Geocurvature of horizontally placed apical segments of maize (cv. INRA 258), the lateral curvature of half-decapitated segments in vertical position, and the curvatures of intact primary roots (horizontal or vertical) still attached to their caryopses were analysed in white light. The results may be explained in terms of the growth properties of certain endogenous regulators. The caryopsis could be the source of some precursors of growth inhibiting substances produced or released in the cap cells and also of growth activators. The relative effects of these factors - acting in the elongating zone of growing roots - clearly depend on the
