Exogenous ethylene inhibits sprout growth in onion bulbs.
BACKGROUND AND AIMS Exogenous ethylene has recently gained commercial interest as a sprouting inhibitor of onion bulbs. The role of ethylene in dormancy and sprouting of onions, however, is not known. METHODS A cultivar (Allium cepa 'Copra') with a true period of dormancy was used. Dormant and sprouting states of onion bulbs were treated with supposedly saturating doses of ethylene or with th...
متن کاملChilling Effect on Soluble Sugars, Respiration Rate, Total Phenolics, Peroxidase Activity and Dormancy of Onion Bulbs
Besides onions being one of the most cultivated and consumed vegetables, during storage onion bulbs are still affected by many physiological, biochemical and technological factors which can influence their quality. Respiration rate (RR O2 ), soluble sugars (SS), total phenolics (TP), and peroxidase (POD) activity were measured in inner bud tissues during a dormancy break of onion bulbs treated ...
متن کاملInhibitory Effects of Aqueous Onion and Garlic Extracts on Growth and Keratinase Activity in Trichophyton mentagrophytes
The effect of onion and garlic extracts on fungal growth and keratinolytic activity was studied in Trichophyton mentagrophytes as one of the major etiologic agents of human and animal dermatophytosis in Iran and other parts of the world. In order to find out the best keratinase producer for further steps, culture conditions for 30 strains of T. mentagrophytes isolated from human dermatophytosis...
متن کاملEffect of Maleic Hydrazide on Respiratorion of Stored Onion Bulbs
The respiration rate (RR) (CO2 production), activation energy (Ea) and Q10 of maleic hydrazide-treated onion bulbs (Allium cepa, cv. Rouge Amposta) at 20.10-6 mol.L-1 (MH1) and 45.10 -6 mol.L-1 (MH2) were measured at 4, 10 and 20oC. Immediately after treatment, the Q10 of MH-treated and control bulbs were not significantly different. After 8 weeks of storage, Q10 of control and both MH-treated ...
متن کاملFructo-oligosaccharide effects on blood glucose: an overview.
PURPOSE To identify the current status of scientific knowledge in fructo-oligosaccharides (FOS), non-conventional sugars that play an important role in glycemia control. METHODS We performed a search for scientific articles in MEDLINE and LILACS databases, from January 1962 to December 2011, using English/Portuguese key words: "blood glucose/glicemia", "prebiotics/prebióticos" and "dietary fi...
