Geographic and Seasonal Variation in the Moisture Content of Scotch Pine Foliage

This study was suggested by observations of the moisture contents of foliage of live trees made for studies relating to the freshness of cut Christmas trees. Live trees were sampled in a planting of non-yellowing commercial strains on heavy silt loam near Urbana in central Illinois and a NC-51 provenance test on light sandy loam in Sinnissippi Forest in northern Illinois in December, 1968, and monthly during the fall of 1969.
