Genotypic variation in composition and antioxidant activity was evaluated using 25 cultivars, 5 each of white-flesh nectarines, yellow-flesh nectarines, white-flesh peaches, yellow-flesh peaches, and plums, at the ripe (ready-to-eat) stage. The ranges of total ascorbic acid (vitamin C) (in mg/100 g of fresh weight) were 5-14 (white-flesh nectarines), 6-8 (yellow-flesh nectarines), 6-9 (white-fl...

although wild safflower (c.oxyacantha, 2n=24) has not been studied to a very large extent, yet it is believed that it can be used as an important source of biotic and abiotic stress resistance genes for improvement of cultivated safflower (c.tinctorius l., 2n=2x=24). in this study, the crossability between these two (cultivated and wild safflower) species was evaluated as based upon morphology ...

Understanding the mechanism(s) that favour cooperation among individuals competing for the same resources provides direct insights into the evolution of grouping behaviour. In a hybrid zone between golden-/yellow-collared (Manacus vitellinus) and white-collared (Manacus candei) manakins, males form aggregations composed of white and yellow males solely to attract females ('mixed leks'). Previou...

background rice is common foodstuffs in iran. aflatoxin contamination of rice can be hazardous human health and causes economic problems. objectives determination of aflatoxin levels was investigated on the imported rice which is consumed as the main food in this area. materials and methods two hundred samples of imported rice consisting; yellow (100) and white (100) rice were selected randomly...

achaemenid glazed bricks of archaeological excavation of tall-e-ajori in persepolis city were studied by multiple instrumental analysis methods  such as xrf, xrd, sem-eds, icp and optical microscopy to identify the compositional features of glaze and brick body. glaze samples are apparently white and yellow  and this phenomenon are caused by the deterioration processes in burial environment, he...

OBJECTIVES Mechanical and structural characteristics of vulnerable plaques were evaluated using coronary angioscopy and intravascular ultrasound. BACKGROUND Mechanical stress and composition of plaques play an important role in plaque disruption. METHODS Thirty-eight lesions in 38 patients were examined pre-interventionally. The plaques were classified as either yellow or white using corona...

Pigmented potato cultivars were ranked by a consumer panel for overall acceptance, and acceptance of aroma, appearance, and flavor. Potatoes were analyzed for total phenolics, anthocyanins and carotenoids. Concentrations of total phenolics in yellow and purple potato cultivars were 2-fold greater (P < 0.001) than in the white cultivar. Anthocyanins were low to non-detectable in white and yellow...

In congenital color blindness the red-green discrimination is impaired resulting in an increased confusion between those colors with yellow. Our post-receptoral physiological mechanisms are organized in two pathways for color perception, a red-green (protanopic and deuteranopic) and a blue-yellow (tritanopic). We argue that the discrimination losses in the yellow area in congenital color vision...
