1563648 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'.
1563647 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 condition is called "sour."

1563685 edema Photomicrograph showing enlarged cells in a blister between the periderm and parenchyma, 100x. (Jan92)
1563662 boron deficiency Blister caused by boron deficiency appears as raised purple/brown spots.  Scurf spots may be similar but are not raised.  Spotting may occur internally especially near the vascular ring.  Blister may develop in storage.  (Feb92,cv.Beauregard)
1563663 boron deficiency Blister caused by boron deficiency appears as raised purple/brown spots.  Scurf spots may be similar but are not raised.  Spotting may occur internally especially near the vascular ring.  Blister may develop in storage.  (Feb92, Hernandez)
1563664 boron deficiency Blister caused by boron deficiency appears as raised purple/brown spots.  Scurf spots may be similar but are not raised.  Spotting may occur internally especially near the vascular ring.  Blister may develop in storage.  (Dec92, cv. Hernandez
1563665 boron deficiency Blister caused by boron deficiency appears as raised purple/brown spots.  Scurf spots may be similar but are not raised.  Spotting may occur internally especially near the vascular ring.  Blister may develop in storage.  (Feb92, cv. Hernandez)

1563641 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 streaks followed by root rotting fungi (cv.Jewel, Apr77).  
1563643 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, Dec70).  
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). 
1563633 cold injury (low temperature) Roots injured by low temperatures usually do not produce latex when cut (cv.Jewel, Dec70).
1563634 cold injury (low temperature) Roots injured by low temperatures usually do not produce latex when cut (cv.Jewel, Dec70).  
1563635 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).
