摘要
In studies of a parasite-host plant system, 5 pelargonium cultivars were used to test the influence of plant cultivars on concentration of mineral elements in parasite tissue - Cuscuta reflexa (dodder). Experiments were performed in a greenhouse where dodder parasitized different pelargonium cultivars for 60 days. Mineral analysis of all 5 cultivars showed that leaf N concentration was higher than in dodder, while stem concentration of N was lower than in dodder. Concentrations of P and K were higher in dodder tissue than in host plant. Concentrations of Ca and Mg were extremely reduced in dodder.
