- 要約等Measurements of photosynthetic photon flux (PPF) were mad......various radiation sources in eleven different controlled environment facilities......ally available photon-flux sensors and companion meters. Calibration of the sensors was checked by the National Bureau of Standards with......ent lamps. Readings from the two lamps agreed for each sensor/meter set within 1 to 2%. Measurements made with the two sensor/meter sets by investigators in each of the laboratories s......ment (SD= ±1%) in the relative output of the two sensors under a given ......amp type, even in different types of plant growth chambers. The two sensor outputs differed s...
