Resumo
The impact that the parasitic plant field dodder (Cuscuta campestris Yunk.) has on chlorophyll fluorescence and chlorophyll content of infested alfalfa (Medicago sativa L.) and sugar beet (Beta vulgaris L.) was examined under controlled conditions. Several parameters of chlorophyll fluorescence were measured in infested and non-infested alfalfa and sugar beet plants over a period of twenty days, beginning with the day of infestation. Chlorophyll contents (total, relative and ratio of chlorophyll a to b) were determined 1, 7, 14 and 20 days after infestation (DAI). Field dodder was found to affect both the total and relative chlorophyll contents in infested alfalfa and sugar beet, causing significant reduction in chlorophyll content in both host plants. This parasitic plant also affects a number of parameters of chlorophyll fluorescence (Fo, Fv/Fm, ΦPSII, Fv and IF), showing that these parameters may be considered sensitive indicators of the impact that field dodder has on its host plants.
