Efficacy of postharvest treatments with acibenzolar-S-methyl and methyl jasmonate againstBotrytis cinereainfecting cutFreesia hybridaL. flowers

Induced Resistance for Plant Disease Control

“…MeJA and ASM have been evaluated as preharvest and as postharvest treatments to protect freesias against petal specking (Darras et al, 2005(Darras et al, , 2006(Darras et al, , 2007. MeJA and ASM have been evaluated as preharvest and as postharvest treatments to protect freesias against petal specking (Darras et al, 2005(Darras et al, , 2006(Darras et al, , 2007.…”

Novel Elicitors Induce Defense Responses in Cut Flowers

“…Camarosa fruit with ASM failed to reduce natural infection by B. cinerea at 5°C (Terry & Joyce, 2004b). Generally, ASM tended to provide protection on freesia flowers at lower incubation temperatures (Darras et al, 2007). However, it was not clear whether such disease reductions were the result of the induction of host's defence responses or a direct fungitoxic activity measured in the same study.…”

“…Irrespective to the concentration tested, ASM provided no protection to artificially inoculated freesia flowers (Darras et al, 2007). However, natural infection was significantly (P < 0.05) reduced after ASM treatment during storage at 5 and at 12°C.…”

“…Lesion diameters on the detached freesia petals were significantly reduced with increasing MeJA spray, pulse or gaseous concentrations (Darras et al, 2007). The first published evidence of postharvest MeJA spray treatments enhancing protection of cut flowers against B. cinerea was the work by Meir et al (2005) on cut roses.…”

“…Additionally, a considerable work on postharvest application of ASM on ornamentals has been published the recent years (i.e. Darras et al, 2007). ASM was introduced as a potent inducer of SAR and treated plants were resistant to the same spectrum of diseases as plants activated naturally Friedrich et al, 1996).…”
