摘要: Abstract An ABA pretreatment enhanced the geotropism of maize (cv. LG 11) root segments. Such stimulation was much stronger for georeacting roots in darkness. When applied asymmetrically on lower part applical cut end decapped segments, it induced a downward curvature which increased with increasing concentration. Using GC/MS technique, found tip: light exposed containing more than those kept But no changes total level were obtained between vertical and horizontal This indicates that increase growth inhibitor amount growing zone - could explain positive has to be related concomitant decrease their upper this zone, concentration being constant.
