“…For each artichoke hybrid cultivar, all morphological parameters studied were significantly increased by mycorrhizal symbiosis in agreement with previous research (Ruta et al, 2003;Morone Fortunato et al, 2005). Greater root density would form higher surface absorption areas of roots mainly due to external hyphal growth in the soil (Hardie and Leyton, 1981).…”

Most nurseries operating in Italy adopt high technologies and produce transplants that well suit and satisfy the grower’s need to produce high value crops. Mycorrhizas are discussed as a tool for improving and developing plant production in the nursery. Much research has been carried out on mycorrhizal symbiosis and we now know more about the symbiontic relationship between fungi and host plants. Plants receive numerous benefits from this symbiosis which are more macroscopic the earlier in the ontogenetic cycle this symbiosis is established. Therefore, it appears that the most effective period in which the inoculum should be made corresponds to the in-nursery growing stage. The earlier the plant is inoculated, the more evident the effect will be. In this study, several aspects related to the physiological foundations of arbuscular mycorrhiza in artichoke plants are presented. The main goal was to study the effects of mycorrhiza on the growth and physiological parameters of three hybrids of artichokes growing in the nursery. The experimental 3¥2 design included two treatments (with or without arbuscular mycorrhizal fungi) and three hybrids of artichokes marketed by Nunhems (Opal F1, Madrigal F1, Concerto F1). Mycorrhizal plants have greater shoot length, leaf area, shoot and root fresh and dry mass, and root density. This also corresponded with increased photosynthetic rates and stomatal conductance of mycorrhizal plants. Mycorrhizal colonization improves relative water content and increases proline concentration in vegetal tissue. Inoculation produced the most beneficial effect on hybrid Madrigal F1 and on hybrid Opal F1; the best mycorrhizal affinity was enhanced when compared to hybrid Concerto F1. The results showed that mycorrhizal symbiosis stimulated the growth of inoculated seedlings providing a qualitatively good propagation material

Micropropagation has been extensively used for rapid multiplication of many important plant species. However, its more widespread use is restricted by the often high percentage of plants lost or damaged when transferred to ex vitro condition. In this context, a biotechnological tool that allows to overcome these problems is the manipulation of mycorrhizas, because the establishment of the symbiosis with the root system of micropropagated plants gives positive effects on survival and growth rates after acclimatization. The purpose of this investigation was to evaluate the influence of mycorrhiza on plant survival and on growth responses of four different species of micropropagated plants: Cynara cardunculus L., Cucumis melo L. var. inodorus, Origanum vulgare L. subsp. hirtum and Spartium junceum L. Plants were micropropagated, multiplied and rooted in vitro in appropriate media under the following conditions: temperature 23°C photoperiod l6 h light intensity 60 µE s -1 m -2 . After rooting, the plants were transferred to the greenhouse in pots containing a sterile mixture of peat and perlite and inoculated with the fungus AM Glomus viscosum under controlled conditions. The number of plants surviving transplantation was recorded after 1 month. Fresh and dry weight of shoot and root systems were determined after 60 days growth for each plant. Leaf area index and shoot/root fresh weight ratio were also calculated. Mycorrhizal development was evaluated microscopically on subsample. Survival rate was variable between the four tested species. Mycorrhizal colonization improved the growth of all the micropropagated species. These results corroborate the key role of arbuscular mycorrhiza in inducing beneficial changes in the general developmental of micropropagated plants.

Research was carried out in order to evaluate the effect of mycorrhizal fungi in improving artichoke tolerance to salinity stress induced by sodium chloride. In fact, several studies have shown that arbuscular mycorrhizal (AM) fungus symbiosis enhances salt tolerance in some crops.The experiment was carried out with seedlings of artichoke cultivar '044' (Cynara cardunculus L. var. scolymus), treated or not with AM fungi (Glomus viscosum) at sowing.The root systems of both mycorrhizal and non mycorrhizal plantlets were carefully washed to remove the substratum and exposed to distillated water (control) and saline water (13 and 26 dS m -1 ) obtained by adding NaCl. The wilting trend was studied defining wilting indexes on the basis of visual characteristics. When the wilting had stabilized, the plant roots were washed in distilled water and then transferred to glass jars with distilled water until the recovery of the plantlets.The results indicate that AM fungi improve tolerance to salinity stress, confirming the beneficial effect of mycorrhizal fungi in abiotic stresses also for artichokes.
