Why is phloem sap alkaline & xylem sap acidic? Please explain.

The literature provides little data about the pH of phloem sap. However, it was believed that phloem sap is moderately alkaline (7.3–8.5) and the acidic pH values reported in the past was likely due to contamination with xylem exudates and bark tissue
