The current study describes novel and quick methods for the quantification of K⁺ and Na⁺ in banana leaves using Horiba Laqua twin ion meters. Foliar K⁺ and Na⁺ content measured by ion meter significantly correlated with standard test values by coefficients of 0.83 and 0.46, respectively. About 48 absorbance values associated with potassium concentrations at wave numbers (1581 to 1583 and 3194 to 3410 cm⁻¹) and 15 sodium associated wave numbers (3773 to 3996 cm⁻¹) predicted potassium and sodium content with regression coefficients of 0.999 and 0.588, respectively. K⁺ and Na⁺ cations of fresh leaves in seven banana varieties were quantified using ion meters and new information of differences in the foliar potassium and sodium contents was found between banana varieties within the AAB group. The Rasbali (Silk subgroup) variety possessed greater potassium (5413 mg/L) and sodium (188 mg/L) ions than Amti (Mysore subgroup).

当前的研究描述了使用 Horiba Laqua 双离子计定量香蕉叶中K ⁺和 Na ⁺的新颖且快速的方法。离子计测得的叶面K ⁺和Na ^{+含量与标准测试值显着相关，系数分别为0.83和0.46。}大约48个与波数（1581至1583和3194至3410 cm ^-1）钾浓度相关的吸光度值和15个钠相关波数（3773至3996 cm ^-1）预测钾和钠含量，回归系数为0.999和0.588，分别。使用离子计对七个香蕉品种的新鲜叶子的K ⁺和 Na ^{+阳离子进行了定量，并发现了 AAB 组内香蕉品种之间叶面钾和钠含量差异的新信息。}Rasbali（丝绸亚群）品种比 Amti（迈索尔亚群）拥有更多的钾离子（5413 毫克/升）和钠离子（188 毫克/升）。
