“…The activity of cell wall-degrading enzymes is an important factor affecting the postharvest abscission of fruit. The activity of various cell wall-degrading enzymes, including PG, POD, Cx, LOX and PE, changed signi cantly during grape fruit abscission (Chen et al, 2019), a pattern that has also been observed in other horticultural products, such as longkong, citrus and tomato fruit (Tsuchiya, et al, 2015;Deng, et al, 2016, Taesakul et al, 2018. The activity of cell wall-degrading enzymes is affected by various factors, such as application of 1.5 mM salicylic acid before harvest can inhibit their activity and prevent the softening of grapes .…”

‘Kyoho’ grape (Vitis viniera L. × Vitis labrusca L.) is the most widely cultivated table grape variety. However, it is prone to fruit abscission after harvest, which affects the development of the market. The aim of this study was to evaluate the effects of applying different concentrations of sodium lactate (0.1%, 0.5% and 1% NaL) on postharvest table grape preservation. After harvesting, ‘Kyoho’ grapes were immersed in sodium lactate solution at various concentrations (0 [as control], 0.1%, 0.5% and 1% NaL) for 2min and stored at 20±1℃ for 10 days. Physiological indicators including weight loss rate, browning level of rachis, contents of vitamin C, sugar, malondialdehyde (MDA), membrane permeability, and activities of polygalacturonase (PG), peroxidase (POD), cellulase (Cx) and lipoxygenase (LOX) were investigated. Additionally, it was also determined for ATP content, energy charge and activity of energy metabolism-related enzymes. These results showed that NaL treatment inhibited berry abscission and maintained berry quality due to the decrease of cell wall degrading enzyme activity, the increase of energy metabolism-related enzyme activities and high level of ATP content and energy charge. This study provides a new and effective method for the postharvest storage of table grapes that can help minimize economic losses.

“…During degreening treatment, ethylene application has been reported to increase the activity of both polygalacturonic acid enzyme (PG) and cellulase (Cx), which promote browning and calyx abscission [33]. The incidence of calyx senescence triggered by degreening depends mainly on the ethylene concentration and process duration [26,30,34], and it is also very cultivar dependent.…”

“…This auxin's mechanism of action is to reduce PG and Cx activities and to increase the lignin and water contents of fruit peel [37]. Despite this auxin having been widely employed and proving useful, it has been restricted by current European Union legislation, hence the need to find other synthetic auxins to avoid physiological changes in the calyx [33,35].…”

External color is a key factor that defines external citrus fruit quality. Degreening with exogenous ethylene exposure is a widely used postharvest treatment applied to promote external citrus fruit color development, mainly with those cultivars that reach internal maturity while their external peel color is still green. Ethylene plays a crucial role in the color change of citrus fruit because it induces two simultaneous, but independent, processes—chlorophyll degradation and carotenoid synthesis. However, it is important to know, in addition to the effect on skin color development, whether this treatment can negatively affect other fruit quality parameters. This chapter addresses the influence of postharvest degreening treatment on the physicochemical, nutritional, and sensory quality of citrus fruit.

“…Some natural food additives are reported to be used for preserving fruit and vegetables. For example, chitosan oligosaccharides can alleviate the calyx senescence of mandarin fruits by decreasing the abscisic acid content ( 19 , 20 ). Folic acid can inhibit the senescence of broccoli by improving the antioxidant capacity ( 21 ).…”

Broccoli (Brassica oleracea L. var. Italic) is rich in nutrition. However, it is susceptible to yellowing after harvest, leading to nutritional and economic losses. In this study, diacetyl, a natural food additive compound, was selected to inhibit the yellowing of broccoli florets and maintain the nutrient quality during storage time. It was found that 20 μl L–1 diacetyl treatment for 12 h could significantly delay the yellowing and decrease the weight loss and lignin content of broccoli florets. Meanwhile, diacetyl could maintain higher contents of chlorophyll, vitamin C and flavonoids and suppress the transcript levels of chlorophyll degradation–related genes in broccoli florets. Moreover, accumulations of reactive oxygen species (ROS) were inhibited by diacetyl treatment. Under diacetyl treatment, the generation of ethylene was prevented by inhibiting the activities and related-gene expressions of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase. Based on our findings, exogenous diacetyl could be employed as a novel bioactive molecule for retarding the yellowing and maintaining the quality of postharvest broccoli.
