The summer is not optimal for grape growing and you're searching in your memory for something regarding plant hormones.
Explain 2 ways you could utilize plant hormones (choose from auxin, ethylene, cytokinin, gibberellin, abscisic acid, salicylic acid, jasonic acid) to compensate for a problem during growing. For each way:
• On a commercial scale, enhancing the level of _______ (hormone) can help to speed up fruit ripening. • What measure do fruit producers take to slow down fruit ripening that is caused by natural ethylene?• What is a ‘triple response’. Which plant hormone initiates a triple response? • A change in the ratio of ethylene to auxin controls abscission. In the autumn, the amount of __________ decreases, rendering the cells of the abscission layer more sensitive to __________.
On a hot, dry day a plant closes its stomata thereby conserving water. Which plant hormone is responsible for the closing of the stomata?
ethylene
abscisic acid
cytokinin
auxin
gibberellin

In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants.
