Oilseed Rape Cultivars Show Diversity of Root Morphologies with the Potential for Better Capture of Nitrogen

The worldwide demand for vegetable oils is rising. Oilseed rape (Brassica napus) diversifies cereal dominated crop rotations but requires important nitrogen input. Yet, the root organ offering an untapped opportunity to improve capture in soil. This study evaluates three culture systems controlled environment, observe morphology and identify attributes superior biomass production use. phenotypic diversity a panel of 55 modern winter oilseed cultivars was screened response two divergent nitrate supplies. Upon vitro hydroponic cultures, large variability morphologies observed. Root morphological traits positively correlated with shoot or leaf area. activities high-affinity transport negatively area, while combined high- low-affinity total length. X-ray computed tomography permitted visualize system pipes filled phenotype at germination stage indicative lateral deployment soil-grown plants. highlights great genetic potential rape, which could be manipulated optimize characteristics substantial implications agricultural production.
