Seedling emergence and remaining seeds at sediment burial depths.

Mean percentage of total emerged seedlings from unsorted (A) and sorted (B) seeds 2 months after planting at different sediment depths. Letters indicate significant difference (P<0.05) between depths. Mean percentage of total planted seeds that were viable, dead or unsuccessfully emerged after 2 months (C) and 6 months (E) for unsorted seeds, and after 2.5 months for large (D) and small (F) seeds, at the different seed burial depths.
