英文摘要The distribution pattern of La, Ce, Nd, Tb, Dy was in the order as leaf > root > stem, that of Pr, Sm, Eu, Gd, Ho, Y was as root > leaf > stem in fern Dicranopteris dichotoma Underw. Light and moderately heavy rare earth elements were easily selectively absorbed and then accumulated by the fern D. dichotoma. Many mainly light rare earth elements are bound to chlorophyll in D. dichotoma. Among the 15 detectable rare earth elements binding to chlorophyll, lanthanum content (50.08%) was the highest, and cerium content (19.40%) is the second of all. FXAFS (Fluorescence X-ray absorption fine structure) spectral analysis revealed that lanthanum coordinated 2 porphyrin rings and La-chlorophyll-a may have bilayer structure in D. dichotoma.
