Which of the following hormones can stimulate growth of branches (=intiates growth and development of axillary buds)?
| A. |
cytokinins when apical meristem is removed |
|
| B. |
ethylene |
|
| C. |
strigolactone that encourages buds to grow |

Homework Answers
Apical meristem cosists of auxins which regulate formation of axillary buds. once the apical meristem is removed we can use cytokinins to simulate growth of branches.
