| Abstract/Contents: | "Autoradiographs of leaves of ryegrass plants (Lolium sp.) taking up radioactive zinc (65Zn) from soil showed an unusual pattern of label distribution. Tracer accumulated in a regular series of pulses along leaf veins. Pulses in adjacent veins occurred in juxtaposition forming the pattern of a band across the leaf. The possibilities of artifacts resulting from plant-culture technique or methods of preparing leaves for autoradiography were eliminated. The band effect in leaves of Lolium and other grass species occurred with 65Zn but not 59Fe or 54Mn. Leaves of Hordeum vulgare, Zea mays, Bromus rigidus, and two non-gramineous species did not show the band phenomenon with 65Zn. There was a close relationship between the frequency of bands and the rate of growth of a leaf. The band pattern was shown to be responsive to changes in daylength and temperature during growth. Possible origins of the band phenomenon are discussed." |
