| Abstract |
Die Pflanze transportiert Wasser in den Wasserleitungsröhren des Xylems vom Boden bis zu den Blättern (fasz. Leitung). Durch osmotische und imbibitorische Kräfte wird es durch die Zellmembranen zur Epidermis transportiert (extrafasz. Leitung). Durch fluoreszierende Stoffe werden die einzelnen Wassertransportphasen an Beispielen von Springkraut, Roggen und Helxine nachgewiesen.
The plant transports water in the conducting bundles of the xylem from the ground to the leaves (fascicular flow). It is transported through the cell membrane to the epidermis by the osmotic and imbibitory forces. (extrafasc. flow). The individual water transport phases are demonstrated in touch-me-not, rye and Helxine using fluorescent dyes.
