Last Valentine's day, an 18-year old girl received a bouquet of flowers from the boy that she likes. She wanted to keep the cut flowers for a few more days so she asked for your advice on how she can retain the freshness of the flowers. Given this situation, what specific plant hormone would you recommend to her?
a. abscisic acid
b. auxin
c. ethylene
d. gibberellin
e. cytokinin
ties of the brain and spinal cord
B. Match the hormones that are supposed to be added to a plant in order to achieve the following
results:
a. Auxin
b. Gibberellin
c. Cytokinin
d. Abscisic Acid
e. Ethylene
19. unpollinated flowers are treated with this hormone so ovary enlarges and becomes a
seedless fruit
20. substitute for temperature or light cues in plant seeds to get them to germinate
21. black spots on banana skin are spots where these are produced inducing ripening
22. seeds/bulbs stay dormant during winter to ensure survival of the plant when it germinates
23. most grape growers spray this in vines to increase length of branches between fruit clusters
for more air spaces among fruits to lower fungal infections
24. sprayed on cut leaves and stems so they will remain green longer while unsprayed leaves
will tum yellow and die
