Article Figures & Data
Figures
- FIGURE 1.
Cut-shoot method allows rapid accumulation of radionuclide in plant structures. Scintigraphy of cut shoot reveals accumulation in stem and leaves. Note absence of accumulation in fruit itself. 99mTc-pertechnetate accumulates in unripe fruit but not in ripe fruit.
- FIGURE 2.
Wick method demonstrates bidirectional movement of tracer from wick site (arrow). Distal part of grape stem is at top right of image, and proximal (backflow) part of stem is at bottom left of image.
- FIGURE 3.
Activity applied to leaf (left) migrates down stem. Activity is concentrated at junction of main and branch stems (right).
- FIGURE 4.
Merging of photographic and scintigraphic image data for improved localization. Under ideal circumstances, display would be in color.
