Question
Chapter 39, Problem 13TYU
Summary Introduction
To discuss: How the grazing of shoot tips by an herbivore affects the health, structure, physiology and biochemistry of a plant and which hormones would cause these effects / changes.
Introduction:
Plant-eating animals and insects are a kind of stress for plants. This mechanical stress due to wounding will produce the gas ethylene. This ethylene is a gaseous hormone responsible for the formation of triple response in plants.

A- Describes the mechanism of action at the pharmacological level of the Rubus Chingii plant.
B- What is the dosage to give Rubus Chingii herb to a dog and a cat?
C- What toxicities can the herb Rubus Chingii cause in animals?
Application of synthetic compounds could artificially modify the plant growth and development, i.e. inducing germination in dormant seeds, producing parthenocarpic fruits, promoting shoot initiation in tissue culture. Collectively, they are called ________________ which are synthetic compounds that imitate the organic naturally occurring substances that modify plant growth anddevelopment at low concentrations.
You have been chosen as the lead student gardener for the CSUMB Future Farmers of America Club (FFAC). Your club is looking to
you and your Bio211 plant experience to guide them. You arrive at the new FFAC garden plots and notice that while there are many
fruits on the apple tree, they seem to remain hard, sour, and green. Your club mates need the red, sweet apples in just a few days
for the apple competition.
Choose the best hormone to apply and the reason supporting its use:
Select one:
O a. Apply ethylene to the apples to increase ripening.
O b. Apply ethylene to slow ripening and increase chlorophyll levels.
O C. Apply auxin to increase parthenocarpy
O d. Apply gibberellins to increase fruit size.
O e. Apply auxins to decrease apical dominance and increase water intake.
