1. PSI FluorPen FP 100 with detachable leaf clips
Portable, battery-powered PAM fluorometer that enables quick and precise measurement of chlorophyll fluorescence parameters in the laboratory, greenhouse, or in the field. It can be effectively used for studying photosynthetic activity, stress detection, herbicide testing, or mutant screening.
Rapid and accurate measurement of photosynthetic parameters.
– Photosynthetically Active Radiation measurements
– Leaf-clips for dark adaptation
– Fast chlorophyll fluorescence induction kinetics measurements
– Lab and field applications
Measured parameter:
Ft – Instantaneous Chlorophyll Fluorescence
Ft is equivalent to Fo if the leaf sample is dark-adapted.
QY – Quantum Yield
QY is a measure of the Photosystem II efficiency. In a dark-adapted leaf this is equivalent to Fv/Fm. In a light-adapted leaf it is equivalent to Fv’/Fm’.
NPQ – Non-Photochemical Quenching
The NPQ protocol is the most typically used measuring approach to quantify photochemical and non- photochemical quenching. The measurement should be performed with a dark-adapted sample (see more in Chapter 8.E. of this Manual).
OJIP – Chlorophyll Fluorescence Induction Kinetics
The OJIP curves enable observing major changes that occur during exposure of plants to high irradiance (see more in Chapter 8.D. of this Manual).
Light Curve
The LC 1 and LC 2 protocols serve to describe adaptation of Quantum Yield to six or five different light levels (see more in Chapter 8.F. of this Manual).
