) and water available in the deeper soil layers, to help tolerate increasingly...
-
A multispectral camera system for automated minirhizotron image analysis
AimsRoots are vital organs for plants, but the assessment of root traits is difficult, particularly in deep soil layers under natural field...
-
Recent trends in root phenomics of plant systems with available methods- discrepancies and consonances
The phenoty** of plant roots is a challenging task and poses a major lacuna in plant root research. Roots rhizospheric zone is affected by several...
-
Non-invasive phenoty** for water and nitrogen uptake by deep roots explored using machine learning
Background and aimsRoot distribution over the soil profile is important for crop resource uptake. Using machine learning (ML), this study...

Shifts in root dynamics along a hillslope in a mixed, mesic temperate forest
AimsComplex topography, a common feature of forested areas, generates unique environmental gradients that may shape root dynamics in unexpected ways....
-
Adaptive minirhizotron for pepper roots observation and its installation based on root system architecture traits
BackgroundRoot is the principal part of plants to absorb water and nutrient, anchor the plant and affect yield and quality. Non-destructive detection...

Deep root uptake of leachable nitrogen in two soil types is reduced by high availability of soil nitrogen in fodder radish grown as catch crop
AimsPlant available soil nitrogen (N) may affect deep root growth and soil N depletion by catch crops. We investigated the influence of topsoil N...
