When washed at moderate temperatures, slices of many underground storage organs show a steady rise in their rate of respiration until it reaches a value two to five times that of freshly cut tissue. Laties (3) has recently reviewed our knowledge of these changes in respiration. In accordance with his suggestion, the respiration which develops gradually on washing will be referred to as induced ...

Most information on the biosynthesis of carotenoids is from experiments with fungi, especially Phycomyces blakesleeanus and Mucor hiemalis; with bacteria, notably the photosynthetic bacteria, Rhodospirillum rubrum and Rhodopseudomonas spheroides; and with carrot roots and homogenates, tomato fruit and homogenates, and algae and etiolated seedlings. Synthesis in vitro of carotenoids by the above...

The potential for lead (Pb) and arsenic (As) transfer into vegetables was studied on old orchard land contaminated by lead arsenate pesticides. Root (carrot), leafy (lettuce), and vegetable fruits (green bean, tomato) were grown on seven "miniplots" with soil concentrations ranging from near background to ≈ 800 and ≈ 200 mg kg-1 of total Pb and As, respectively. Each miniplot was divided into s...

The aim of the study was to evaluate the influence of various chemical forms of iodine (Iand IO3 -) and selenium (SeO3 2and SeO4 2-) on the nutritional and health-promoting quality of carrot (Daucus carota L.) storage roots. The experiment (conducted in 2012-2014) comprised the soil fertilization of carrot 'Kazan' F1 in the following combinations: 1. Control, 2. KI, 3. KIO3, 4. Na2SeO4, 5. Na2S...

A human intervention study with vegetable products has been performed in twenty three healthy, non smoking males aged 27-40. It was the aim of the study to assess whether consumption of vegetables containing different carotenoids could protect against DNA damage and oxidative DNA damage. The subjects consumed their normal diets, but abstained from vegetables high in carotenoids throughout the s...

Detection of group B Streptococcus (GBS) strains at various bacterial concentrations was evaluated using three pigment-producing broth media. At 10(3) CFU/ml, StrepB carrot broth (SBCB), Granada instant liquid biphasic (IGLB), and Northeast Laboratory GBS screening medium (NEL-GBS) showed 100% detection, but at the lower bacterial counts, SBCB and IGLB were more sensitive than NEL-GBS after 24 h.

Transformed root cultures of three nonmycotrophic and one mycotrophic plant species stimulated germination and hyphal growth of the vesicular-arbuscular mycorrhizal fungus Glomus etunicatum (Becker & Gerd.) in a gel medium. However, only roots of the mycotrophic species (carrot) supported continued hyphal exploration after 3 to 4 weeks and promoted appressoria formation by G. etunicatum.

to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...

The rate of incorporation of (14)C from acetate-1-(14)C into fatty acids by carrot root discs, 18 hours after inoculation with Ceratocystis fimbriata, was 9-fold greater than that in freshly cut discs. The rate in discs treated with water or Ethrel was 3-fold greater. The rate of incorporation of (14)C from glucose-U-(13)C into fatty acids was 3-fold greater 18 hours after any of the above trea...

in this study, production of fermented functional beverage based on the mixture of carrot, beet and apple juices using the lactobacillus casei was carried out. factors of consumption of reduction sugars, brix and bacterial growth were examined after fermentation and during the storage for 28 days and at 4˚c. to produce probiotic fermented mixture of carrot, beet and apple juices and lactobacill...
