Plants were grown in a growth chamber (25°C/18°C day/night) with a 12-h photoperiod. Sap was collected from petioles of young-mature (nos. 7 and 8) and old (no. 1) leaves 5 weeks after the inoculation of cotyledons. Five plants were used for each treatment. Values followed by the same letter within a column are not statistically different at the 5% level.
