Indagine preliminare sulla frazione volatile di quattro cloni italiani di aglio provenienti da coltura in campo e da micropropagazione

Variation in aromatic fraction was investigated between 4 selected garlic clones from in vivo and in vitro cultures. The selected plant material included one Polesano white-type garlic clone and 3 Sulmona red-type garlic clones. The aromatic fraction was determined by means of headspace gas chromatography (HS-GC). Major compounds were diallyl disulphide and allyl methyl sulphide. The results of this preliminary work showed a large variation in several compounds respectively from in vivo and in vitro cultures: analyses of the aromatic fraction revealed differentiation between the different clones and showed three groupings, corresponding to the pooled Sulmona red-type garlic clones (Sulmona 3 and Sulmona 6) and the other individually separated clones.
