Polarity of Production of Polyphenols and Development of Various Enzyme Activities in Cut-injured Sweet Potato Root Tissue.
Investigation of polyphenol production in cut-injured sweet potato (Ipomoea batatas Lam. cv. Kokei 14) roots by histochemical and quantitative methods showed that polyphenols were produced in striking amounts in the proximal side of the tissue pieces (2 cm thick), but only in small amounts in cells of the distal side. In response to cut injury, formation of the enzymes related to polyphenol bio...
متن کاملChilling Injury of Sweet Potato Shoots Reduced by Prior Incubation of H2O2 and NaCl
Excised shoot tips of sweet potato (Ipomoea babatas L.) were incubated in H2O2 or NaCl aqueous solution for 24h or 48h prior to a 3-day chilling at 2.5°C. Severity of chilling injury was visually observed during a post-chilling 7-day recovery at 21°C, and scored at 0 to 5 (none to most severe injury). In the first experiment, when cv. Purple (PUR) sweet potato shoots were subjected to 3-day chi...
متن کاملDetection of sweet potato virus C, sweet potato virus 2 and sweet potato feathery mottle virus in Portugal.
Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA frac...
متن کاملSweet-potato Scurf
The scurf disease of the sweet potato (Ipomoea batatas) was first described by Halsted, who published a brief account of it in 1890. To the fungus he gave the name Monilochaetes infuscans, a new genus and species, of which, unfortunately, he gave no technical description. For many years following his pioneer work little or no attention was given to sweet-potato diseases. This very common and in...
متن کاملLocalization of sweet potato chlorotic stunt virus (SPCSV) in synergic infection with potyviruses in sweet potato.
Among diseases reported worldwidely for sweet potato (Ipomoea batatas (L) Lam) crop, one of the most frequent is the Sweet potato virus disease (SPVD), caused by sweet potato chlorotic stunt virus (SPCSV) and sweet potato feathery mottle virus (SPFMV) co-infection. In Argentina, there exists the sweet potato chlorotic dwarf (SPCD), a sweet potato disease caused by triple co-infection with SPCSV...
