Small cut pieces of soft stems are placed in growth medium with follow...
Explanation:
When small cut pieces of soft stems are placed in a growth medium, the growth of the stems can be influenced by the presence of plant hormones. Plant hormones are signaling molecules that regulate various aspects of plant growth and development. Different combinations of plant hormones can have different effects on the growth of the stem cuttings.
Auxin and Cytokinin:
- Auxin is a plant hormone that promotes cell elongation and growth.
- Cytokinin is a plant hormone that promotes cell division and lateral bud growth.
- When auxin and cytokinin are present together, they have a synergistic effect on plant growth.
- The combination of auxin and cytokinin promotes both cell division and elongation, resulting in faster and more vigorous growth of the stem cuttings.
Gibberellins and Auxin:
- Gibberellins are plant hormones that promote stem elongation and seed germination.
- When gibberellins and auxin are present together, they also have a synergistic effect on plant growth.
- The combination of gibberellins and auxin promotes cell elongation and division, resulting in faster growth of the stem cuttings.
Gibberellins and Cytokinin:
- Gibberellins and cytokinin also have a synergistic effect on plant growth.
- The combination of gibberellins and cytokinin promotes both cell division and elongation, resulting in faster growth of the stem cuttings.
Abscisic Acid and Auxin:
- Abscisic acid is a plant hormone that inhibits plant growth and development.
- Auxin promotes cell elongation and growth, but when combined with abscisic acid, its effects are counteracted.
- The combination of abscisic acid and auxin will slow down the growth of the stem cuttings as the inhibitory effects of abscisic acid override the growth-promoting effects of auxin.
Therefore, the combination of Abscisic Acid and Auxin will show the slowest growth of the stem cuttings.

Abscisic acid is a growth inhibitor hence the combination will show slowest growth.
Abscisic acid causes bud dormancy, it also inhibits seed germination.
