To understand how sulfur nutrition affects the quality and yield of vegetable plants, we have grown two cultivars of pakchoi (Brassica campestris L. ssp. chinensis var. communis cv. Shang Hai Qing and You Dong Er) hydroponically in nutrient solution supplied with two levels of sulfur (0.0558 mM as sulfur deficiency and 1.0058 mM as sulfur sufficiency, respectively) for three weeks and their growth, nutrient uptake and glucosinolate content under these two sulfur conditions were investigated. The results showed that plant growth of both the cultivars was inhibited by sulfur deficiency. The concentrations of nitrogen and magnesium in shoots of both the cultivars were increased notably under sulfur deficiency, but there was no significant change in concentrations of sulfur, potassium and calcium. Moreover, sulfur deficiency increased phosphorus uptake in You Dong Er but not in Shang Hai Qing. In Shang Hai Qing sulfur deficiency reduced the content of all individual and total glucosinolates, while in You Dong Er this was also the case for most individual and total glucosinolates. However, in You Dong Er the total aliphatic glucosinolate concentration was not significantly influenced but the concentrations of individual aliphatic glucosinolates-glucoalyssin and gluconapin were in contrast increased under sulfur deficiency. Our data show that sulfur deficiency will decrease the yield and deteriorate the quality of pakchoi vegetable by reducing its growth and the contents of nutrients and glucosinolates. In addition, there was a significant genotypic variation in the composition and content of glucosinolates between these two pakchoi cultivars when exposed to sulfur deficiency.

Inhibition effect of Schiff base namely 1-(2-hydroxybenzylidene)-3-(2,5-dioxoimidazolidin-4-yl) urea(ALS) was studied on carbon steel corrosion in 1.0 M HCl by using the electrochemical impedancespectroscopy (EIS), potentiodynamic polarization and linear polarization (LPR) and quantum chemicalstudy. The values of activation energy (Ea), equilibrium constant (Kads), adsorption free energy DG8ads,adsorption enthalpy DH8ads and adsorption entropy DS8ads were discussed. The adsorption of inhibitor onmetal followed Langmuir’s adsorption isotherm. The thermodynamic parameters of adsorption revealthat there is a strong interaction between inhibitor and carbon steel. The highest inhibition efficiencywas observed 5.0 10 4 M ALS concentration at 318 K. SEM and EDX observations confirmed theexistence of protective inhibitor film on metal surface. Quantum chemical study supports thecomparative inhibition effect of ALS.
