Apical Dominance Flashcards
1
Q
What are the parts of the stem
A
apical bud
lateral bud
leaves
2
Q
What is the apical bud?
A
it is at the top of the stem which produces auxins - plant hormones
3
Q
What do auxins do?
A
they will promote growth at the apical bud
they inhibit growth at the laterbal buds
therefore, plant grows taller and doesnt compete with itself
4
Q
What is the apical bud dominant over?
A
lateral buds
5
Q
What happens to the auxins concentration with distance from apical bud?
A
it decreases
lateral buds are then less inhibited
6
Q
What happens if we remove the apical bud?
A
less auxins are produced
lateral buds are not inhibited - they start to develop
the plant becomes bushy
if auxin is added to top of cut stem, apical dominance continues
