CHEMICAL DEFENSE RESPONSES IN Eucalyptus globulus (Labill) PLANTS

This study evaluated the expression of defense compounds by the secondary metabolism of Eucalyptus globulus plants subjected to attacks by the insect Ctenarytaina eucalypti (blue gum psyllid) and abiotic mechanical damage using gas chromatography with flame ionization detection (GC-FID) and mass det...
