Photographs of root system architecture and average main and lateral root length and number of lateral roots in two Brassica oleracea accessions (C6 and F103) grown in a high throughput root phenotyping system for two weeks and supplied with solutions containing 0.025 mM P (Low P) and 0.25 mM P (High P). Length of lateral roots was determined in each quartile of the main root length, hence the three horizontal columns (in the fourth quartile there were no lateral roots). Numbers to the left of the columns indicate the average number of lateral roots per quartile. Data are means and standard errors. Scale bars indicate 1 cm
