Effect of spraying different concentrations of CuFe-LDHs and RW on the phenotype of lettuce after one month. a Lettuce treated with varying concentrations of LDHs and RW. b Fresh weight of leaves. c Dry weight of leaves. d Moisture content. e Leaves number. f Plant height. g Plant width. Error bars represent SD. CuFe-LDHs = 1, 10, and 100 μg/mL correspond to LDH1, LDH10, and LDH100 for short. RW = 1, 10, and 100 μg/mL are RW1, RW10, and RW100 for short. *p < 0.05, ***p < 0.001, and ****p < 0.0001, Student’s t-test. Bar = 20 cm
