Preharvest application of selenite enhances the quality of Chinese flowering cabbage during storage via regulating the ascorbate-glutathione cycle and phenylpropanoid metabolisms

6-Benzyladenine Treatment Maintains Storage Quality of Chinese Flowering Cabbage by Inhibiting Chlorophyll Degradation and Enhancing Antioxidant Capacity

“…The quality of harvested leafy vegetable deteriorates rapidly over time. They are prone to leaf yellowing, wilting, and nutrients degradation during storage and transportation [ 2 ]. This greatly reduces the nutritional value and commodity value, leading to a huge postharvest loss in leafy vegetable every year [ 6 ].…”

“…The fresh weight of Chinese flowering cabbages subjected to the different treatments was measured using a 0.01 g accuracy scale every two days during storage. Weight loss was calculated by subtracting the cabbage fresh weights at 2, 4, and 6 days from those at 0 days of storage, and the weight loss rate was expressed as a percentage of their initial weight at 0 days of storage [ 2 ].…”

“…Vitamin C content (Vc) was measured according to the method described in the previous report [ 2 ], with slight modifications. Briefly, cabbage leaves were ground to a powder using liquid nitrogen, and the sample powder (1.0 g) was then extracted with oxalic acid-EDTA solution (3.0 mL).…”

“…utilis Tsen et Lee) is one of the most important and widely-consumed vegetables in China [ 1 ]. It is popular because of its favorable taste and richness of nutrients, including vitamin C, carotenoids, dietary fiber, minerals, glucosinolates, phenolic acids, and flavonoids [ 2 ]. However, the storage and transportation of Chinese flowering cabbage are restricted because of rapid leaf yellowing, wilting, and nutrient loss after harvest [ 3 ].…”

“…Over the past few years, many studies have focused on technologies for delaying leaf senescence and maintaining vegetable quality after harvest. Our previous study found that preharvest treatment with selenium and SNP can effectively reduce leaf yellowing in Chinese flowering cabbage [ 2 ]. Oxidative damage induced by endogenous reactive oxygen species (ROS) was shown to be one of the main triggers of leaf senescence [ 3 ].…”
