Exogenous Application of Mg, Zn and B Influences Phyto-Nutritional Composition of Leaves and Fruits of Loquat (Eriobotrya japonica Lindl.)

This study was conducted to analyze the effect of magnesium (Mg), zinc (Zn) and boron (B) on level macronutrients (Na, Mg, K, Ca), micronutrients (Zn, B, Mo, Mn, Fe, Co, Ni, Cu), heavy metals (Cd, As, Hg, Pb) in loquat leaves fruit tissues (peel, pulp, seed) using inductively coupled plasma-mass spectrometry (ICP-MS). Fruits were obtained from a orchard located Fujian (Yun Xiao/Zhangzhou). The results revealed that foliar application Mg increased concentrations Ca, Zn, Cu leaves; Mn pulp; Na, seeds. Zinc Co Ni peel; Na K Similarly, B Ca Overall, mineral detected loquats greatly influenced by Zn B. Although metal pulp fruits under safe limits for human consumption.
