Use of secondary plant metabolites for the control of postharvest fungal diseases on flower bulbs.

ABSTRACT

Fifteen essential oil components were screened for antifungal activity towards Penicillium hirsutum and P. allii. Carvone, cuminaldehyde, perillaldehyde, cinnamaldehyde, salicylaldehyde and benzaldehyde were selected as the most potent inhibitors of in vitro growth. Growth inhibition by carvone was reversible. Exposure to cinnamaldehyde resulted in irreversible inhibition of the growth of both fungi. With the 4 other aldehydes, intermediate effects on growth were observed. Storage of tulip bulbs in an atmosphere containing cuminaldehyde, perillaldehyde, salicylaldehyde or carvone resulted in a significant reduction of the outgrowth of the natural Penicillium infection. Under these conditions, no significant antifungal effect of cinnamaldehyde was observed. Treatment of tulip bulbs with each of the 6 antifungal compounds had no effect on the total stalk length and the flowering capacity.
