Figure 8 in Pericarp-mediated chemical dormancy controls the fruit germination of the invasive hoary cress (Lepidium drobo), but not of hairy whitetop (Lepidium oppelionum)

Figure 8. The effect of afterripening and washing on the abscisic acid (ABA) and gibberellin (GA) levels of Lepidium drobo fruits.(A) Endogenous levels of ABA and bioactive GAs in fresh and afterripened dry seeds and pericarps. (B) ABA and bioactive GA levels during washing of fresh L. drobo fruits, as compared with afterripened fruits, and with the resultant maximum germination responses presented. Mean values ± SE (N = 3 × 25) of accessions KM 1296 and KM 1754 (2014 to 2015 harvest) at optimal germination assay conditions (12/12-h light regime at 25/15 C day/night for 28 d) are presented.N = 4 × 20 mg (dry weight,DW) of seed/pericarp for ABA and bioactive GA analysis. For a detailed statistical analysis of the ABA contents and their catabolites, see Supplementary Table S2.
