Since climate changes have caused water restrictions, safflower stands out as an alternative crop due to its adaptability restrictive soil and conditions. Thus, this research aimed evaluate the physiological yield performance of four lines (IMA 02, IMA 04, 14, 21) under two regimes [without deficiency—around 22% moisture content—100% field capacity (FC); with deficiency—50% FC]. The were impose...

OBJECTIVE To determine the magnitude of goitre in school children and measure indicators of iodine deficiency including the most commonly consumed staple foods. DESIGN A cross-sectional study. SETTING Ten villages from four administrative regions of Ethiopia. SUBJECTS A total of 2485 randomly selected elementary school children were examined for clinical signs of goitre. Indicators of iod...

BACKGROUND AND AIMS Crassulacean acid metabolism (CAM) is currently viewed as an adaptation to water deficit. In plants of Clusia minor, which grow mostly on acidic, P-deficient soils, CAM is induced by water deficit. The symbiosis between plants and mycorrhizal fungi alleviates the symptoms of P deficiency and may influence drought resistance. Therefore, the effect of P supply, modified by thr...

dieback of trees is a serious problem in many different regions of the world and city authorities are concern about conserving and maintaining the green spaces in the big cites. this study was conducted to evaluate the early dieback and yellowing of sycamore trees (platanus sp.) by using a completely randomized block design (split split plot) in 15 replications (sites) in 2009. the main plot wa...

The effect of boron (B) deficiency on cell permeability and connected with that, changes in soluble sugars, amino acids and ureides partitioning between root and nodule apoplast and symplast of N2 fixing soybean plants grown in water culture were studied. Exposure of a transient 10 -day B deficiency stress was found to inhibit nodule number and to increase nodule dry weight. The formation of la...

Elevated CO2 (eCO2) increase plant biomass and might lead to nutritional losses. The results showed that eCO2 under Fe-deficiency stimulates root dry weight from 0.37–0.80 g plant?1 shoot 0.82–2.10 plant?1, without compromising root/shoot ratio. Besides, improved the chlorophyl content of Fe-deficient plants. However, downregulation photosynthesis, reduction in stomatal conductance transpiratio...

Using an animal model of Wernicke-Korsakoff syndrome, in which rats were submitted to a chronic ethanol treatment with or without a thiamine deficiency episode, the glutamate uptake in the prefrontal cortex and spatial memory aspects were studied. It was found that (i) thiamine deficiency, but not chronic ethanol consumption, induced a significant decrease of glutamate uptake; (ii) thiamine-def...
