Abstract
The onset of rainfall during sweet cherry development can cause serious preharvest losses due to fruit cracking on tree.
Therefore, rainfall at specific phenological stages can affect fruit quality and total yield.
Some cultivars are particularly susceptible due to the incidence of persistent rains during the most advanced phenological stages.
This study focuses on the preharvest application of methyl jasmonate (MeJA) at different key points to reduce the incidence of sweet cherry cracking during ripening on tree and the influence of the phenological stage in which rainfall is coincident.
In addition, these fruits have a short shelf life during postharvest storage.
Therefore, in this study, we propose preharvest foliar applications with 0.5 mM MeJA on different sweet cherry cultivars (Prime Giant, Early Lory, Sweetheart and Staccato) to evaluate the influence of this natural elicitor on cracking tolerance during sweet cherry development on tree and at harvest time during several growing seasons.
After studying the results, we found that preharvest treatments were successful to reduce fruit cracking and improve postharvest quality.
In addition, it delayed fruit ripening on tree in general for the cultivars studied.
This delay in ripening could be an interesting factor in terms of plot management, and therefore helpful in the adaptation to climate change providing on the other hand, sweet cherries with higher quality during postharvest storage.
