Varietal Screening of Short Day Onions (Allium cepa L.) under Coastal Saline Area

Towards the transformation of onions (Allium cepa)

This review outlines the potential for developing a reliable transformation system for onions (Allium cepa). A summary of the onion tissue culture literature is presented along with descriptions of the gene transfer systems available. The most suitable regulatory sequences and selective genes that could be used for onion transformation are described, together with the problems which may be enco...

Antimicrobial activity of essential oil extracts of various onions (Allium cepa) and garlic (Allium sativum)

Antimicrobial activity of different concentrations (50, 100, 200, 300 and 500ml/l) of essential oil extracts of three type of onions (green, yellow and red) and garlic against two bacteria, Staphylococcus aureus, Salmomella Enteritidis, and three fungi, Aspergillus niger, Penicillium cyclopium and Fusarium oxysporum, was investigated. The essential oil (EO) extracts of these Allium plants (garl...

Assessment report on Allium cepa L., bulbus

Quercetin and isorhamnetin glycosides in onion (Allium cepa L.): varietal comparison, physical distribution, coproduct evaluation, and long-term storage stability.

During onion processing, the outer dried protective layer (outer paper layer) and first two fleshy leaf layers are removed. This coproduct material is a potential commercial source of flavonoids especially quercetin. In the following study, the flavonoid composition was determined in coproduct materials and the press cake (material generated after juice extraction) in several commercially impor...
