Abstract
Reducing energy use in greenhouses contributes to the profitability of the horticultural industry. Important energy savings can be realized through the use of temperature integration. However, such a greenhouse heating strategy is only acceptable for commercial purposes if there are no adverse effects on plant growth and quality. During a three month study, Hedera helir L. 'Green Ripple' and Hedera helix L. 'Shamrock' were subjected to a day/night temperature regime of 20/20 degrees C (control) and two treatments with temperature integration over 24 h and 4 d, respectively, and a DIF of 13.5 degrees C while maintaining the average temperature at the same level of the control. Temperature integration had a positive effect on plant growth. Shoot length and maximum shoot growth rate rose up to 37.3% and 57.01%, respectively, when temperature integration was applied. Furthermore, after three months shoot fresh weight was highest for the temperature integration treatment with an integration period of 4 d. As shoot length can be defined as one of the major quality characteristics of H. helix, it can be concluded that temperature integration with a DIF of 13.5 degrees C and a relatively long integration period (e.g. 4 d) supports commercial production of H. helix.
