Abstract

One of the most important problems of micropropagated early Mediterranean artichokes was found in the phenotypical and behavioural variations in the field which determined the loss of earliness at harvest and consequently a lack of interest in using this method of propagation. The present work aimed to establish an efficient protocol for the micropropagation and the mycorrhizal inoculation of Cynara cardunculus L. var. scolymus Fiori cultivar “Violet de Provence” and to evaluate in-field assessment of the plants. Microrosettes of “Violet de Provence” were established in vitro on a nutrient medium enriched with isopentil adenine (2ip), indoleacetic acid (IAA) and gibberellic acid (GA3). The shoots were subcultured in the some medium supplemented with 6-benzylaminopurine (BAP), while, for root induction, indoleacetic acid (IAA) was used. At the time of transplant in greenhouse, the plantlets were inoculated or not with Glomus viscosum strain A6 (AM fungus). 4-month-old micropropagated plantlets were transferred to the field at the end of summer and morphological and productive parameters were investigated. The results obtained in the first year showed an uniform growth in the field of the artichoke plants, both phenotypically and in their behaviour, and a maintenance of the earliness. The use of this technique in early types o
