Temperature controls the rate of plant development and thus, crop timing. Temperature can also influence extension growth of plants, greenhouse energy consumption, and crop quality attributes. Additional information on temperature, including crop responses and greenhouse energy consumption, are listed in the articles below. Additional resources follow.
