Fig. 7

Mean oil droplet density (number of oil droplets/mm2), determined from root thin section slices of valerian. Shown are four cloned elites (CE1, CE2, CE3, CE4) (A), two root classifications (thin- and thick-rooted) (B), four root diameter fractions (RF1, RF2, RF3, RF4) (C) and three horizons (HZ1, HZ2, HZ3) (D). Further details of the cloned elites, the root classification, the root diameter fractions and horizons are shown in the text. Vertical lines: standard deviation. Significant codes: *< 0.05, **< 0.01, ***< 0.001. Different small form letters mark significant differences between the oil droplet densities (p <  0.05, SNK). Number of root slices given in Table 2
