Inducible plant resistance against herbivores is becoming a paradigm of plant–herbivore ecology. Fundamental to understanding induced resistance and its evolutionary ecology is specificity of ‘‘induction’’ and ‘‘effects’’. Specificity in the induction of resistance refers to whether plant damage by various herbivores causes the same response in plants. Specificity in the effects of induced resi...

Other common name(s): couchgrass, wheatgrass diet, agropyron Scientific/medical name(s): Raphanus sativus. The common name "radish" is derived from Latin radix (root). Description The radish is an edible root vegetable of the Brassicaceae family that was domesticated in Europe in pre-Roman times. Radishes have numerous varieties, varying in size, color and duration of required cultivation time...

Using cultivation, immunofluorescence microscopy, and scanning electron microscopy, we demonstrated the presence of viable enterohemorrhagic Escherichia coli O157:H7 not only on the outer surfaces but also in the inner tissues and stomata of cotyledons of radish sprouts grown from seeds experimentally contaminated with the bacterium. HgCl2 treatment of the outer surface of the hypocotyl did not...

The relationship among gibberellins, C vernalization, and photoperiod in the flowering response of radish, Raphanus sativus L., cv. Miyashige-sofuto, was studied. The optimal condition for flowering was vernalization and a 16-hour photoperiod; GA3 had no additional effect. Gibberellin A3 (60 ,jg total) was not able to induce flowering in nonvernalized plants grown on 8-hour days, but it did inc...

plant tissue culture technique could provide sterile and controllable condition in order to assay direct effect of different compounds on plant growth accurately. in this study, the effects of aqueous extracts prepared from roots and shoots of goosefoot (chenopodium album l.), redroot pigweed (amaranthus retroflexus l.), fennel (foeniculum vulgare), and wormwood (artemisia absinthium l.) were e...

this research was conducted on polluted soil near the lead and zinc factory in zanjan province through which the effects of two organic and three mineral sources were examined on heavy metals fixation in randomized experiment design. experimental treatments includes bagasse and rice husk in three levels: 1.25, 2.5 and 5%, zeolite in three levels: 5%, 10% and 15%, phosphate rock in three rates: ...

abstract in recent years some research results have appeared that exogenous salicylic acid provided significant mitigation effect against salinity induced injuries in plants. an experiment was conducted to investigate the effects of salt stress and salicylic acid on radish (raphanus sativus l.) plants. after appearing first leaves, plants were treated by salicylic acid (0.2 mm) for 3 days and n...

Selenium-enriched Japanese radish sprouts (Se-enriched JRS), in which Se-methylselenocysteine accounted for 80% of Se compounds, inhibited mammary tumorigenesis induced by 7,12-dimethylbenz[a]anthracene in rats. The effects of Se-enriched JRS on the oxidative stress-scavenging enzymes were investigated in rats. F344 female rats were fed test diets, in which Se-enriched JRS was added at 0, 2.4, ...

Identification of quantitative trait loci (QTLs) governing morphologically important traits enables to comprehend their potential genetic mechanisms in the genetic breeding program. In this study, we used 210 F2 populations derived from a cross between two radish inbred lines (Raphanus sativus) "835" and "B2," including 258 SSR markers were used to detect QTLs for 11 morphological traits that r...
