Effect of selenium foliar application on chicory (Cichorium intybus L.).
Leaves of young chicory (Cichorium intybus L.) plants were sprayed with selenate (1 mg SeVI/L) to establish the distribution of added selenium (Se) in the heads. Its concentration was analyzed in the outer, intermediate, and innermost leaves of chicory heads. The concentration of Se was about double (43-46 ng Se g-1 DM) that in the control (21-24 ng Se g-1 DM), indicating that the applied Se was transported from the sprayed leaves to the heads. In cv. Monivip, Se concentration was even throughout the head, but in cv. Anivip, the innermost leaves had a lower concentration of Se. No visual symptoms of Se toxicity appeared on the plants, and the quantum yield of photosystem II showed no indication that Se spraying could be harmful for energy conversion. Se increased the respiratory potential in young plants but not in plants at harvest time.
