Title: What happens when plant shoot apex is removed from Nashville TN
Answered by: Barbara Medford and Jimmy Mills

QUESTION:

What happens to the plant when a shoot apex is removed?

ANSWER:

The shoot apex inhibits the lateral buds of the shoot through the production of indoleacetic acid (auxin), a phenomenon known as apical dominance. When the apex is removed or damaged, the lateral buds are released from inhibition due to reduced auxin levels, and they began to grow. This is the biology behind the practice of pinching out the tips of Chrysanthemums in order to get bushier plants, and pruning shrubs to encourage them to become hedges.

In case this is still a little murky, we searched on "pruning shoot apex" and found Basic Principles of Pruning Woody Plants
