Features of Plant Hormones

The following are the important features of the role of plant hormones in growth and development:

The hormone may initiate one response in one part of the plant and an entirely different response in another part.
Quite often interaction of various hormones may elicit an expected or different response from what each hormone will individually produce. They may work synergistically or antagonistically.
The effect of a hormone may even vary with concentration, during different times of the year or the developmental stages of the plant.

These variables make it difficult to answer specific questions on the role of plant hormones in growth and development. Thus this area is one of the most challenging areas of physiology.
