The crop Water Footprint (WF) can provide a comprehensive knowledge of the use of water through the demarcation of the amount of the water consumed by different crops. The WF has three components: green (WFg), blue (WFb) and grey (WFgr) water footprints. The WFg refers to the rainwater stored in the root zone soil layer and is mainly utilized for agricultural, horticultural and forestry product...

The influence of copper sulphate on the regeneration of carrot (Daucus carota L.) androgenic embryos and changes in the levels of phenolic substances and polyamines that might be indicative of the response to oxidative stress were investigated. The cultivation on the regeneration medium supplemented with Cu(2+) at the concentrations 1 and 10 microM for 15 weeks resulted in significant dose-depe...

background: selling unpasteurized fruit juices is common in iran. since health standards are not met in preparation and distribution of these products, food infections may increase. the objective of this study was to assess microbial contamination of handmade fruit juices in gorgan, iran. methods: this cross-sectional study was conducted in the first half of 2009. overall, 100 carrot and cantal...

ABSTRACT: One of the biggest challenges in intercropping two or more crops is to maintain their productivity as that sole counterparts. In order obtain sustainable systems a semi-arid environment, this study evaluated agro-economic advantage and sustainability intercropped carrot cowpea, optimizing green manuring spatial arrangements. Experiments were conducted period from July October 2017 201...

Monitoring tools for detecting the presence of fungus gnats (Bradysia spp.) are a critical part of effective IPM programs for these pests in greenhouse production systems. Research has demonstrated the effectiveness of yellow sticky cards for monitoring adult fungus gnats; similarly, potato disks placed on the surface of the growing media in pots have been shown to be effective monitoring tools...

The expanding production and use of engineered nanomaterials (ENMs) have raised concerns about the potential risk of those materials to food safety and human health. In a prior study, the accumulation of Zn, Cu, and Ce from ZnO, CuO, or CeO2, respectively, was examined in carrot (Daucus carota L.) grown in sand culture in comparison to accumulation from exposure to equivalent concentrations of ...

The respiration of carrot (Daucus carota L.) roots is stimulated by ethylene. Polyribosomes were shown to proliferate concomitantly with the increase in respiration, and the extent of polyribosome augmentation was closely correlated to the amount of respiratory stimulation. In addition to the increase in quantity, ethylene caused a 2-fold increase in the average polyribosome size, suggesting ti...

Polyclonal antibodies able to recognize protein-acetaldehyde conjugates were produced and characterized. The antibodies react with sodium cyanoborohydride-reduced Schiff's bases between acetaldehyde and a protein, independently of the nature of the macromolecule binding the acetaldehyde moiety. Only conjugates between acetaldehyde or propionaldehyde and a protein are recognized; conjugates obta...

A modified assay for inhibition of ice recrystallization which allows unequivocal identification of activity in plant extracts is described. Using this assay a novel, cold-induced, 36 kDa antifreeze protein has been isolated from the tap root of cold-acclimated carrot (Daucus carota) plants. This protein inhibits the recrystallization of ice and exhibits thermal-hysteresis activity. The polypep...
