Effects of different solvent extracts on the growth of mustard seedlings. Note: a: Effects of different solvent extracts on the root length of mustard seedlings. b: Effects of different solvent extracts on the height of mustard seedlings. c: Effects of different solvent extracts on the fresh weight of mustard seedlings. d: Effects of different solvent extracts on the allelopathy response index of mustard seedlings. e: Effects of different solvent extracts on the combined comprehensive allelopathy index of mustard. The same lowercase letters in the graphs indicate nonsignificant differences between treatments, and different lowercase letters indicate significant differences between treatments (P < 0.05)
