Description:

The influence of surplus normál oř deficient nitrogen nutrition on the organization of maize chloroplast pigment apparatus was investigated. The amoímt of light- harvesting pigment-protein complexes (LHC) was the highest in chloroplasts fi^om high-nitrogen plants. Nitrogen deficiency resulted in a strong reduction of LHC, especially of its oligomer form. The fine structure of low temperature chloroplast absorption spectra revealed a relative decrease in the intensity of the 663, 666 and 678 nm components, while that of the components at 672 and 674 nm was increased. The changes in fine structure of the red fluorescence excitation spectra (F720 and F736) reflected similar changes in absorbance spectra. The changes do not allow to draw conclusions about the disturbance in energy transfer efficiency between some chlorophyll forms.
