Diagnosis and correction of iron chlorosis in fruit trees: A review

摘要: Several plant species grown in calcareous soils arid and semiarid regions are iron-deficient, a condition known as limeinduced iron chlorosis, or simply chlorosis. The nutritional status of perennial plants is commonly evaluated by leaf analysis. However, there often no correlation between leaves degree therefore analysis presents serious limitations technique to evaluate lime-induced Recently, for the early prognosis chlorosis based on floral was developed fruit trees help prevent development deficiency avoid losses yield quality. Correction carried out massive applications synthetic chelates soils. Since rapidly immobilised soil, this treatment has be repeated each year, representing major part fertilizer costs. Environmental impacts have not been properly investigated, but it that they also result enhanced uptake metals such copper nickel. Alternative, more environment-friendly treatments being evaluated. In article we concentrate reviewing current methods detect correct trees.
