Phenology and growth flower of Dianthus caryophyllus L. cv. ‘MOON LIGHT’ under greenhouse

Carnation crop in Colombia is one of the main income generating activities Colombian floriculture. However, growth dynamics and its relationship with thermal time are unknown. For this reason, objective research was to determine development carnation (Dianthus caryophyllus L.) cv. ‘Moon Light’ when grown a greenhouse Bogotá savanna. This developed based on phenological stages accumulation Growing Degree Days (GDD). Fresh dry weight fitted logistic model that generated sigmoid type curve. The flower 'Moon light' presented constant from 15.3 GDD (stage 0 rice) 777.6 (cut point). Absolute Growth Rate (AGR) increased slowly during phase I. It presents rapid gain until reaching cut-off point value 0.035 g per GDC an GDC. Relative (RGR) continuous decrease initial 0.0049 g-1 bullet stage 0.0024 at point. Through results obtained, floriculture sector will have technical tool within productive projection variety Light' greenhouse.
