Growth of Radish Sprouts Cultivated in Electrolyzed and Non-Electrolyzed Solutions with Different Strengths

摘要

This study was conducted to determine the effects of electrolyzed solution alkaline solution and mixed solution, mixed with the same volume of alkaline and acid solution and-non-electrolyzed solution KC1 solution, with different strengths, on thegrowth of radish Raphanus sativus L. sprouts, The electrolyzed solution was generated by dissolving KC1, as an electrolyte. The 1/1 247 mg L-1 of K+ concentration and 1/2 124 mg L-1 of K+ concentration strength alkaline solutions promoted the plantgrowth. Among the 1/1 strength solutions, the plant growth was most superior in alkaline solution, followed by mixed solution 176 mg L-1 of K+ concentration, and less superior in KC1 solution 175 mg L-1 of K+ concentration. One of the reasons of theaccelerated plant growth in 1/1 strength alkaline solution may be due to higher K+ concentration in the solution, because K+ acts as a fertilizer, However, in spite of the K+ concentration in 1/2 strength alkaline solution was lower than that in 1/1 strength mixed and KC1 solutions, the plant growth was more promoted in 1/2 strength alkaline solution. Therefore, the superior plant growth in alkaline solutions may concern not only K+ concentration but another factors, for example, lower oxidation-reduction potential ORP in the solution and/or easiness of mineral absoption by electrolysis.
