From: Auxin controls circadian flower opening and closure in the waterlily
Flower opening-closure pattern is regulated by auxin. a-c Floral movement angles were measured after treatment with NAA and TIBA (10 μM NAA/TIBA was pretreated for 8 h before time-lapse photography, and then 10 μM NAA/TIBA was sprayed on the intermediate segment and bottom segments of petal for every 2 h treatment). Scale bar, 25 mm (a). Error bar = SEM (b, c). Significant analysis of the maximum opening angles among the DMSO-, NAA- or TIBA-treated samples was performed by Student’s t-test. ****, p < 0.0001
