칼슘과 마그네슘 처리가 민트(Mentha spp.)의 생육 및 무기성분 함량에 미치는 영향

Abstract

Studies on the specific nutritional requirements of Mentha spp. suitable to the climate of each country have been studied from a long time ago around the world. As a result, it was revealed that the change of the nutrient solution depending on the concentration of nitrogen(N), phosphorus(P) and potassium(K) affects the growth of Mentha spp. Therefore, the concentrations of nitrogen(N), phosphorus(P) and potassium(K) were fixed in this experiment and treated differently in the nutrient solution of calcium(Ca) and magnes ium(Mg). Peppermint(Mentha piperita L.), spearmint(Mentha spicata L.) and apple mint(Mentha suaveolens Ehrh.) were treated at 0.5me L-1, 1me L-1, 2me L-1, 4 me L-1 and 6me L-1 of calcium(Ca) and magnesium(Mg) nutrient solution, respectively. After 7 weeks of nutrient solution treatments, the morphological growth and mineral content of each plant were measured. Based on the mineral content of each plant, the contents of calcium(Ca)/magnesium(Mg), potassium(K)/magnesium(Mg) and potassium(K)/calcium(Ca) ratios was confirmed. The morphological growth conditions of peppermint(Mentha piperita L.) were the best in Ca 1me L-1 and Mg 0.5me L-1. Spearmint(Mentha spicata L.) showed the highest Ca 1me L-1, Mg 0.5me L-1 and Mg 6me L-1, respectively. Apple mint(Mentha suaveolens Ehrh.) were highest in Ca 1me L-1 and Mg 1me L-1. The Ca/Mg, K/Mg and K/Ca ratios of Mentha spp. were the best when Ca/Mg ratio was in the range of 1.33:1-1.62:1 except for peppermint(Mentha piperita L.) and spearmint(Mentha spicata L.) by magnesium(Mg) treatment.The K/Mg and K/Ca ratios were high in the range of 5.82:1-6.73:1 and 3.72:1-4.50:1, respectively. The calcium(Ca) content of the Mentha spp. with the best morphological growth state was 6640-11027μg g-1 and the content of magnesium(Mg) was within the range of 3717-8560μg g-1. As a result, the most suitable calcium(Ca) and magnesium(Mg) concentrations for morphological growth of Mentha spp. were Ca 1me L-1, Mg 0.5me L-1 and Mg 1me L-1.
