Increasing the nitrate (N) concentration in the rooting substrate above deficiency decreased stomatal conductance and leaf growth rate compared with sufficient N in maize seedlings (Zea mays L.) growing in drying substrate. Novel effects were detected when N in the non-deficient range was supplied directly to the xylem of detached shoots: concentrations above 2.0 mol m-3 KNO3 reduced transpirat...

“Salting out effect” means that the addition of an organic solvent to an aqueous solution of a salt will reduce the solubility of salts and thus induce its precipitation.1 Therefore, the investigations of the physicochemical properties of inorganic salts in organic solvents – water, such as solubility data together with density, refractive index and so on, are of great scientific importance. Va...

We recently reported the first multiple oxygen isotope composition of nitrate (NO3 ̄) in ice cores. Post-depositional photolysis and volatilization may alter the isotopic signatures of snowpack nitrate. Therefore, the precise assessment of the geochemical/atmospheric significance of O-isotopic signatures requires information on the relative rates of photolysis (λ > 300 nm) of NO3, NO2O ̄ and NO2O...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...

The objective of this study was to evaluate the ability foliar application potassium nitrate (KNO3) induce water deficit tolerance in sorghum plants (Sorghum bicolor cv. P898012) subjected at pre-flowering. experiment conducted under greenhouse conditions with 4 treatments: field capacity (FC), (WD), + KNO3 (FC KNO3), and (WD KNO3). Two applications 3% (m/v) were made, first on day zero stress ...

Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...
