Abstract
Carnation (Dianthus caryophyllus L.) cultivar 'CSU White' was grown in raised greenhouse benches in soil and in gravel. Soil temperatures were controlled at 7.2 to 10.0, 15.6 to 18.3, and 22.8 to 25.6°C. Gravel temperatures were controlled at 7.2 to 10.0 and 15.6 to 18.3°C. Some plots in both soil and gravel were left to fluctuate with the air temperature. Warming was accomplished with electrical heating tapes buried 7.6 cm below the substrate surface. Cooling was maintained by cold water circulation through pipes buried at the same depth. The use of 6.1°C irrigation water had little effect on plot temperatures. The substrate temperature treatments had no significant effect on the production, quality, weight, length, or internode length of the flowers. Timing was not significantly affected during the duration of the experiment. Manipulation of soil temperatures over the range studied had no beneficial or detrimental effect on the growth and production of carnations.
