Cannabis/hemp seed germination percentage and rate across constant temperatures, including cultivar-specific cardinal temperature estimates and priming effects. Use study-specific values as examples, not universal species thresholds.
Visual lesson 07
Thermal limits & germination rate
Separate final germination percentage from the speed of germination, then use hemp seed studies to show how temperature can alter both while keeping published cardinal-temperature estimates specific to the tested cultivar, seed lot, and method.
Primary visual specification
Temperature-response curve with germination percentage and rate separated
Create an academically accurate temperature-response curve with germination percentage and rate separated for the Thermal limits & germination rate lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.

Why should a Cannabis seed temperature study separate final germination percentage from germination rate?
