Abstract

Young internodes of Coleus blumei Benth. have long been known for their sizable amount of acropetal indoleacetic acid movement. However, plants of the same clone, under improved growing conditions, now show almost absolute basipetal polarity of (14)C-indoleacetic acid, as measured by liquid scintillation counting of (14)C in the receiver cylinders of agar. The ratio of basipetal to acropetal movement is now as much as 85:1, instead of the 3:1 ratio found years ago under conditions providing slower growth.

摘要

茎长的爵床植物幼嫩节间一直以来都以其可观的向顶性吲哚乙酸移动而闻名。然而，相同无性系的植株，在改良的生长条件下，现在通过对琼脂接收管中（14）C 吲哚乙酸的液体闪烁计数，表现出几乎绝对的向基极性。向基与向顶移动的比例现在高达 85:1，而不是多年前在提供较慢生长条件下发现的 3:1 比例。
