In this report, we demonstrate that sodium hydrosulfide (NaHS), a hydrogen sulfide (H(2)S) donor, promoted adventitious root formation mediated by auxin and nitric oxide (NO). Application of the H(2)S donor to seedling cuttings of sweet potato (Ipomoea batatas L.) promoted the number and length of
Potato color turns to brown after some process such as peeling, cutting, and slicing. In this research, the effect of acid-heat coagulated whey and commercial whey solutions on the color, polyphenol oxidase, phenylalanine ammonia-lyase activity, malondialdehyde, hydrogen peroxide content of potatoes
Wash water from 66% of 401 samples of fresh fruits and vegetables collected in the marketplace and affected by bacterial soft rot were positive for suspected strains of Salmonella, i.e., black, hydrogen sulfide-positive colonies on Salmonella-Shigella agar incubated for 24 h at 37°C. By comparison,
Anaerobic digestion of multiple waste vegetables collected from an organic farm in Central Illinois was carried out using a new cartridge design anaerobic digestion system. Waste vegetables, including carrot, cucumber, bell pepper, onion, lettuce, and potato, were chopped and then mixed together to
During a survey of potato scab pathogens in China from 2003 to 2012, a new pathogen was found in Shanxi and Neimenggu provinces. The incidence was approximately 20% of all recovered strains. The lesions caused by the pathogen were slightly raised and similar to those caused by Streptomyces scabies
Enriched wash from healthy and decayed portions of 341 fruits and vegetables collected in the marketplace and affected by fungal rots were tested for suspected Salmonella appearing as black, hydrogen sulfide-positive colonies on Salmonella-Shigella agar incubated at 37°C. Suspected Salmonella
During the spring of 2004 and 2005, angular leaf spot was observed on cucumber (Cucumis sativus L.) in some areas of Kurdistan Province in Iran for the first time. Disease incidence in affected fields was approximately 100%. Symptoms were initially small, round or irregular, water-soaked spots on
Pumpkin (Cucurbita pepo L., cv. Magic Lantern) and watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai, cvs. Millionaire and Sangrea) plants with wilting leaves and collapse of entire vines were observed during the 2005 and 2006 growing seasons in several fields in southwestern New Mexico
Colorimetric and fluorescent detection of cyanide and hydrogen sulfide ions has been effected using a simple organic probe in H2O:DMSO (20:80, v/v) medium. The probe exhibits a colour change from pale-yellow to red upon addition of these analytes under normal light and fluorescent change
Oil pumpkin (Cucurbita pepo L.) is commonly used for oil production, mainly in central and eastern Europe (1). In Serbia, it grows only in the north (Vojvodina Province), up to 1,500 ha. In June 2008, typical bacterial spot symptoms (dark green, water-soaked, transparent and greasy spots with yellow
Leaf blight symptoms on coriander (Coriandrum sativum) were observed during the summers of 2000 to 2002 in fields at the Beidou and Sijhou townships, Changhua County, Taiwan. Symptoms first appeared as small spots on the lower sides of leaves and stems. The centers of the spots quickly turned brown
