First callose plug position in parents and F1 progeny of reciprocal crosses. (A), (C) and (E) show average first interval length of parents and F1s of reciprocal crosses. Comparisons between Col, C24 and their F1 progeny are shown in (A); comparisons between Ws, C24 and their F1 are shown in (C); comparisons between Col, An and their F1 are shown in (E). (B), (D) and (F) show distribution of the first interval length of parents and F1s of reciprocal crosses. Comparison between Col, C24 and their F1 (B); comparison between Ws, C24 and their F1 (D); comparison between Col, An and their F1 (F). The percentages in (B), (D) and (F) represent the proportion of pollen tubes with the first interval ≥150μm. ANOVA and multiple comparisons with LSD (least significant difference) were performed. Error bars in (A), (B) and (E) are SEM. Letters indicate significant differences at P<0.5. Values followed by the same letter are not significantly different.
