Abstract
In consequence of insect feeding and saponin application tested quinoa plants released large amounts of volatile organic compounds (VOCs) to compare to control. For cv. ‘Faro’ these were the following components: (Z)-3-hexenal – (Z)-3-HAL, (E)-2-hexenal – (E)-2-HAL, (Z)-3-hexen-1-ol – (Z)-3-HOL, (E)-2-hexen-1-ol – (E)-2-HOL, (Z)-3-hexen-1-yl acetate – (Z)-3-HAC, 1-hexyl acetate – 1-HAC, (Z)-ocimene - (Z)-OCI, benzyl acetate - BAC, methyl salicylate - MAT, β-caryophyllene – β-CAR, (E)-β–farnesene – (E)-β-FAR. Cv. ‘Puno’ released 7 VOCs and these were: (Z)-3-HAL, (Z)-3-HOL, (Z)-3-HAC, (Z)-OCI, MAT, β-CAR, and (E)– β-FAR. The fragrance bouquet of the third of variety tested (cv. ‘Titicaca’) consisted of 6 components: (Z)-3-HAL, (E)-2-HAL, (E)-2-HOL, (Z)-3-HAC, (Z)-OCI, and β-CAR. In general, much larger VOCs emission was observed in plants after insect feeding compared to saponin applications and especially control.
