One h and 3 h after point source application of [2-(14)C] ABA to the upper side of geotropically stimulated root tips of intact seedlings of Phaseolus coccineus L. a weak downward lateral transport of radioactivity was observed. A clear upward lateral translocation, however, occurred when ABA was applied to the lower side of the root tip. Thus a uniform distribution of radioactivity was established in horizontal roots regardless of the site of the application point, while in upright roots the distribution was asymmetric. Six h after ABA injection radioactivity was uniformly distributed in both the vertical and horizontal root tips.
在菜豆完整幼苗的向地性刺激根尖上侧施加[2-(14)C]脱落酸（ABA）后1小时和3小时，观察到放射性有微弱的向下侧向运输。然而，当ABA施加到根尖下侧时，会发生明显的向上侧向转运。因此，无论施加点的位置如何，水平根中的放射性都能建立均匀分布，而在垂直根中分布是不对称的。注射ABA后6小时，放射性在垂直和水平根尖中均均匀分布。
