EOs from E. benthamii diploid and autotetraploid germplasms tested in hytotoxicity bioassays. (a) GR (%) of L. sativa seeds after 48 h of exposition; (b) GSI of L. sativa seeds after 48 h of exposition; (c) RG (mm) of L. sativa seeds after 48 h of exposition; (d) SG (mm) of L. sativa seeds after 48 h of exposition; Positive control: glyphosate; negative control: water and dichloromethane. Germplasm: diploid 1 and 3 (lower and higher yield); autotetraploid A1 and A3 (lower and higher yield); autotetraploid B1 and B3 (lower and higher yield). The bars are 95% confidence intervals. Overlapped confidence intervals indicates that statistical difference was not detected.
