Plant shading increases lipid peroxidation and intensifies senescence-induced changes in photosynthesis and activities of ascorbate peroxidase and glutathione reductase in wheat.

Original language description

Plants of spring wheat (Triticum aestivum L. cv. Saxana) were grown during the autumn. Over the growth phase of three leaves (37 d after sowing), some of the plants were shaded and the plants were grown at 100 (control without shading), 70, and 40 % photosynthetically active radiation. Over 12 d, chlorophyll (Chl) and total protein (TP) contents, rate of CO2 assimilation (PN), maximal efficiency of photosystem 2 photochemistry (FV/FP), level of lipid peroxidation, and activities of antioxidative enzymesascorbate peroxidase (APX) and glutathione reductase (GR) were followed in the 1st, 2nd, and 3rd leaves (counted according to their emergence). In un-shaded plants, the Chl and TP contents, PN, and FV/FP decreased during plant ageing. Further, lipid peroxidation increased, while the APX and GR activities related to the fresh mass (FM) decreased. The APX activity related to the TP content increased in the 3rd leaves. The plant shading accelerated senescence including the increase in lipi

Stínění listů pšenice zvyšuje peroxidaci lipidů a zesiluje změny ve fotosyntéze a aktivity askorbát peroxidázy a glutation reduktázy způsobené senescencí.

Czech description

Na listech pšenice jarní stíněných porostem jsme studovali změny ve fotosyntéze a aktivitách některých entymů. Bylo zjištěno, že stiění listů zvyšuje peroxidaci lipidů a zesiluje změny ve fotosyntéze a aktivity askorbát peroxidázy a glutation reduktázy.
