Fig. 3From: A simple method for the application of exogenous phytohormones to the grass leaf base protodermal zone to improve grass leaf epidermis development researchCharacteristics of the cells at areas of maize leaf protoderm after 2,4-D treatment. A The average cell length at the cell proliferation stage after 2,4-D (0.4 mg/ml) treatment was significantly larger than the mock. Bars indicate mean (± SD) (n = 150). B The average cell width at the cell proliferation stage after 2,4-D (0.4 mg/ml) treatment was significantly larger than the mock. (C) The GMCs number was repressed after 2,4-D (0.4 mg/ml) treatment. Bars indicate mean (± SD) (n = 46). *** indicates significant difference within each group (i.e., p < 0.001) using the Student’s t-testBack to article page
