Abstract

This paper represents our efforts to diagnose environmental stresses using physiological instruments in cucumber plants. The stresses could be detected by measuring and analyzing the difference of chlorophyll content, photosynthetic efficiency(Fv/Fm), differential temperature(DT), stomatal resistance and light absorbance values between treated and controlled plants. From the all over experiments, the stresses could be first diagnosed on the 1st to 5th day after treatment and the overall diagnosis rate was estimated at more than 50%.
