“…In order to improve in vitro artichoke rooting, various investigations were done on the use of different types and concentrations of growth regulators [26,[29][30][31][32][33][34][35][36], the addition of supplements such as activated charcoal [36][37][38], cyclodextrin [39], or pretreatments (darkness, two-phase) [30] have been carried out. In the present research, such as already tested in several different artichoke genotypes [9,19,40,41], the addition of IAA at high concentration (10 mg L −1 ), in combination with the increase in sucrose concentration from 20 to 30 g L −1 allowed us to achieve a satisfactory percentage of rooting and a root system characterized by a strong root length of 4.5 cm at the moment of plantlet transplanting into greenhouse. The same concentration of IAA was also applied to induce rooting by Ozsan and Onus [38,42] on open-pollinated cultivars and F1 hybrids and Tavazza et al [43] on cv.…”

“…During the multiplication cycles, corresponding to the most extended phase of in vitro culture, three different growth media (MS519, MS519-A, and LS452) were tested as an alternative to the BM, already successfully used on several autumn Apulian landraces [9,19,27]. Among them, the most effective for the shoot proliferation index was MS519-A, despite the fact that the results obtained with BM were not statistically different.…”

“…To increase the number of produced plants maintaining a sanitary status, the nursery sector depends more and more on a tissue culture propagation system. In vitro cloning of artichoke tissue culture is the key to a rapid, large, and homogenous propagation of material on a mass scale, in limited space, producing healthy and genetically uniform plants [8,9]. Once the material is micropropagated to the desired level and established ex vitro, the nursery might produce plants fast and in a sustainable way using mycorrhizal infection of the roots.…”

“…Another role of the mycorrhiza could be a competition with fungal diseases due to the fungi mutualistic association; in artichoke, e.g., with Verticilium dahalie, [14]. The advantages of the symbiosis are also in improving the productivity and quality of field crops [15], that is particularly visible in artichoke [9,16].…”

Artichoke (Cynara cardunculus L. var. scolymus (L.) Fiori) is a perennial plant of the Asteraceae’s family native to the Mediterranean basin. Italy has rich artichoke biodiversity, but many landraces are subjected to genetic erosion caused by increasing use of commercial varieties that are more homogenous in production. An Apulian landrace ‘Troianella’ was established in vitro to valorize and provide high-quality material for propagation in nurseries and, subsequently, for cultivation in production fields. The shoot proliferation was tested on four different growth media, adding cytokinin (-6-benzylamminopurine (BAP-0.05 mg L−1). Among these, the best results were achieved on MS519-A and BM media in which MS macronutrients were supplemented with additional doses of CaCl2 and MgSO4 (plus 120 mg L−1 and 190 mg L−1, respectively). In vitro root induction was obtained with 10 mg L-1 of Indole-3-acetic acid (IAA) and 30 g L−1 of sucrose. Plants derived from tissue culture were acclimatized in greenhouse using mycorrhizal symbiosis to increase survival during the acclimatization phase and to improve their performance after transplanting in field. Three arbuscular mycorrhizal (AM) fungi (Septoglomus viscosum, Funelliformis mosseae, and Symbivit, a commercial mix) were added to a sterile substrate and compared to a sterile control without any AM fungal inocula. After 3 months, the best growth and plant appearance were on substrates with S. viscosum fungus or the commercial mycorrhizal fungi mix. The results supported a development of an efficient micropropagation protocol and a production of high quality plant material for sustainable farming of the endangered ’Troianella’ landrace.

Mycorrhizal Inoculation Improves Plant Growth and Yield of Micropropagated Early Globe Artichoke under Field Conditions

The micropropagation appears to be a valid alternative method for the production of large-scale, phenotypically homogeneous, and disease-free plants, particularly for spring globe artichoke genotypes. Nevertheless, micropropagated plants have some problems during the acclimatization in field environments. The inoculation with arbuscular mycorrhizal fungi appeared to overcome the transplanting stress. Therefore, a comparison was drawn between the field performances of different vegetative propagation techniques (micropropagated/mycorrhized and offshoots cultivation) of early globe artichoke clones over two growing seasons. The micropropagation/mycorrhization appeared to deliver a better field performance in terms of both plant growth and productivity traits as compared with offshoots cultivated. In particular, the micropopagated/mycorrhized plants exhibited the highest vegetative growth values than the offshoots of the cultivated ones, such as the plant height and the main floral stem length. The micropopagated/mycorrhized plants were also more productive, exceeding the head yield of offshoots cultivated ones by about 63%. However, the micropopagated/mycorrhized plants accumulated almost a month late on the first harvest respect to offshoots cultivated ones. Our data also showed that the effects of the new proposed propagation method were genotype- and season-dependent. Accordingly, some plant growth and productivity traits showed significant ‘propagation method × genotype’ and ‘propagation method × growing season’ interaction. This study revealed that the micropropagation, as well as the mycorrhization, could represent an efficient and sustainable cropping system to reintroduce and increase the productivity of autochthons landraces.
