BACKGROUND Vegetables constitute a vital part of the human diet, being the main source of minerals, vitamins, dietary fibre and phytochemicals. They however, also contain nitrates and nitrites, which adversely affect human health. OBJECTIVE To determine nitrate and nitrite content in selected vegetables purchased at supermarket chains in Siedlce and to assess their impact on consumer health. ...

Few previous studies document effects of herbivores on the reproduction of wild plants in situ. We examined the impact of aphids' on seed production in wild radish (Raphanus sativus L.), an annual herb. Aphid infestation increased during the three-month flowering period. Flower and fruit production declined during the season, in part due to aphids. Inflorescences of lateblooming plants more tha...

From October 1987 to August 1988, 1,000 tests were conducted on 10 types of fresh produce from two Minneapolis area supermarkets to detect Listeria spp. The produce included broccoli, cabbage, carrots, cauliflower, cucumbers, lettuce, mushrooms, potatoes, radishes, and tomatoes. The vegetables were tested by the Food and Drug Administration method for isolation of Listeria spp., with the additi...

Abstract The aim of this study was to explore the antibacterial and antioxidant efficacy nickel oxide nanoparticles (NiO NPs). Raphanus sativus ( R. ) extract mediated NiO NPs were calcined at 100, 300, 600 900 ? in a muffle furnace for 3 h. increased intensity diffraction bands X-ray (XRD) spectrum suggest that degree crystallinity increases with increasing calcination temperature. desired ele...

Abstract A radish panel of 152 accessions with diverse root shapes was assembled from the National Plant Germplasm System (NPGS) collection based on weighted geographical sampling. Accessions represented 35 countries and were categorized into eight regions—North America, Europe, Africa, West Asia, Central South East Southeast Asia. Multiple plants per accession assayed using genotyping by seque...
