Seed development at high temperatures affects seedling viability. (A) Graph displaying the cumulative percentage of seed germination at 1, 2, 3, and 4 day after vernalization (DAV), and later for seeds produced by DH12075, Topas, Westar plants grown at CT and MT. (B) Percentage of defective seedlings per categories of defects: not viable (dark blue), with one cotyledon (red), asymmetrically positioned cotyledons (green), twin seedlings (turquoise), with one cotyledon, and defective root (purple), without any root (orange) and other categories (light blue). The analysis was performed on seedlings from seeds produced by DH12075, Topas, Westar plants grown at CT and MT. (C–I) Range of observed seedling phenotypes. A wild-type seedling is shown (C). Seedlings (D,E) are with one cotyledon (red). (F) The seedling is with two roots and two shoots (turquoise). (G) Zoom in of a seedling without root (orange). (H,I) Are shown seedlings from the other categories (light blue). The small colored square in the upper right corner refers to the categories. Scale bars represent 10 mm.
