Blue (F450) and green (F530) leaf fluorescence were studied together with the red chlorophyll fluorescence (emission maxima F690 and F735) during light-induced chlorophyll fluorescence induction kinetics (Kautsky effect) in predarkened leaves of wheat (Triticum aestivum L.) and soybean (Glycine max L.). The intensity of the red chlorophyll fluorescence decreased from maximum fluorescence Fm to steady-state fluorescence Fs, and the fluorescence ratio F690/F735 decreased by about 10% from Fm to Fs. However, blue and green fluorescence intensities remained constant throughout the measuring time. Consequently, the ratio of blue to red fluorescence (F450/F690) increased during chlorophyll fluorescence induction kinetics, whereas the ratio of blue to green fluorescence (F450/F530) remained unchanged within the same period. The knowledge of these ratios will be a prerequisite for the interpretation of remote sensing data from terrestrial vegetation.
在小麦(Triticum aestivum L.)和大豆(Glycine max L.)的暗适应叶片光诱导叶绿素荧光诱导动力学(考茨基效应)过程中,研究了蓝色(F450)和绿色(F530)叶片荧光以及红色叶绿素荧光(发射最大值F690和F735)。红色叶绿素荧光强度从最大荧光Fm下降到稳态荧光Fs,荧光比率F690/F735从Fm到Fs下降了约10%。然而,在整个测量时间内,蓝色和绿色荧光强度保持恒定。因此,在叶绿素荧光诱导动力学过程中,蓝色与红色荧光的比率(F450/F690)增加,而在同一时期内蓝色与绿色荧光的比率(F450/F530)保持不变。了解这些比率将是解释陆地植被遥感数据的先决条件。
