With the objective of determining the correlations among the quality of the orange fruit and the macronutrients, considering the balance among the nutrients through binary relationships; thirty orange trees (Citrus sinensis L. (Osb.) cv. 'Valencia' grafted on mandarin 'Cleopatra' were selected in a 20 year-old orchard, in the town of Nirgua, in Yaracuy state. In each plant were collected 12 samples of 12 fruits each and were determined: fresh mass, peel thickness, juice percentage, total titratable acidity (TTA), total soluble solids (TSS) and the ratio (TSS/TTA). Fifteen foliar samples were collected to determine the concentration of the essential elements. Later on, the binary relationships (that is to say: concentration of element A x concentration of element B, concentration of element A/concentration of element B; and concentration of element B/concentration of element A) among all macronutrients concentrations and with the rest of the elements were calculated. The Pearson correlation for quality variables and the macroelements concentration was evaluated, and also for quality variables and all binary relationships calculated. Alone two significant correlations was obtained among the macronutrients concentration and the variables of quality, which were between K and TSS, and between S and maturity index. Twenty-seven binary relationships were correlated with quality variables in significant or highly significant shape. The binary relationships explained the data quality variables better than macronutrients foliar concentrations |
