dc.description.abstractMiChestnut3 is a project of the company DEIFIL whose main objective is to produce more resistant and productive hybrid chestnut (Castanea sativa Mill.) seedlings through micropropagation and mycorrhization techniques. In this work, in addition to the agronomic traits of the micropropagated mycorrhizal chestnut seedlings, it was also important to evaluate the changes induced by mycorrhization in the phenolic profile of these plants. Phenolic compounds are plant secondary metabolites involved in plant-microbe interactions/symbiosis and act as signaling molecules in the establishment of arbuscular mycorrhizal symbioses, as well as in plant defense mechanisms [1]. According to the literature, considerable increases in phenolic compounds in host plants as a result of arbuscular mycorrhizal fungus inoculation have been reported during the progression of the infection [1]. Therefore, this work was carried out to study the impact of the type of fungal inoculum and the period of mycorrhization (before or after potting) on the qualitative and quantitative profile of phenolic compounds of the roots and leaves of the chestnut seedlings produced by DEIFIL. After collection and lyophilization of the plant material, hydroethanolic extracts were prepared and the phenolic compounds were characterized by HPLC-DAD-ESI/MS [2]. Ellagic acid derivatives and Oglycosylated flavonoids were the major phenolic compounds in both plant roots and leaves, which agreed with previous reports [2,3]. A statistical analysis showed that the type of inoculum and period of mycorrhization significantly (p<0.05) affected the phenolic profile of the chestnut hybrids. In general, the mycorrhizal seedlings with the fungi Amanita caesarea and Boletus edulis were those that presented the highest levels of phenolic compounds. Relationships between the levels of these signaling compounds and the agronomic performance of chestnut seedlings were also found. The results bring new perspectives into the future production of a hybrid chestnut tree resistant to ink disease in the main traditional Portuguese varietiespt_PT
