What is Chlorophyll fluorescence quenching, zeaxanthin formation and light scattering in intact leaves of triazine-resistant and triazine-susceptible Chenopodium album plants about?
The triazinc-resistant biotype of Chenopodiura album has an impalt~i activity of photosystem H. In vivo, this leads to a higher sensitivity to photoinhibition, especially when the plants have been grown at a high irradiance. The activities of several protecting energy dissipation pathways were compared in triazine-resistant and triazine-susceptible biotypos which were grown at low and high irrediances. It was found that the resistant plants have more light-induced zeaxanthin formation and a larger change in light scattering than does the susceptible biotype. The differences were more pronounced when the plants were grown at a high itradiance. Stern-Volmer plots indicated that high light-grown plants show a linear relationship between non-photnehemical quenching qN and zeaxanthin content, and also between qN and change in light scattering. In low light-grown plants, the zeaxanthin content and the change in light scattering are not linearly related to qN and there is a strong increase in the value of qN already at low levels of zeaxanthin content and change in light scattering. The latter effect is smaller in the resistant biotype. Photoresplration is foond to be more important as an
