Kinds of seed: Alfalfa, alyceclover, asparagusbean, beans ( (a) Field bean, garden bean, lima bean, mung bean, asparagusbean, and cowpea. (1) General description. (i) Germination habit: Epigeal dicot. (ii) Food reserves: Cotyledons which are large and fleshy. (iii) Shoot system: The hypocotyl elongates and carries the cotyledons above the soil surface. The epicotyl elongates, causing the terminal bud to emerge from between the cotyledons; the primary leaves expand rapidly. (iv) Root system: A long primary root with secondary roots. (2) Abnormal seedling description. (i) Cotyledons: (A) For garden bean ( ( ( (B) All other kinds: ( ( (ii) Epicotyl: (A) Missing. (B) Deep open cracks. (C) Malformed, such as markedly curled or thickened. (D) Less than one primary leaf. (E) Primary leaves too small in proportion to the rest of the seedling, usually associated with visible defects of, or damage to, the main stem of the epicotyl. (F) Terminal bud missing or damaged. (If a few seedlings with total or partial decay to the epicotyl are found, they may be classified as normal, provided the hypocotyl and root are normal. The epicotyl on such seedlings usually does not decay when grown in a fairly dry environment and exposed to light. A retest, preferably in soil or sand, will aid in interpretation of such seedlings.) (iii) Hypocotyl: (A) Deep open cracks extending into the conducting tissue. (A healed break, sometimes referred to as a “knee,” is considered normal.) (B) Malformed, such as
