Thiamine-(14)C moved through petiolar sections of Lycopersicon esculentum Mill. var. Michigan State Forcing with striking similarity in kinetics to auxins and gibberellic acid moving through similar sections of other green plants. Thiamine moved with strong basipetal polarity, at a velocity of 3 to 5 mm per hour, and emerged unchanged into the basal receiver agar block, judging by chromatography. This lends support to the hypothesis that polar movement is a property of several classes of plant hormones, rather than being restricted to the auxins (as previously believed).
硫胺素-(14)C 通过 Lycopersicon esculentum Mill. var. Michigan State Forcing 的叶柄段的移动方式与生长素和赤霉素在其他绿色植物的类似叶柄段中的移动方式非常相似。硫胺素以强烈的向基极性移动，速度为每小时 3 至 5 毫米，并通过色谱法判断，进入基部接收器琼脂块时保持不变。这为极性运动是几类植物激素的特性，而不是仅限于生长素（如先前认为的那样）的假说提供了支持。
