Physicochemical Characterization of Crithmum maritimum L. and Daucus carota subsp. gummifer (Syme) Hook.fil. and Their Antimicrobial Activity against Apple Tree and Grapevine Phytopathogens

Crithmum maritimum and Daucus carota subsp. gummifer are two species of the Apiaceae family that share multiple characteristics: both halophitic, live on cliffs in same geographic habitats, edible. While C. is rich essential oils flavonoids, D. terpenes a gum producer. In work presented herein, biomass these wild plants bioactive compounds present their extracts have been studied by elemental thermal analysis, infrared spectroscopy, gas chromatography-mass spectroscopy. To explore bioactivities, hydroalcoholic major constituents (apiole geranyl acetate carota), either alone or combination with chitosan oligomers, were assayed vitro against bacterial fungal pathogens affect apple trees (Malus domestica) grapevine (Vitis vinifera). Remarkable inhibition was observed Erwinia amylovora, causal agent fire blight apple; Xylophilus ampelinus [syn. vitivora], grapevine; Diplodia seriata, virulent pathogen grapevines also causes canker, leaf spot fruit rot apple. view effectiveness three phytopathogens, potential application medicinal organic farming may be envisaged.
