Question

What conclusion can you draw after observing the results in dishes 1 and 2? Do tomatoes contain a hormone that inhibits germination? Give evidence to support your answer

Answer 1

Abscisic acid (ABA) inhibits germination.

Step-by-step explanation:

Tomatoes contain a hormone that inhibits germination which is present in the epicarp of the tomato fruit. The hormone which prevent the tomato to germinate is called abscisic acid (ABA). If the tomato fruit produces this hormone no germination will occur but when the production of this hormone stops the germination will occur. For example, if we place a tomato in an environment, no germination will occurs due to the presence of abscisic acid.
