Allium vegetables have been employed for a long time in traditional medical practice to treat a variety of diseases. Onion (Allium cepa L.), one of the representative Allium vegetables, has been used for centuries for its pungency, flavoring value, and medicinal properties. The bulb of onion is used medicinally and has been consumed as seasoning food for many centuries (Sengupta et al., 2004). ...

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...

In today’s Internet, trust has been widely used to design anonymity and security enhanced systems. Some of these trust-based systems have been successfully deployed in the Internet for a long time and benefit a large population of Internet users. In particular, trust-based onion routing network is a representative example for the use of trust in protecting anonymity. As one of the most popular ...

abstract in order to detect onion yellow dwarf virus in khorasan province in iran, onion samples from major onion growing regions where collected in spring and summer 2010. to determine the distribution of the virus, samples were randomly taken from onion fields in vicinity of mashhad, chenaran, quchan, torbate heydarye, neyshabur, bardaskan, gonabad, fariman, faruj, shirvan, bojnourd and ash k...

To exploit the polymorphism of repeat numbers in short tandem repeat (STR) sequences (microsatellites) as molecular markers, STRs must be isolated and PCR primers must be developed in flanking sequences. In species with large genomes such as Allium cepa L. (onion and shallot), an efficient selection procedure for genomic fragments containing STRs is a crucial step. Here we describe a nonradioac...

The intensity of mitogenetic radiation was estimated from data given by Gurwitsch. The sensitivity of the biological method and of the physical methods were compared. With onion-base pulp and onion roots as mitogenetic inductors, the photographic method gave no perceptible blackening for exposures up to 184 hours. A photoelectric counter tube was described with cadmium as photoelectric metal. I...

Black mold disease caused by Aspergillus niger V. Tiegh. is the most devastating infection occurs in onions (Allium cepa L.) under field and store conditions. The use of biocontrol agents is ecofriendly approach for controlling seedborne and soilborne diseases compared to the use of toxic synthetic fungicides. This study has been designed to assess the contamination levels of onion seeds with A...

This experiment was carried out to investigate effects of onion extract on growth performance, meat quality and blood profiles of White mini broilers. Total of 600 one-d-old male White mini broiler chicks were divided into four groups and fed control diets (non-medicated commercial diet or antibiotics medicated) or experimental diets (non-medicated diets containing 0.3% or 0.5% onion extract) f...

Research was carried out on antibacterial activity of Allium cepa. Two different extracts were made from Allium cepa (onion) using distilled water. The extracts include fresh onion extract and cold water extract. The antibacterial activity of the onion was tested on four bacteria isolates associated with various ocular infections. The bacterial isolates include: Escherichia coli, Staphylococcus...
