From: Eriodictyol can modulate cellular auxin gradients to efficiently promote in vitro cotton fibre development

Fig. 2

ERI significantly promotes in vitro fibre development. (a) The fibre phenotype of ovules cultured in BT medium supplemented with various concentrations (0, 2, 5, 10, 20 and 40 μM) of ERI NAR, DHQ and DHK for 10 days. The white line represents the scale bar, 5 mm. (b) Fibre length and (c) TFU in response to different concentrations of the four flavonoids were plotted as bar plots. For b-c, error bars indicated the SD of 5 biological repeats. Significant differences are presented as lowercase letters. (d) Fibre initials were visualized of control and ERI treated ovules after 1 day of incubation using SEM, the scale bar represents 100 μm. (e) YZ1 0 DPA ovules were cultured and photographed after 5 and 10 days. For both conditions, the cultured ovules are shown in dishes on the top, while the fibre phenotype of cultured ovules is shown in the lower image, scale bar, 5 mm. (f) Fibre length and (g) TFU were determined in control and ERI treated ovules after 5 and 10 days of culture and are presented as bar plots. Probability values of significant difference based on the Student’s t test are indicated
