Title: Manipulate temperature to affect plant growth.
Course: Greenhouse Plant Production and Management (18052-III) > Section: Demonstrating Plant Production

Manipulation should include

- establishing optimum and tolerable air temperature ranges
- calculating average daily temperature
- researching temperature recommendations
- regulating substrate temperature
- stratifying seeds
- chilling bulbs
- explaining how to control stem elongation through DIF and DIP.

Process/Skill Questions:

- When must a grower regulate the temperature of growing plants?
- Why would a grower manipulate soil temperature?
- How is temperature manipulated?
- How do DIF and DIP affect plant growth?
