Concentration of engineered nickel oxide nanoparticle (NiO-NP) in nature is on the rise, owing to large scale industrial uses, which have accreted the scope of its exposure to plants, the primary producers of the ecosystem. Though an essential micronutrient for the animal system, supported by numerous studies confirming its toxicity at higher dosages, nickel oxide is graded as a human carcinoge...

This study comprises the optimization and validation of a new TLC method for determination of flavonols in the bulbs of seven cultivars of onions and shallots. Separation was performed on RP-18 plates with the solvent mixture tetrahydrofuran/water/formic acid (40+60+6, V/V/V) as a mobile phase. The method was evaluated for precision, linearity, LOD, LOQ, accuracy and robustness. Chromatographic...

Ground and whole Ditylenchus dipsaci maintained on onion callus contain no culturable micro-organisms when tested with five check media. Healthy onion callus does not produce pectolytic enzymes. Pectolytic enzymes are present in infected callus. These enzymes are, however, associated with resident nematodes and not host tissues. These results suggest that D. dipsaci is the actual source of the ...

Antimicrobial properties of phytochemicals extracted from onion (Allium cepa) and ginger (Zingiber officinale) were evaluated against Escherichia coli and Staphylococcus aureus, two common food borne pathogens. They were tested using minimum inhibitory concentration, minimum bactericidal concentration disc diffusion and agar wells diffusion. Onion showed good antimicrobial properties against S....

Epidemiological studies link increased garlic (Allium sativum) consumption with a reduced incidence of colon cancer in various human populations. Experimental carcinogenesis studies in animal models and in cell culture systems indicate that several allium-derived compounds exhibit inhibitory effects and that the underlying mechanisms may involve both the initiation and promotion phases of carci...

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...
