Fig. 5From: Root morphology and seed and leaf ionomic traits in a Brassica napus L. diversity panel show wide phenotypic variation and are characteristic of crop habitLeaf and seed element concentration ratios of Brassica napus grown in compost. Data are means of up to 385 and 380 genotypes, for leaf and seed concentrations, respectively, including winter OSR (n = 163), spring OSR (n = 127), semiwinter OSR (n = 7), winter fodder (n = 15) and swede (n = 35) habits. Boxes represent the mid two quartiles with the median drawn; whiskers are the 95 % confidence limits plus extremes. Ratios are calculated, e.g. for Ca:Sr, as ([S]seed/[Mo]seed) / ([S]leaf/[Mo]leaf). Panels a–d represent different element pairsBack to article page
