Mean (±SD) differences in maximum change in resistance for various carbon black-polymer composite sensors in response to volatiles from undamaged and damaged bolls after 6 s sample. = 13. Asterisks () indicate differences between treatment means significantly differ from zero (paired sample -test, 0.05 significance level).
