“…Xia et al (2009) manipulated the BR levels in cucumber (Cucumis sativus) through a chemical genetics approach and found that BR levels were positively correlated with the tolerance to cold stresses. In recent years, a few studies have reported that BR treatment increased resistance to low temperature and disease, delayed senescence and maintained postharvest quality in horticultural crops, such as mango (Li et al 2012), green bell pepper , jujube (Zhu et al 2010) and tomatoes (Aghdam and Mohammadkhani 2014). These results suggest that BR has potential application as a postharvest treatment for maintaining a high-quality product.…”

The combined effects of carboxymethyl chitosan (CMCH) coating and brassinolide (BR) on the sensory quality and physicochemical characteristics of green asparagus (Asparagus officinalis L.) stored at 4 ± 1C and 90-95% relative humidity for 24 days were investigated. The combined treatment (CMCH + BR) inhibited respiration rate and water loss, maintained higher concentrations of ascorbic acid, total phenolics and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity, and restrained the increase of malondialdehyde and electrolyte leakage of asparagus spears during storage. The activities of superoxide dismutase, ascorbate peroxidase and catalase were enhanced by CMCH + BR, while the activity of phenylalanine ammonia lyase was significantly inhibited, which resulted in lower lignin content and tender texture. Sensory evaluation also confirmed that the efficacy of CMCH + BR treatment was better than that of CMCH coating or BR treatment alone. Our study suggests that CMCH + BR coating has the potential to maintain the quality of asparagus spears and extend its postharvest life. PRACTICAL APPLICATIONSThis paper investigates the effect of carboxymethyl chitosan combined with brassinolide on the storage quality of green asparagus. The results presented demonstrate that the effect of the combined treatment on the sensory quality and physicochemical characteristics should be considered by processors as a preservation technique.

“…One unit of PLD was defined as the amount of enzyme that catalyzed the formation of 1 nmol d ‐nitrophenol h −1 . One unit of LOX was defined as the amount of enzyme that caused an increase in absorption of 0.01 min −1 at 234 nm and 25 °C when linoleic acid was used as the substrate . Protein content in the enzyme extracts was determined with the Bradford method using bovine serum albumin as a standard.…”

Postharvest melatonin treatment reduces chilling injury in sapota fruit

et al. 2020

BACKGROUND Sapota is a popular tropical fruit characterized by a very short postharvest life. Low‐temperature storage prolongs postharvest life of sapota fruit, but chilling injury symptoms can develop if the storage temperature is less than 14 °C. There have been no reports on the effects of postharvest melatonin application on the development of chilling injury in sapota fruit during cold storage. The objective of this study was to investigate the effects of different concentrations of postharvest melatonin application (0, 30, 60 and 90 μmol L−1) during cold storage (8 °C) for up to 30 days with an additional 1‐day shelf life at ambient temperature. RESULTS All melatonin treatments reduced chilling injury symptoms, reduced electrolyte leakage, malondialdehyde (MDA) content, H2O2 and superoxide anion (O2−), and increased proline content and the activity of superoxide dismutase (SOD), catalase (CAT) and γ‐aminobutyric acid (GABA), and reduced the activities of phospholipase D (PLD) and lipoxygenase (LOX) compared to the control. CONCLUSION Postharvest melatonin treatment could be a useful strategy for reducing chilling injury during cold storage and transport of sapota fruit. The results indicate that melatonin reduces chilling injury of sapota fruit through maintaining membrane integrity, SOD and CAT activities, and reducing PLD and LOX activities. © 2019 Society of Chemical Industry

“…BRs and related composites evoke antioxidant defense system and ultimately improve plant growth and metabolism in different plants exposed to both high [41] and low temperature [42]. Plant exposed to chilling stress BR reduce the ion outflow [43], whereas, 24-epiBL felicitate enzymatic activity (antioxidant) in grapevines exposed to chilled treatment [44].…”

“…Furthermore, in cucumber exogenous application of 24-epiBL mitigate chilling-induced reticence of photosynthesis by dropping ROS generation and enhanced activities of SOD, APX. The reduction in chilling injury, ion leakage, membrane integrity, and enhanced osmoprotectant, phenylalanine ammonia-lyase activity due to ameliorative effect of ample concentration of BR (3.0 and 6.0 µM) exogenously applied to tomato plants [42]. Furthermore, the physiological and molecular impact of 24-epiBL on tomato plants are more tolerant to high temperature as compared to an untreated plant.…”

Brassinosteroids (BRs) are the most important growth hormones which are steroidal in nature play crucially involved in growth and progressions of the plant. In recent years, advancements done in accessibility of biological possessions and approaches led to the most applicable mechanisms involved in BRs de novo synthesis, translocation and signaling pathways. The current researchers are also associated with the flexible roles of BRs. From the previous studies, it was manifest that BRs interaction with salicylic acid, abscisic acid, auxin, gibberellin, ethylene, cytokinin, and jasmonic acid in controlling numerous morphophysiological processes in plants. In this section, an effort is made to understand mysterious development and growth-linked either directly or not directly to BRs signaling and its intra-and interrelations with various phytohormones. This, in sequence, will support emerging extrapolative representations to moderate various valuable qualities in plants and address current encounters in agriculture.
