66 | T-shaped pre-embryo with four cells | Yellowish white | 5.0 ± 0.2 | 6.0 ± 0.3 | 5.6 ± 2.7 | 87.0 ± 4.3 |
87 | The globular embryo forms, and the outside-layer cells of the outer integument begin to dehydrate and the suspensor starts to degenerate | Yellowish white | 44.0 ± 5.5 | 5.0 ± 0.9 | 6.5 ± 2.1 | 79.8 ± 2.1 |
108 | The inner testa disappears, and starch and lipid globules accumulate rapidly | A mixture of yellow and light brown | 66.0 ± 5.2 | 13.0 ± 3.5 | 9.0 ± 2.2 | 72.2 ± 1.1 |
122 | The embryo is fully mature with a compact testa and no further morphological changes | Brown dark | 37.0 ± 7.2 | 22.0 ± 4.1 | 14.4 ± 3.1 | 68.6 ± 2.6 |
