Abstract

Potassium (K) nutrition is very important for high yield and quality of litchi (Litchi chinensis Sonn.) fruits. However, overdose of fertilizer K, especially when the application ratio of fertilizer N:K2O is <1:1, can induce fruit cracking in litchi by reducing Ca concentrations in all parts of the fruit. Common abbreviations and notes: K = potassium; N = nitrogen; Ca = calcium; B = boron; Mg = magnesium; OT = ordinary (litchi) trees; KT = litchi trees that received excess potassium chloride (KCl).
