flooding/high water |
|
Roots in saturated soil may asphyxiate with ethanol accumulation. Affected roots when cut open have a sweet odor, reduced latex flow, glossy appearance and rot in storage (Nov77, cv.Jewel ), in sweetpotato, this is called 'sour'. |

asphyxiation |
|
Roots in saturated soil may asphyxiate with ethanol accumulation. Affected roots often have water soaked appearance with dark eyes. When cut open have a sweet odor, reduced latex flow, glossy appearance and rot in storage. Large root at left is healthy. (Nov77, cv.Jewel ) |

asphyxiation |
|
649 Roots in saturated soil may asphyxiate with ethanol accumulation. Affected roots often have water soaked appearance with dark eyes. When cut open have a sweet odor, reduced latex flow, glossy appearance and rot in storage (Nov77, cv.Jewel) |

high soluble salts |
|
Fertilizer burn. (Jun69, cv.Centennial) |
| 1563645 |
flooding/high water |
|
Standing water injury. Notice raised lenticels (Sep71, cv.Jewel). |
| 1563646 |
flooding/high water |
|
Standing water will kill the roots and then are colonized by fungi (Oct76, cv.Jewel). |

cold injury (low temperature) |
|
Roots injured by low temperatures usually do not produce latex when cut. Internally the flesh may be spongy and watery and later develop cavities and dark streaks followed by root rotting fungi (cv.Jewel, May78). |
| 1563642 |

cold injury (low temperature) |
|
Roots injured by low temperatures usually do not produce latex when cut. Internally the flesh may be spongy and watery and later develop cavities and dark color. Presence of Penicillium on the surface often indicates cold injury (cv.Jewel, Jan82). |

cold injury (low temperature) |
|
Roots injured by low temperatures usually do not produce latex when cut. Internally the flesh may be spongy and watery and later develop cavities and dark color. Notice blackening of veins. Presence of Penicillium on the surface often indicates cold injury (cv.Jewel, May78). |

genetic abnormalities |
|
Mutation or chimeras. Sprouts from chimeras and used for planting will produce a crop of roots with that color. A serious problem. |
