Water relations, pigment stabilization, photosynthetic abilities and growth improvement in salt stressed rice plants treated with exogenous potassium nitrate application
Potassium is a major nutrient which may play an important role in many processes such as ion homeostasis in plant cells and osmotic adjustment of guard cells during stomatal opening and closing. Pathumthani 1 (PT1) rice has been reported as being a salt sensitive cultivar and has been selected as a model plant in this study to investigate the possibility of improving the osmotic potential, pigm...
متن کاملThermodynamics of the solubility of potassium nitrate in the mixed solvent, Ethanol+Water, and the related Ion-association
Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...
متن کاملNitrate reductase for nitrate analysis in water
Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase. The key to applying this Green Chemistry solution for nitrate analysis is plentiful, inexpensive, analytical grade enzyme. We demonstrate tha...
متن کاملTheoretical study of ferroelectric potassium nitrate
We present a detailed study of the structural behavior and polarization reversal mechanism in phase III of KNO3, an unusual ferroelectric material in which the nitrate groups rotate during polarization reversal. This material was one of several studied in a previous work O. Diéguez and D. Vanderbilt, Phys. Rev. Lett. 96, 056401 2006 where methods were described for computing curves of energy ve...
متن کاملNitrate interference with potassium-selective microelectrodes
tions of K+, and triple-barrelled microelectrodes measuring K pH and membrane potential m have provided Initial attempts to measure K+ activity (a K ) in vacuoles a major advance towards this goal ( Walker et al., 1995, of barley leaf epidermal cells using triple-barrelled K+1996). The incorporation of a pH-sensing barrel allows selective microelectrodes gave values that were only unequivocal a...
