“…However, increasing MJ concentration from 1 to 25 µg/L did not increase the anthocyanin content of lychees. It was reported that exogenous application of MJ at a suitable concentration enhanced the accumulation of anthocyanins in strawberries and apples (Tamari et al. 1995; Rudell et al.…”

The application of methyl jasmonate (MJ) for the control of pericarp browning of harvested lychees in relation to the levels of anthocyanins and (–)‐epicatechin was investigated. Lychees were dipped for 3 min in 0.6 µg/L MJ + 0.05% Sportak, 1 µg/L MJ + 0.05% Sportak, 5 µg/L MJ + 0.05% Sportak, 25 µg/L MJ + 0.05% Sportak or 0.05% Sportak (control). In this study, contents of anthocyanins (–)‐epicatechin and lipofuscin‐like substance, and browning index of harvested lychees during storage were determined. The activities of phenylalanine ammonia lyase (PAL), polyphenol oxidase and peroxidase were also measured. The treatment with MJ significantly maintained the contents of anthocyanins and (–)‐epicatechin, delayed the accumulation of lipofuscin‐like substance and extended the shelf life of lychees. Furthermore, MJ treatment increased PAL activity, which can account for the maintenance of anthocyanin or (–)‐epicatechin content. After these treatments, 1 µg/L MJ was effective in inhibiting pericarp browning and in maintaining the contents of anthocyanins and (–)‐epicatechin of lychees. Thus, it is suggested that maintenance of anthocyanin or (–)‐epicatechin contents could be an important factor for controlling pericarp browning of lychees during storage. PRACTICAL APPLICATIONS Lychees are highly perishable after harvest because of rapid skin browning as a result of anthocyanin degradation and (–)‐epicatechin oxidation by polyphenol oxidase or peroxidase in the presence of peroxides, and the subsequent accumulation of lipofuscin‐like substance, a final product of the autooxidation of lipid hydroperoxides, malondialdehydes and proteins of cells. This study exhibited that treatment with 1 µg/L methyl jasmonate (MJ) inhibited significantly the degradation of anthocyanins and the oxidation of (–)‐epicatechin, and delayed significantly the accumulation of lipofuscin‐like substance and pericarp browning of lychees. Therefore, application of MJ could be an important strategy to extend storage life and maintain the quality of harvested lychees based on the maintenance of anthocyanin or (–)‐epicatechin content.

“…Anthocyanins, for example, are associated with enhanced resistance to the effects of chilling and freezing [82, 83, 84, 85, 86], to heavy metal contamination [87, 88, 89, 90], to desiccation [91, 92, 93], and to wounding [76, 94, 95]. It is not clear at this stage whether the apparent ameliorative properties stem from one or more types of mechanism.…”

Anthocyanins, the pigments responsible for spectacular displays of vermilion in the leaves of deciduous trees, have long been considered an extravagant waste of a plant's resources. Contemporary research, in contrast, has begun to show that the pigments can significantly influence the way a leaf responds to environmental stress. Anthocyanins have been implicated in tolerance to stressors as diverse as drought, UV-B, and heavy metals, as well as resistance to herbivores and pathogens. By absorbing high-energy quanta, anthocyanic cell vacuoles both protect chloroplasts from the photoinhibitory and photooxidative effects of strong light, and prevent the catabolism of photolabile defence compounds. Anthocyanins also mitigate photooxidative injury in leaves by efficiently scavenging free radicals and reactive oxygen species. Far from being a useless by-product of the flavonoid pathway, these red pigments may in some instances be critical for plant survival.

“…Wang and Zheng reported that treatments with MJ increased the accumulation of anthocyanins, flavonoids, total phenolics, and antioxidant capacities in raspberry fruit. The induction of biosynthesis of anthocyanins with application of JA and MJ has been found to be associated with signal transduction . MJ treatment has been reported to induce the expression of some anthocyanin biosynthesis related genes such as chalcone synthase, anthocyanidin synthase and leucoanthocyanidin dioxygenase in Arabidopsis .…”
