Interactive effect of simulated acid rain, calcium silicate, and γ-aminobutyric acid on physiological processes in corn and wheat

The effect of calcium silicate, γ-aminobutyric acid (GABA), and their mixture on the adaptation wheat corn to simulated rain has been evaluated in pot experiments. Acid was by watering twice with distilled water acidified sulfuric pH = 2. Test plants were grown a plant growth chamber under controlled conditions temperature, illumination relative humidity for 18 days. physiological state test assessed characteristics (shoot height, root length, dry weight shoots roots), content photosynthetic pigments, flavonoids, proline leaves. For corn, anthocyanins roots also evaluated. In parallel, physical chemical soil (pH, electrical conductivity, redox potential, soluble carbonates, nitrates) determined.It established that inhibited accumulation pigments leaves corn. protective metabolites (proline, anthocyanins) increased. Wheat showed greater sensitivity inhibiting acidification compared application CaSiO3 more effective than GABA restoring value HCO3- concentration soil, while effectively promoted NO3- anions soil. Combining most properties altered stimulating photosynthesis test-plants. Thus, is promising further studies possibility its mitigate negative impact depositions vegetation
