Induced volatiles of experimental plants
We detected significantly more chemical compounds in induced than in
noninduced guavas (P = 0.009). Induced guavas had higher abundances of
β-Ocimene, Heptadiene, Cyclohexane. Other significant compounds were
α-Pinene, Copaene, Caryophyllene, and Tetraline. In elm samples,
β-Ocimene, α-Farensene and Tetraline were the most significant
compounds. Despite the induced elm produced more compounds that
noninduced elm, the difference was not statistically significant (Figure
S3). However, the induced elm had significantly higher abundances of
1-Butanol, 3-methyl-, acetate and
2-Butanone,4-(2,6,6-trimethyl-1-cyclehexen-1-yl).
