12

What are the 4 mechanisms if seed dormancy?

Mechanical - scarification

Light - photo chrome

Temperature - stratification

Chemicals - leaching

13

What was dr deno's hobby?

Figuring out why seeds germinate

14

What are the 5 main plant hormones?

Auxin
Cytokinins
Ethylene
Absidic acid
Gibberellins

15

What dies auxin do?

Tropic response and apical dominance.

16

What else can auxin do?

Cell expansion and fruit development

17

What plant part is most sensitive to auxin

The root

18

What do cytokinins do?

First found in herring Sperm and coconut milk

Cell division
Delays senescence
Suppressed root growth
Regulates cell cycle

What are the three functions if ethylene

Fruit ripening
Leaf abscission
Flowering

20

What types if plant dies ethylene have a positive effect and one negative?

It has a positive affect on aquatic plant growth and negative in others

21

What are the 4 functions of abscissic acid?

Stomata I closure
Seed dormancy
Inhibits growth

22

What is a gibberellin and what's it's purpose?

A hormone that allows seed germination and can promote stem elongation

23

In what three ways do plants control hormones?

Combinations
Concentration
Varied synthesis
