Seed production was altered in <i>nhx5 nhx6</i>.

<p>(A) Silique phenotype. Photos were taken for siliques on the main stem at 22 DAF. Bar = 0.5 cm. (B) Embryo morphology at 14 DAF. Bars = 1mm. (C) Silique length. Length of siliques on the main stem was measured (average length of 6 siliques) at 22 DAF. Error bars represent SD; n = 15. (D) Seed yield per silique. The total seeds per silique were counted (average number of 6 siliques). Error bars represent SD, n = 15. (E) Long diameter of dry seeds. Error bars represent SD, n = 250. (F) Thousand grain weight of seeds. Error bars represent SD, n = 8. (G) Silique yield per plant. The total siliques of each plant were counted. Error bars represent SD, n = 15. ***P≤0.001, by <i>t</i> test.
