N1 - Nodes and internodes  on Goethes concept of the spiral tendencyStarting from the interesting phenomenon of biastrepsis Zwangsdrehung the helical twisting of shoots in which the rhythm of node and internode formation in the plant shoot deviates from a kind of continuum of both elements we discuss the question of the eonditions for this regular rhythm By presenting transitional series we try to show that there is no separation in principle between on the one hand the continuation of a main shoot ending in a flower through a side shoot and on the other hand the continuation of a leafy shoot through further stem internodes The end of the main shoot which separates the flower or a group of flowers from the continuing side shoot is thus compared with the leaf petiole the flower itself with the leaf blade Based on the phenomena for the particular terminal organ structures we assume that through an integrating richness of previously successively arising individual organ structures a dominance is presewed which also does not at first allow independent side shoots to emerge in its vicinity but instead includes them in itself Only after sufficient maturation of the terminal organ structure can previously nonintegrated older secondary meristems send out shoots Various observations suggest that even the stimulus for such new shoots arises from the terminal organ Corresponding to the basal break out of enclosed end buds in funnelshaped leaves or pitcherlike leaves ascidia we assume that unused central organ structures from the terminal organ break out sideways and can unite with and strenghten older secondary meristems Disturbances of the rhythmic interchange of terminal organ formation and continuation of growth are now explainable as a result of premature emancipation of normal shoot structures that are yet to be integrated in the terminal organ They can be caused just as much by excessive nourishment of the latter as by a deficiency of integrative power of weak terminal organs They lead to both incomplete terminal organ formation and incomplete continuation ot growth The respective ineomplete organs of on the one hand spreading and on the other hand shooting maintain an abnormal connection with one another and lead to growth restricted to spiral forms For Goethes relevant statements on the observed phenomena his deep insight can become clear in the underlying processes We try to show that apparently contradictory observations of later researchers when consistently thought through lead to interpretations that confirm Goethes ideas in a wholly new way whilst also helping to avoid the wrong interpretations of them that first suggest themselves
