Title: Control plant growth.
Course: Floriculture (18052-II) > Section: Applying Science to Plant Production

Control could include using

- natural plant growth regulators, including auxins, gibberellins, cytokinins, and ethylene
- chemical growth regulators, including B-Nine, Cycocel, A-Rest, Bonzi, and Florel (ethephon)
- non-chemical means (e.g., cultivar selection, light management, cultural procedures, container size, nutrient restriction, water stress)
- environmental factors that affect growth control (e.g., temperature, light, pH, moisture)
- spacing of plants
- pinching of plants
- disbudding of flowering plants.

Process/Skill Questions:

- What are the identified functions of plant growth hormones?
- How can plant growth be restricted through cultural measures?
- What is the importance of adequate spacing of plants in growing beds or benches?
