The relation between xylem pressure potential (P) and apparent photosynthesis (AP) was studied by reducing soil m.c. monthly from June to Oct. The effect on AP of soil temp. between 1 deg C and 45 deg C and of freezing was also studied, mainly in fir. The boundary lines of the relation between P and AP changed monthly as needles matured.
