Definition of chilling requirementsCategorized under "General"
Definition as written by talinum:
The requirement of plants for a specific period of dormancy below a particular temperature in order for them to initiate flowering.
Definition as written by Resin:
For most temperate plants, chilling requirements are fulfilled by temperatures of between 0° and 5°C, when plants are not completely dormant. Plants are fully dormant when below 0°, and temperatures below freezing do not help fulfil chilling requirements.
