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 کاملdesign, installation and evaluation a automatic atmosphere controlled cold storage
one way to increase the shelf life of agriculture products is using of controlled atmosphere storages. in order to obtain the controlled gas components, an equipped cold store with cooling system and atmosphere controller system designed and constructed. the injection of co2, o2 and n2 were controlled automatically into the store by programable logic control (plc). the store was a laboratory re...
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 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 کاملPhenylalanine 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 ...
