Conjugated polyamines and hydroxycinnamic acids in grape berries during Botrytis cinerea disease development: differences between ‘noble rot’ and ‘grey mould’

摘要: ata are provided on contrasting levels of different categories polyamines and hydroxycinnamic acids during the course disease development due to Botrytis cinerea ripe grape berries that led either noble rot or grey mould. Noble was mainly characterised by a greater accumulation wall-bound at beginning infection, whereas process mould marked an increase conjugated polyamines. During coumaric acid predominant present in both healthy infected regardless infection stage, ferulic lower concentrations than other identified. Moreover, changes relative proportions each three considered showed patterns according sort which developed. The roles these compounds (hydroxycinnamic polyamines) their involvement interaction between grapevines is discussed. mould, end caffeic predominated mid stage.
