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.

Some of the most common heat-stress symptoms on ornamentals include lower-leaf yellowing, thin and elongated growth, delayed flowering, and small flowers.

Bedding plants that stop developing at moderately low temperatures can be labeled as cold-intermediate plants. This categorization is based on estimates of base temperatures derived from research data primarily generated at Michigan State University.

Bedding plants that stop developing at a relatively high temperature can be labeled as cold-sensitive plants. This categorization is based on estimates of base temperatures derived from research data primarily generated at Michigan State University.

Once flower buds are visible, adjusting the growing temperature has little or no impact on time to flower unless plants are held at low temperatures (50° F or less).

We quantified the effects of temperature and photosynthetic daily light integral on flowering time and characteristics of 15 Wave petunia cultivars, then generated temperature-based flowering time models for more predictable greenhouse scheduling.

The difference between the day and night temperature influences plant height of many floriculture crops, as well as greenhouse energy consumption for heating.

Retractable energy curtains save energy costs by serving as an insulative layer and reducing the amount of space heated. In addition, plants under the curtains can be at least a few degrees warmer than plants not under a curtain.

There are some bedding plant crops that tolerate high temperatures quite well, while others develop heat stress symptoms at lower temperatures.

Crop heating costs increase as production time increases, the size of the container increases, and the earlier in the spring that plants are finished.

The single largest advantage of using greenhouses to grow ornamental and food crops is the ability to provide desirable temperatures for plant growth and development.

Growers should avoid growing cold-tolerant and cold-sensitive crops together because crop timing, crop quality and heating costs cannot be optimized.
