| Popis: | The introduction of fluorescence microscopy in the 1920s opened up the practical investigation of chlorophyll fluorescence. Ву microscopic study of thin sections it was shown that all photosynthetic tissues emitted red fluorescence when exposed to UV-A or blue light. Kautsky and Hirsch [13] were the first to report the pattern of fluorescence induction when dark-adapted leaves were exposed to light. It was assumed that the kinetics of fluorescence emission during induction reflected the initial phases of the induction of photosynthesis. Later research has proved this assumption correct and chlorophyll fluorescence is today used as a sensitive, in vivo probe of photosynthetic function, both in the field and in the laboratory. Today, new instruments provide ready means for the measurement of chlorophyll fluorescence in vivo. However, data must be interpreted with caution. |
