title: Physiological evidence for the accumulation of restrained wall loosening potential on the growth-inhibited side of graviresponding rye coleoptiles.
abstract: Subsequent to inversion, horizontally pre-gravistimulated coleoptiles exhibit an increased gravicurvature capacity as compared to vertically pre-gravistimulated and subsequently horizontally gravistimulated coleoptiles. This indicates that gravistimulated inhibition of growth of the upper organ flank during gravicurvature is mediated via the retention of wall loosening potential. After inversion, this potential contributes to enhanced cell extension on the then physiologically lower side.
