- (a) **General description.**
  - (1) **Germination habit—** Epigeal dicot.
  - (2) **Food reserves—** Cotyledons which expand and become thin, leaf-like and photosynthetic. In Brassica, Sinapis, and Raphanus, the cotyledons are bi-lobed and folded, with the outer cotyledon being larger than the inner.
  - (3) **Shoot system—** The hypocotyl elongates and carries the cotyledons above the soil surface; the epicotyl usually does not show any development within the test period.
  - (4) **Root system—** A long primary root.
- (b) **Abnormal seedling description.**
  - (1) **Cotyledons—**
    - (i) **Decayed at point of attachment.**
    - (ii) **Less than half of the original cotyledon tissue remaining attached.**
    - (iii) **Less than half of the original cotyledon tissue free of necrosis or decay.**
  - (2) **Epicotyl—**
    - (i) **Missing.** (May be assumed to be present if the cotyledons are intact.)
    - (ii) [Reserved]
  - (3) **Hypocotyl—**
    - (i) **Deep open cracks extending into the conducting tissue.**
    - (ii) **Malformed, such as markedly shortened, curled, or thickened.**
    - (iii) **Watery.**
  - (4) **Root—**
    - (i) **Weak, stubby, or missing primary root.** (Secondary roots will not compensate for a defective root.)
