Secondary plant metabolites as control agents of postharvest Penicillium rot on tulip bulbs

Fifteen essential oil components were screened for their antifungal activity towardsPenicillium hirsutum . From these, carvone, cuminaldehyde, perillaldehyde, cinnamaldehyde, salicylaldehyde and benzaldehyde were selected as the most potent inhibitors of in vitro growth. Growth inhibition by carvone was found to be reversible. Exposure to cuminaldehyde, perillaldehyde, cinnamaldehyde and salicylaldehyde caused irreversible inhibition of fungal growth. Storage of tulip bulbs in atmospheres containing cuminaldehyde, perillaldehyde, salicylaldehyde or carvone resulted in a significant reduction of the natural Penicillium infection. Dipping tulip bulbs in an aqueous solution of 3.9 mM cinnamaldehyde gave a 40-fold reduction of the fungal population but did not affect the bacterial population. Treatment of tulip bulbs with carvone, cuminaldehyde, perillaldehyde, cinnamaldehyde or salicylaldehyde had no effect on the total stalk length or the flowering capacity of tulip bulbs.
