Phenotypes of control, pTRV2-CaDTX35, and pTRV2-CaDFR plants. a Flower phenotypes of control, pTRV2-CaDTX35, and pTRV2-CaDFR plants. Scale bars, 1 cm. b Pollen viability of control, pTRV2-CaDTX35, and pTRV2-CaDFR plants. Scale bars, 100 μm. c Pollen grains of control, pTRV2-CaDTX35, and pTRV2-CaDFR plants were germinated in vitro. Scale bars, 100 μm. d SEM images of pollen grains. Scale bars, 10 μm. e Seeds in fruits. Scale bar, 1 cm. f Pollen germination rate in vitro. g Pollen-tube length. h Flavonoid content. i Total anthocyanin content. j Flavonol content. k H2O2 content. l MDA content. m Quantification of seed set. Error bars indicate mean ± standard error (n = 6) in f and g, mean ± standard error (n = 3) in h–l, and mean ± standard error (n = 20) in m. *P < .05, **P < .01.
