| 英文摘要 | Uptake, translocation, and distribution of C-14-labelled oligosaccharides in watermelon seedling were investigated by the means of radioactive isotope tracer. The autoradiograph experiment showed that oligosaccharides could fast be absorbed by the watermelon seedling after it was supplied through leaf or root. The translocation of the oligosaccharides in leaf trended from the margin to the center. After treatment by leaf-dripping for 8 h and treatment by root-dipping for 24 h, the oligosaccharides translocated and distributed in whole watermelon seedling, indicating that C-14-labelled oligosaccharides have a strong ability to spread and translocate downwards or upwards in the seedling. During 4 h to 120 h after the treatment by leaf-dripping, the specific activity of root, others (stem and indirectly treated leaf in the whole seedling) transformed from 0. 18X10(5) and 23. 08X 10(5)Bq/kg to 0.32X10(5) and 3. 02X 10(5) Bq/kg, respectively. As a whole, the trend of distribution and downward translocation was weak. During 4 h to 120 h after the treatment by root-dipping, the specific activity of root, stem, cotyledon, and true leaf transformed from 22. 23X 10(5), 2. 23X 10(5), 8. 33X 10(5) and 12. 78X 10(5) Bq/kg to 431. 11 X 10(5), 42-23X 10(5), 65. 57 X 10(5) and 7 8. 8 9 X 10(5) Bq/kg, respectively, suggesting a strong accumulation trend above the ground and upward translocation activity of C-14-oligosaccharides in watermelon seedling. |
