AI Summary & Key Takeaways
AI InsightThe results showed that with decreasing planting density, the number of flowered shoots and flowered shoot fresh weight per plant (shoots/plant and g/plant) increased in all cropping seasons, and the times from pruning to harvest shortened in lower planting densities in the 3rd cropping season (September'93-March'94).

Abstract
This study was carried out to determine the effect of planting density on yield, quality and productive energy consumption for photoperiodic lighting in Gypsophila paniculataL.'Perfecta' growing under unheated plastic greenhouse conditions for 4 cropping seasons, at the Horticultural Research Institute (Erdemli, İçel-Turkey), during 1992-1994. In the study, planting densities at 6.80 plants/m 2 , 3.03 plants/m 2 and 1.70 plants/m 2 with 40, 60 and 80 cm triangle planting systems, and planting density at 1.67 plants/m 2 with 100x60 cm planting system were used. The results showed that with decreasing planting density, the number of flowered shoots and flowered shoot fresh weight per plant (shoots/plant and g/plant) increased in all cropping seasons, and the times from pruning to harvest shortened in lower planting densities in the 3rd cropping season (September'93-March'94). In contrast, with increasing planting density the length of flowered shoots, number and fresh weight of flowered shoots per square meter (shoots/m2 and kg/m2) increased, and energy consumption for photoperiodic lighting per flowered shoot and per kilogram of flowered shoot fresh weight (Wh/shoot and Wh/kg) decreased considerably.
