摘要: Summary The accumulation of Chlide was investigated in flash-irradiated dark-grown plants as dependent on the decreased carotenoid content. Wheat ( Triticum aestivum L.) were treated with two concentrations (10 and 100 μmol/L) norflurazon (SAN-9789) during germination, which caused inhibition synthesis. When SAN-treated grown darkness amount accumulated protochlo-rophyllide increased. After an irradiation carotenoid-deficient etiolated increasing number flashes (1–6) decrease protochlorophyllide chlorophyllide faster comparison non-treated ones. flash phototransformation a greater originally molecules to chlorophyllide, that way Chl synthesis had been stopped could continue more efficiently.
