Cytoplasmic pH dynamics in maize pulvinal cells induced by gravity vector changes.

abstract：:Apical segments of roots of Zea mays L. cv. Orla and cv. Anjou show a strong georeaction during 7 hours geostimulation. This is abolished by detipping the segments and restored by replacing the tips upon the apical cut surfaces. After exodiffusion of endogenous indoleacetic acid (IAA) the retipped segments showed a si...
