A Note on SAP pH in Eastern Redcedar (Juniperus Virginiana L.)

Bruce E. Cutter, Richard P. Guyette

Abstract


Twelve eastern redcedar (Juniperus virginiana L.) trees were sampled for the sap pH of the sapwood at three locations along the bole and one location on the roots. Soil pH measurements were taken at each tree site for comparison with sap pH. Sap pH was positively correlated with soil pH. A regression model using mean soil pH as the independent variable accounted for 71% of the variation of the mean sap pH. There was a decreasing gradient in sap pH from crown to stump.
