| Abstract:
For practical application of plant fluorescence measurement as a plant monitoring method, time required for measurement should be minimized. If measurement is conducted at night, one minute measurement per one point will be within an acceptable range. Another problem in applying this method in plant production settings is the spatial variations of the fluorescence characteristics within a plant. To elucidate spatial variations, one minute fluorescence measurment was conducted at ten different points within Rhododendron pulchrum. The spectra and fluorescence induction kinetics within one minute reflected the light environment each leaf has experienced. | |
