CHLOROPHYLL FLUORESCENCE KINETICS AS A MEASURE OF STRESS IN PLANTS INFESTED WITH APHIDS: IMPLICATIONS FOR STUDIES OF RESISTANCE

Fluorosensing of water stress in plants:

We modified a PAM fluorimeter for remote detection from 0.5 m to 1 m distance by using a laser diode for excitation. It permitted us to compare directly and simultaneously measurements of relative fluorescence yield to the measurements of lifetinae with the r-LIDAR performed under natural conditions
