The onion (Allium cepa L.) is widely planted worldwide as a valuable vegetable crop. The scales of an onion bulb are a modified type of leaf. The one-layer-cell epidermis of onion scales is commonly used as a model experimental material in botany and molecular biology. The lower epidermis (LE) and upper epidermis (UE) of onion scales display obvious differences in microscopic structure, cell di...

Pantoea ananatis is a member of the family Enterobacteriaceae and an enigmatic plant pathogen with a broad host range. Although P. ananatis strains can be aggressive on onion causing foliar necrosis and onion center rot, previous genomic analysis has shown that P. ananatis lacks the primary virulence secretion systems associated with other plant pathogens. We assessed a collection of fifty P. a...

Two onions (Sulfur-1 and Sulfur-4) cultivated with different sulfur applications were thermally processed to elucidate the effects of heat treatment on browning index and antioxidant activity. Sulfur-4 onion had higher sulfur content compared with the Sulfur-1 onion. After thermal processing, browning intensity was different between the two onions juices, with lower values observed for Sulfur-4...

Drying is one of the most conventional methods used for and before preservation storage. It also improves post-harvest quality value addition product. This present evaluate feasibility a solar tunnel dryer preparing onion powder. The study aims to minimize storage losses provide cheap alternative open sun drying. Solar drying would create an income source in rural area, especially farmers, can ...

Increasing onion yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the consumers. Two field experiments were carried out during two successive seasons; 2011/2012 and 2012/2013 at the experimental station of National Research Centre, Beheira Governorate (North of Egypt) to find out the influence of some bio-stimulants i.e., yeast extrac...

Onion bulb crop production using sets as planting material has been increasing for the last decade in response to high demand and because of their yielding capacity adaptability continuously changing growing environment. The objective this experiment, therefore, was investigate effect seed rate on yield quality onion setsas a highly demanded material. Treatments comprised two cultivars (Kamlin ...

Onion (Allium cepa) bulb from Liliaceae has antioxidant, spasmolytic and antihypertensive activities. The aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. Onion peel powder was extracted by maceration in 70% alcohol for 72 h. A terminal portion of ileum from male Wistar rat was dissected and its contractions were recorded isotonically in...

This study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in Ross and Cobb broiler chickens. One hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (Ross-308 and Cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. The experimental grou...

Onion (Allium cepa) consumption has been remarked in folk medicine which has not been noted to be administered so far as an adjunct to conventional doxorubicin-based chemotherapy in breast cancer patients. To our knowledge, this is the first study aimed to investigate the effects of consuming fresh yellow onions on hepatic enzymes and cancer specific antigens compared with a low-onion containin...
