Values are the mean of triplicates. Mean values followed by different letters are significantly different within a row or column at 5% probability level; that is, α = 0.05 () according to Duncan statistics. Group 1: water, Group 2: DMSO and water mixture, Group 3: 2,4-D, Group 4: lanthanum nitrate, Group 5: HL, Group 6: La (III) complex.
