Abstract
Research was conducted to establish the leaf and petiole sap test to diagnose the nutritional status of tomato. The concentrations of $NO_3$, $PO_4$, K, Ca, Mg and $SO_4$ ions extracted from the leaves and petioles in the different positions in a plant were measured and compared with their corresponding inorganic contents in the leaves analyzed by the chemical method. The ionic concentrations in the leaf and petiole sap showed the different values depending on their positions in a plant. The leaves and petioles in the lower positions of a plant had higher concentrations of $NO_3$, Ca, Mg and $SO_4$ ions. In particular, there were greater changes of ionic concentrations and less increases in the leaf length and width from the 9th compound leaf down from the uppermost cluster. On the other hand, the leaflets in a compound leaf had the same ionic concentrations. Therefore, it appeared that the optimal sampling position of leaf and petiole for the sap test is the leaflets of the 9th compound leaf down from the uppermost cluster. A good correlation between the sap test and the chemical analysis of plant showed that the ionic concentrations in the leaf and petiole sap reflect the nutritional status of tomatoes.
