Effects of different solvent extracts on the germination of mustard seeds. Note: a: Effects of different solvent extracts on the germination rate of mustard seeds. b: Effects of different solvent extracts on the germination potential of mustard seeds. c: Effects of different solvent extracts on the allelopathy effect index of mustard seeds. The same lowercase letters in the graphs indicate nonsignificant differences between treatments, whereas different lowercase letters indicate significant differences between treatments (P < 0.05)
