| This study was carried out to investigate the effect of magnesium concentrations in fertilizer solution on growth and cut flower quality of chrysanthemum 'Biarritz'. The nutrient concentrations in plant tissue and soil solution of root media were also determined. Magnesium deficiency appeared on older leaves with interveinal yellow-green chlorosis. Marginal chlorosis and necrosis also developed on some of older leaves. Elevation of Mg concentration in fertilizer solution increased cut flower weight at harvesting stage resulting in the 8.84g in 1.5mM treatment. Dry weight of whole above ground plant tissue increased as Mg concentrations in fertilizer solution were elevated within the range from 0 to 15mM, but that of 20mM decreased compared to 15mM treatment. The dry weight of 0.5, 1.0 and 1.5mM treatments were 8.42, 8.75 and 8.848 and tissue Mg contents of those based on the youngest fully expanded leaves at harvesting stage were 0.34, 0.53 and $0.71%$, respectively. Based on dry weight and tissue Mg contents, Mg fertilization to maintain tissue contents higher than $0.64%$ is necessary to ensure flower quality and yield. By considering the concentration in 15mM treatment, Mg concentration in soil solution of root media should be higher than $3.68mg{cdot}L^{-1}$ at harvesting stage. |
