A continuous growth apparatus was used to measure the effect of cytokinin on auxin-induced elongation. The soybean hypocotyl segments elicited a bi-phasic response to auxin that appeared to be two overlapping responses. The first response, which began 12 min after auxin addition, was not inhibited by cytokinin, even after long preincubation in cytokinin, but the second response to auxin, which began about 30 min after auxin addition, was completely inhibited by cytokinin. Such overlapping reactions are shown, depending on the amount of overlap, to yield a variety of summation reactions, many of which resemble rate-time curves that have been previously reported. We have shown that the transient first phase of auxin-induced elongation is very similar to acid-activated growth, while the second phase is long lasting and very likely identical to the long-term response to auxin, as extensively studied in Avena, soybean, and other elongating cells.
