Onion bulbs accumulate fructans, a type of soluble carbohydrate associated with lower rates of colorectal cancers. Higher fructan concentrations in bulbs are correlated with higher pungency, longer dormancy, and greater onion-induced antiplatelet activity (OIAA). We analyzed replicated field trials of a segregating family for types and concentrations of soluble carbohydrates in onion bulbs 90 d...

Development of insecticide resistance in onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), populations in onion (Allium spp.) fields and the incidence of the T. tabaci transmitted Iris yellow spot virus have stimulated interest in evaluating alternative management tactics. Effects of straw mulch applied in commercial onion fields in muck areas of western New York were assessed in ...

We have attempted to make the gas hydrate crystal in vegetable in order to extend the shelf life of fresh vegetable as preservation technique instead of freezing. As a result, it was confirmed that gas hydrate can be formed in onion tissue at 5 o C by pressurizing between 0.4 and 0.8 MPa Xe pressure. However, the detail conditions regarding to gas hydrate formation in vegetable tissue and their...

high correlation (r 0.89); the corresponding value for the colorimetric method was r 0.70. A highly significant correlation (r -0.97) between pyruvate (P,) and the olfactory threshold concentration of onion juice has been observed by Schwimmer & Guadagni (1962). The importance of thiolsulphinate as an unstable intermediate in the production of the components of onion that contribute to its flav...

From analysis of the high Q modes in a Bragg onion resonator with an omnidirectional reflector cladding, we establish a close analogy between such a resonator and a spherical hollow cavity in perfect metal. We demonstrate that onion resonators are ideal for applications that require a large spontaneous-emission factor beta, such as thresholdless lasers and single-photon devices.

introduction: neuropathic pain is one of the common complications of diabetes mellitus which is caused by impairment in nerve conductivity. the role of flavonoid and polyphenol compounds in treatment of neuropathic pain has been revealed, and extract of onion contains significant amounts of these compounds. the aim of this study was to investigate the effect of alcoholic extract of onion on dia...

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...

For evaluation of Iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 Iranian onion morphotypeswere collected from East Azarbaijan (RedAzarshahrmorphotypes), Tehran (Red Rey morphotypes), Razavi Khorasan (Red Neyshaboormorphotypes) and Zanjan (Gholyghese morphotypes). These onion morphotypes were planted inRCBD design in four replications in Seed and P...

A temperature-driven process model was developed to describe the seasonal patterns of populations of onion thrips, Thrips tabaci Lindeman, in onions. The model used daily cohorts (individuals of the same developmental stage and daily age) as the population unit. Stage transitions were modeled as a logistic function of accumulated degree-days to account for variability in development rate among ...
