It’s remarkable that such diverse growth responses as phototropism, geotropism, and
response to physical contact are all controlled, at least in part, by a single chemical,
auxin or IAA. But what is even more remarkable is that many other common plant responses
are also controlled by this one chemical. Let’s look at some other plant growth
responses frequently observed in the garden, and look at the role auxin plays in each of
them. |
