| Description
| - In tobacco leaves inoculated with TMV, changes in chlorophyll and carotenoid contents, parameters of slow Chl fluorescence kinetics, i.e. the maximum quantum yield of photosystem 2 (PS2) photochemistry Fv/Fm, the effective quantum yield of photochemical energy conversion in PS2 ?2, ratio of quantum yields of photochemical and concurrent non-photochemical processes in PS2 Fv/F0, non-photochemical quenching (NPQ), and photochemical activities of isolated chloroplasts were investigated. The Chl and carotenoid contents in infected leaves decreased with a progression of infection and were lowest in LGI. The ratio of Chl a/b declined similarly. The maximum quantum yield of PS2 photochemistry Fv/Fm, was decreased in the following order: first stage, DGI, and LGI. The same is true for the ratio Fv/F0. The decrease of ?2 in infected leaves declined as compared to their controls. On the contrary, NPQ increased in infected leaves, the highest value was found in the first infection stage. Photo...

- Studovali jsme změny v koncentraci chlorofylu a karotenoidů, parametry pomalé indukce fluorescence Chl a to: maximální kvantový výtěžek fotochemie fotosystému 2 (PS 2) Fv/Fm, efektivní kvantový výtěžek přeměny fotochemické energie v PS 2 ?2, poměr kvantových výtěžků fotochemických a nefotochemických procesů v PS 2 Fv/F0, nefotochemické zhášení (NPQ) a fotochemické aktivity isolovaných chloroplastů z tabákových listů infikovaných TMV. Obsah chlorofylu i karotenoidů poklesl v během postupu infekce, byl nejnižší v LGI ve druhém stádiu. Podobně poklesl i poměr chl a/b. Maximální kvantový výtěžek fotochemie PS 2 Fv/Fm se snižoval v pořadí: první stadium, DGI, LGI. Totéž jsme nalezli i u Fv/F0. Snížení ?2 v infikovaných listech se zmenšovalo proti jejich kontrolám. Naproti tomu NPQ v infikovaných listech vzrůstalo a nejvyšší hodnoty dosahovalo v prvním stádiu infekce. Fotochemické aktivity celého elektrontransportního řetězce v chloroplastech významně poklesly při postupu symptomů, nejn... (cs)
