This work aims to investigate the effects of two pathways using artificial vernalization for the production of cuttings of globe artichoke cultivar “Violet d’Hyères” on yield, earliness and marketable traits. The cultivation was set up and followed for two production seasons (2016/2018). The first pathway has targeted the production and the cool chilling (5 °C) of field’s ovoli for 2 and 3 weeks under darkness represented respectively by treatments F1 and F2 with the control treatment F0 (field’s ovoli without cold treatment). The second pathway was designed for the production of nursery’s ovoli as follows; T0 (nursery’s ovoli without cold treatment), T1 (nursery’s ovoli kept at a temperature of 5 °C for two weeks in the dark), T2 (nursery’s ovoli kept at a temperature of 5 °C for two weeks with a photoperiod of 14 h of light), T3 (nursery’s ovoli kept at a temperature of 5 °C for three weeks in the dark), T4 (nursery’s ovoli kept at a temperature of 5 °C for three weeks with a photoperiod of 14 h of light). Results have shown that the cold treatment under darkness especially for a period of three weeks has enhanced the vegetative development of plants derived from both field and nursery’s ovoli compared to their control treatments. For over two years, the highest rate in early yield was obtained in T3 for nursery’s ovoli and it was about 17 % from the total production whereas for field’s ovoli it was less than 14 % for treatment F2. For the total yield, vernalized nursery’s ovoli have recorded the best values ranging from 20.10 t ha−1 to 24.91 t ha−1, then followed by vernalized field’s ovoli with a maximum yield of 19.13 t ha−1. The lowest values in all parameters were often found in non- vernalized treatments T0 and F0. Traits of marketable heads such as head diameter and head weight were influenced significantly by treatments and varied according to the harvest period. These results lead us to conclude that dark-chilling has improved the development potential of cuttings which was after that reflected on yield, earliness and on commercial characteristics of the production.
