The transport of the synthetic auxin, picloram (4-amino-3,5,6-trichloropicolinic acid) was investigated in sections of petioles of Phaseolus vulgaris L. and Coleus blumei Benth. and stems of Pisum sativum L. Transport of (14)C-picloram was basipolar in all tissues, although the degree of polarity was dependant on age. The velocity of picloram movement was calculated at between 0.75 and 1.11 mm/hr. The amount moved in a given time, the flux, was dependant on the concentration applied and the length of the sections used. Picloram did not appear to be metabolized by the tissues during the transport experiments. When compared to the movement of other growth regulators, picloram transport bears marked similarities to that of 2,4-dichlorophenoxyacetic acid.
研究了合成生长素 4-氨基-3,5,6-三氯吡啶酸（picloram）在菜豆（Phaseolus vulgaris L.）和彩叶草（Coleus blumei Benth.）叶柄以及豌豆（Pisum sativum L.）茎切段中的运输情况。（14）C-picloram 在所有组织中均为双向运输，但其极性程度取决于组织的年龄。picloram 的运动速度在 0.75 到 1.11 毫米/小时之间。在给定时间内移动的量，即通量，取决于施加的浓度和使用的切段长度。在运输实验过程中，picloram 似乎没有被组织代谢。与其他生长调节剂的运动相比，picloram 的运输与 2,4-二氯苯氧基乙酸的运动具有明显的相似性。
