Low Temperature Fluorescence Spectra of Chloroplasts: Methodical Aspects and Possible Applicationswer and higher, better distinguishable bands, and the possibility to study rapid changes in the structure of photosynthetic apparatus. The sample for measuring correct fluorescence spectra must not contain a large amount of pigments (only pale thin leaves or chloroplast preparations are appropriate)

Steady State Photosynthesis in Intact Plants as Analyzed by Chlorophyll Fluorescence and Far-Red Specopy) to electron transport during steady state assimilation. From the data we derived expressions which provide a basis of conducting measurements of the apparent guantum yield and the rate of photosynthesis non-inva-sively and remotely, using optical approaches which do not reguire the enclosure o

Complete Fluorescence Emission Spectra Determined During the Induction Kinetic Using a Diode-Array Dg the fast rise and the slow decline of the Kautsky induction kinetic. Thus fast spectral changes in the millisecond range can be detected. Changes in pigment-protein complexes during the first seconds of illumination of an etiolated leaf can be measured at room temperature. During the Kautsky induc

Changes in Chloroplast Fluorescence during Leaf Developmentindividual pigment-protein complexes that have various functions in the photochemistry of photosynthesis. The ontogenic differences in composition of the set of pigment-protein complexes are reflected in spectral properties of chloroplasts and leaves. Changes in shapes of fluorescence emission and e

Measurement and Analysis of Chlorophyll Fluorescence in Plants Using Modulated Actinic Illuminationght modulated in intensity using a voltage controlled lightsource. The actinic light was sinusoidally modulated in the frequency range from 0.02 to 100 Hz. The observed chlorophyll fluorescence changes are a more or less linear function of the actinic light intensity at modulation frequencies above

Measurement of the Laser-Induced Chlorophyll Fluorescence Kinetics Using a Fast Acoustooptic Devicetwo different wavelengths (690 and 730 nm regions) excited by a HeNe-laser. The exciting laser beam is controlled by a fast acoustooptic device. The rising time of the illumination is shorter than 200 ns. The data acquisition rate of the LICAF is at maximum 2000 data/sec, at each of the two waveleng

Temperature Dependence of in Vivo Chlorophyll Fluorescence as Affected by DCMUboth species two abrupt changes occurred in the maximal variable chlorophyll fluorescence plotted against temperature. Cucumber showed breaks around 20°C and 9°C and tomato around 24°C and 15°C. In the presence of DCMU, which blocks electron transport, the low temperature breakpoint disappeared; the
