Nitrate accumulation is one of the main factors secondary soil salinization in protected horticulture China. Previous studies have shown that a low red(R)/far-red (FR) ratio can improve salt tolerance plants under NaCl stress. However, effect R/FR on plant growth nitrate stress not clear. In order to explore adaptability pakchoi high nitrogen stress, index, soluble protein content, sugar reduct...

Field experiment was carried out to study on the spatial and temporal distribution of soil nitrate nitrogen at Ranzhuang water resources experiment station in Hebei piedmont plain from 2011 to 2012. The results show that nitrate nitrogen content varies in sinusoidal curve at shallow tilth soil and shows in “W” shape at deep soil profile during the wheat-maize rotation period. Nitrate nitrogen i...

Diets rich in fruits and vegetables reduce risk of adverse cardiovascular events. However, the constituents responsible for this effect have not been well established. Lately, the attention has been brought to vegetables with high nitrate content with evidence that this might represent a source of vasoprotective nitric oxide. We hypothesized that short-term consumption of spinach, a vegetable h...

The influence of different nitrate concentrations in combination with three cultivation temperatures on the total fatty acids (TFA) and eicosapentaenoic acid (EPA) content of Nannochloropsis salina was investigated. This was done by virtue of turbidostatic controlled cultures. This control mode enables the cultivation of microalgae under defined conditions and, therefore, the influence of singl...

conclusions according to the results of the study, standard amount of nitrate in drinking water had no significant impact on laminin content. on the other hand, exceeded nitrate concentrations limited the distribution of laminin, leading to potential adverse effects on glomerular basement membrane. results in the study, intensity of reaction to anti-laminin was not the same in renal glomeruli. ...

Although temperature effects on phytoplankton growth and photosynthesis can be clearly demonstrated in the laboratory, their relevance in the field is much harder to establish. Recently, however, it has been recognized that temperature has a significant influence on nitrogen uptake. In particular, temperate marine diatom species may be limited by their ability to acquire nitrate at temperatures...

nitrate toxicosis associated with consumption of pigweed red-root (amaranthus retroflexus) wasdiagnosed in a small herd of cattle in the suburb of mashhad, northeastern iran. the clinical signs wereruminal tympany, incoordination, tachycardia, dyspnea, head pressing, aggressive movements and jugulardistension. seven animals including 3 young calves and 4 cows died of intoxication; other affecte...

-A three-compartment lettuce model designed to predict growth and nitrate concentration under severe nitrogen stress conditions is described and calibrated using data of N-limitation experiments. Since the limited amount of data does not allow calibration of all the model parameters, sensitivity analysis was used to determine which parameters should be estimated using this data. The calibrated ...
