457 Onion (Allium cepa L.) is an important export oriented vegetable among the cultivated allium in India. It is also known as “queen of kitchen”. Productivity of onion is affected by many biotic and abiotic stresses. For commercial cultivation of onion, both thrips and foliar diseases play the key role in reducing the bulb yield and quality of produce. Among the various foliar diseases affecti...

Top, tree or Egyptian onion, Allium x proliferum (Moench) Schrader, 2n=2x=16, is a minor, vegetatively propagated garden crop in Europe, North America and North East Asia. Several clones of the top onion were found to be locally cultivated in the region of South Croatia under the name “Ljutika-talijanka”. One of these, clone Biorina, was studied by means of both classi­ cal cytogenetic techniqu...

OBJECTIVE To examine the in vitro antibacterial activity of the ethanol extract of fresh fruits of Solanum incanum L., fresh leaves of Ricinus communis L. and Allium ampeloprasum var. porrum L., and to determine and quantify the phenol compounds of the investigated plant parts. METHODS This study was carried out at the Faculty of Science, King Khalid University, Abha, Kingdom of Saudi Arabia ...

Ruminal inoculum enriched with particle-associated microorganisms was collected from rumen cannulated Santa Inês wethers grazing tropical grass pasture and a supplement based on ground corn and soybean before feeding and used to evaluate effects of some commercial essential oils (EO) on ruminal fermentation and methane emission in vitro. The investigated EOs were orange EO (Citrus sinensis, CrS...

A complex approach for the environment health assessment integrating information on contaminants levels registered in environment compartments and bioindication-based estimates is developed and applied to two studies carried out at sites with different scenarios of long-term impact. The environment state is assessed at the territory of a nuclear waste storage facility, Obninsk, Russia, and in t...

N-nitroso compounds, such as N-nitrosodiethylamine (NDEA), can be formed by the reaction of secondary amines with nitrosating agents, and are suspected to be involved in tumors in humans. NDEA has been considered a weak carcinogen in genotoxic assays probably due to the inefficient nitrosamine activation system that is used and/or to the efficient repair system. In this work, we evaluated the s...

OBJECTIVE Allium hirtifolium (Persian shallot) has a hypoglycemic effect on diabetic animals. The aim of this study was to assess the effect of the ethyl acetate fraction of Allium hirtifolium on the function of isolated hearts of diabetic rats. METHODS The control and diabetic animals were randomly divided into four groups: saline- or extract-treated controls (n=10 and n=6, respectively) and...

Although the incidence of stomach cancer has been declining, it remains the second leading cause of cancer death worldwide. Potential protective effects of allium vegetables against cancer have been reported by a few epidemiologic studies in Chinese populations, but the sample sizes of these studies were relatively small. We examined the associations between allium vegetable consumption and sto...

Higher plants have been proposed as test organisms for the detection of genotoxic substances in the environment. Several plant test systems are already in use and are found to be as sensitive and reliable as other short-term tests. Allium cepa is one of these plants, which has been used in different studies to detect chromosome aberrations induced by chemicals. The use of non-animal test method...

The objective of the study was to summarize the methods for isolating and identifying natural sulfur compounds from Allium ursinum (ramson) and to discuss the active constituents with regard to antifungal action. Using chromatographic techniques, the active constituents were isolated and subsequently identified. Analyses by high-performance liquid chromatography (HPLC) suggested that these comp...
