OBJECTIVE Very recent studies have reported positive effects of dietary nitrate on the oxygen consumption during exercise. This research aimed to study the effect of moderate dose of high-nitrate vegetables, watercress (Nasturtium officinale) and red radish (Raphanus sativus) compared with a control group on the incremental treadmill exercise test following a standard Bruce protocol controlled ...

Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv. Wheeler), a popular cover crop in the region, with reg...

The present study was based on the hypothesis that Boron (B) induces changes of other micronutrients in soil-plant systems. A preliminary study was carried out in sand culture growing radish (cv. French breakfast) as a test crop, under green house conditions. The experiment was laid out in a randomized complete block design and replicated three times. Boron was applied at the rate of 0, 0.25, 0...

Radish (Raphanus sativus L.) is an important annual or biennial root vegetable crop. The fleshy taproot comprises the main edible portion of the plant with high nutrition and medical value. Molecular biology study of radish begun rather later, and lacks sufficient transcriptomic and genomic data in pubic databases for understanding of the molecular mechanism during the radish taproot formation....

The carbohydrate moieties of arabinogalactan proteins (AGPs) are essential for their physiological functions and undergo rapid turnover in vivo. Degradation of the carbohydrate moieties of AGPs seems to occur by concerted action of several glycosidases, among them a-L-arabinofuranosidase, b-Dgalactosidase, and b-D-glucuronidase. Here, a bifunctional a-L-arabinofuranosidase/b-D-xylosidase from i...

There are many potential risks to human health from heavy metal contamination of vegetables resulting from wastewater irrigated sites. This study was carried out to assess the concentration of chromium (Cr) and the risk to human health by chromium through the intake of locally grown vegetables collected from wastewater irrigated agricultural fields. Twenty-seven samples of 9 (nine) different ty...

Abstract Radish downy mildew (DM) caused by the oomycete Hyaloperonospora brassicae f. sp. raphani is a serious problem in radish crop, an edible root vegetable of Brassicaceae family. The objective this research was to assess germplasm for DM resistance and evaluate response different organs disease under controlled conditions. Forty-four accessions were inoculated at cotyledons true-leaves wi...

BACKGROUND Heavy metals are ubiquitous elsewhere in nature and their measurement in environment is necessary to develop health management strategies. In this study, we aimed to find out concentrations and spatial patterns of heavy metals in main farms of Sanandaj in Kurdistan, Iran. METHODS Over May to October 2012, six farms were selected to analyze concentrations and spatial patterns of sev...

The possible toxicity of a commercial chlorine dioxide preparation (Halox E-100) was evaluated on radish and lettuce seedlings growing in pots under controlled conditions. A single application of various dilutions to radish seedlings growing in a sterile or nonsterile commercial plant substrate only slightly decreased plant dry weight. At the end of the experiments, the plants appeared unaffect...
