Research Abstract |
The electro-kinetic treatment enforces a slight decrease in viscosity to ease the absorption of ions and water by plant roots. After treatment many positive charges were generated near the surface of the ceramics. Cations incorporated with these positive charges are easily absorbed by the negative surface of the root. As a result, different growth parameters in Komatsuna plants have been improved. An increase in free amino acid contents in the leaves was also observed. So this treatment system can contribute to the stability of the growing high-quality vegetables in a short period of time.
