    (a) General description.

    (1) Germination habit: Epigeal dicot.

    (2) Food reserves: Leaf-like cotyledons and perisperm.

    (3) Shoot system: The hypocotyl elongates carrying the cotyledons 

above the soil surface. The epicotyl usually does not show any 

development within the test period.

    (4) Root system: A primary root; secondary roots may develop within 

the test period.

    (5) Seedling: Frequent counts should be made on multigerm beet since 

the growing seedlings will separate from the cluster making it difficult 

to identify the source. Any cluster which produces at least one normal 

seedling is classified as normal; only one normal seedling per cluster 

is to be counted (see Sec. 201.56(d)). Toxic substances from the 

clusters of beet and Swiss chard may cause discoloring of the hypocotyl 

and/or root. Seedlings which are slightly discolored are to be 

classified as normal; however, if there is excessive discoloration, 

retest by the method in Sec. 201.58(b)(3).

    (b) Abnormal seedling description.

    (1) Cotyledons:

    (i) Less than half of the original cotyledon tissue remaining 

attached.

    (ii) Less than half of the original cotyledon tissue free of 

necrosis or decay.

    (2) Epicotyl:

    (i) Missing. (May be assumed to be present if 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) None.

    (ii) Weak, stubby, or missing primary root with weak secondary or 

adventitious roots.

    (iii) For discolored roots of beet and Swiss chard, see Sec. 

201.58(b)(3).

    (5) Seedling:

    (i) One or more essential structures impaired as a result of decay 

from primary infection. (For discolored seedlings of beet and Swiss 

chard, see Sec. 201.58(b)(3).)

    (ii) Albino.
