Exogenous ERI treatment promotes in vitro fibre development. (a) The fibre phenotype of 10-day-cultured ovules without or with different flavonoids treatments, i.e., control, ERI, NAR, DHQ, DHK, Q and K. The white line represents the scale bar, 5 mm. (b) Fibre length after 10 days of culture from in response to different flavonoid treatments. (c) Total fibre unit (TFU) in 10-day-cultured ovules in response to different flavonoids. For b-c, error bars indicate SD for three repeats, and lowercase letters present significant differences between the treatments
