A novel<i>Brassica</i>–rhizotron system to unravel the dynamic changes in root system architecture of oilseed rape under phosphorus deficiency

Abstract

The Brassica-rhizotron system is an effective method for soil-based root phenotyping across an entire growth cycle. Given that root senescence is likely to occur earlier under low P conditions, crop P deficiency is likely to affect late water and nitrogen uptake, which is critical for efficient resource use and optimal crop yields.
