摘要: When the primary leaf of a soybean plant was allowed to carry on photosynthesis in C14O2, small amount labelled carbon translocated downward into root at velocity least 5040 cm per hour. This 50 times greater than which sucrose phloem. The rapidly C14 not moved as dioxide. time translocation increased from 30 seconds 10 minutes there an increase content without any lowest part stem. Part through steam-girdled stem, but under these conditions no accumulation root. indicates that rapid occurred both living and dead tissues These results were correlated with localization tissue autoradiographs cross sections stem show three pathways translocation: (a) slow ...
