Figure 6 in Seedbank Persistence of Palmer Amaranth (Amoronthus polmeri) and Waterhemp (Amoronthus tuberculotus) across Diverse Geographical Regions in the United States

Figure 6. Interaction of experimental site by burial depth on percentage seed damage and loss averaged across 2014–2016 for Amoronthus polmeri and Amoronthus tuberculotus. Damaged seeds include broken, shrunk, or malformed seeds and those lost due to deterioration or futile germination, which were impossible to count. Vertical bars represent ± standard error of the mean. Supplemental information is also provided in Supplementary Tables S1 and S2, where the actual values averaged across three replications per treatment and five locations of seed material origins are shown.
