| 英文摘要 | The callus of medical plant Lycium barbarum L. in Ningxia was used as the materials for inducing somatic embryogenesis, and multitracer technique and gamma -ray energy spectrum analysis were used for studying the rates of uptake of several tracer metal ions during embryogenesis. The results were: 1) Of 23 radionuclides, only 16 (Mn-52, Zn-65, Co-56, Co-60, As-74, Se-75, mTc-95, Rh-99, V-48, Rb-83, Rb-84, Sr-85, Y-87, Y-88, Zr-88 and Zr-89) were selectively absorbed, the other 7 (Be-7, Tc-96, Ru-97, mRh-101, Sc-46, Ga-67 and Cr-51) were not absorbed. 2) The rates of absorption of different metal ions were different at the same developmental stage. In 10 day culture, the rates of uptake of most metal ions were 5%/g, but that of Se-75, Ab-83, Sr-85 and Zr-89 were 10% - 30%/g. The rates of absorption of the same metal ion were different at the same developmental stage, e.g. the rates of uptake of Se-75 were increasing in the course of development, two peaks of absorption appeared in the 5-7th and 15-20th days, being 14%/g and 20%/g. But, around 10th, the uptake rate decreased somewhat. The maximum uptake rate was 20%/g in 20th days. The uptake rates of some metal ions were with the sometimes keeping pace differentiation of embryonic cells, But sometimes not and division. The tendencies of the uptake rates of Se-75, Rb-83, Sr-85, Co-56 and V-48 were similar, indicating that the metal ions were accumulated in the callus during somatic embryogenesis. The uptake rate of Mn-52 was not only similar to other elements, but the variation was like normal distribution. |
