Phenylalanine Ammonia-lyase, Peroxidase, Pyruvic Acid and Total Phenolics Variations in Onion Bulbs During Long-term Storage
Phenylalanine ammonia-lyase (PAL) and peroxidase (POD) enzyme activities, total phenolics and pyruvic acid (PA) (as pungency indicator) were measured in onion bulb tissues (c.v. Rouge Amposta) during storage at 4 and 20 3C. After 2 wk, PAL activity increased at 4 3C, but decreased at 20 3C, and after 4 wk, PAL activity at 20 3C was higher than activity observed at 4 3C. Peroxidase activity was ...
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 کاملExogenous 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 کاملMalformin in Aspergillus niger-infected onion bulbs (Allium cepa).
Malformin was identified, by its biological activity and chromatography, in acetone extracts of the outer scales of onion bulbs infected with Aspergillus niger. Malformin was not detected in tissue underlying the infected areas or in the central portions of the bulbs, nor was malformein liberated from extracts or extracted tissues after reduction with zinc in acetic acid. This is the first repo...
متن کاملRecycling gamma irradiated sewage sludge as fertilizer: A case study using onion (Alium cepa)
Recycling sewage sludge into fertilizer for agricultural purposes may improve soil fertility by influencing the physical, chemical, and biological properties of the land. However, there is concern regarding elevated levels of heavy metals and pathogenic microorganisms, which may result from the use of untreated sewage sludge. Gamma radiation is found to be an efficient tool in the hygienization...
