“…The higher radical-scavenging activity of CH + EBR-treated fruit may be attributed to the enhanced antioxidant enzyme activity induced by EBR, thereby improving the fruit’s overall antioxidant capacity and scavenging ability [ 61 ]. In support of our findings, previous studies have demonstrated enhanced CAT, superoxide dismutase (SOD) and ascorbate peroxidase (APX) antioxidant enzymes activities in mandarins [ 62 ], mushrooms [ 63 ] and grapefruits [ 42 ] treated with EBR. The authors further reported that enhanced antioxidant enzyme activities were correlated with reduced H 2 O 2 production, confirming the improved radical-scavenging ability of treated fruit.…”

“…The suppression of EL by EBR treatments was also reported by Aghdam and Mohammadkhani [37] on tomato, Pakkish et al [42] on grapes and Wang et al [35] on kiwifruit. The literature suggests that the EBR hormone alleviates membrane damage by regulating the activity of antioxidant defence systems, which inhibit the burst in accumulation of toxic ROS.…”

“…The literature suggests that the EBR hormone alleviates membrane damage by regulating the activity of antioxidant defence systems, which inhibit the burst in accumulation of toxic ROS. Ghorbani and Pakkish [ 41 ] and Pakkish et al [ 42 ] observed higher catalase (CAT) activity in BR-treated orange (1.5 ppm) and grapes (10 µM), respectively. Aghdam et al [ 40 ] noted that postharvest EBR treatment enhanced the PAL activity of tomato fruit, which was significantly higher than in control fruit, an effect associated with higher membrane integrity and lower EL.…”

“…Exogenous postharvest applications of BRs have been reported to enhance bio-active compounds [ 34 , 35 , 36 , 37 ], delay ripening and senescence [ 35 ], and regulate defence-related enzymic activities, which develop robust defence mechanisms against different physiological disorders [ 34 , 35 , 37 , 38 , 39 ]. The mechanism of BRs further involves (1) the upregulation of membrane protein genes (leading to higher membrane integrity) [ 29 , 31 ], (2) the enhancement of phenylalanine ammonia lyase (PAL) and suppressed polyphenol oxidase (PPO) enzymatic activities, leading to higher phenol and anthocyanins accumulation [ 39 , 40 , 41 , 42 ], and (3) higher arginine pathway activity, leading to higher polyamines and proline accumulation [ 39 , 43 , 44 ], resulting in the improved antioxidant capacity of the crop. Notably, single phytohormone treatment is the main formulation of BRs’ exogenous postharvest applications for the preservation of horticultural crops.…”

This study evaluated the efficacy of chitosan (CH) functionalized with 24-epibrassinolide (EBR) coating in terms of preserving the postharvest quality of late-harvested pomegranate (cv. Wonderful) fruit. Late-harvested pomegranate fruit were immersed for 3 min in different surface treatment solutions—CH 1.5% (w/v), CH + 2 µM EBR, CH + 5 µM EBR, CH + 10 µM EBR and CH + 15 µM EBR—and distilled water was used as a control treatment. The fruit were air-dried and subjected to long storage duration at 5 °C with 85 ± 5 RH for 12 weeks. At 4-week sampling intervals, a batch of fruits was placed at 21 ± 2 °C and 65–70% RH for a further 3 d period to simulate retail conditions before measurements were taken. Fruit physiological responses, physico-chemical properties, phytochemical contents, antioxidant capacity and physiological disorders were monitored during storage. The results showed that the CH-EBR composite edible coatings significantly (p < 0.05) delayed degradative processes due to senescence. The CH-EBR treatments delayed colour, texture and total soluble solids (TSS) degradation and reduced weight loss, respiration, electrolyte leakage and spoilage compared to the control and CH treatment. The treatment effect was more noticeable on fruit treated with CH + 10 µM EBR, which exhibited lower weight loss (18.19%), respiration rate (7.72 mL CO2 kg−1 h−1), electrolyte leakage (27.54%) and decay (12.5%), and maintained higher texture (10.8 N) and TSS (17.67 °Brix) compared to the untreated fruit with respective values of 24.32%, 18.06 mL CO2 kg−1 h−1, 43.15%, 37.5%, 8.32 N and 17.03 °Brix. This was largely attributed to the significantly higher antioxidant content, including the ascorbic acid content, total phenol content, total anthocyanin content and DPPH (radical scavenging activity), of the coated fruit compared to the control fruit. Therefore, CH + 10 µM EBR treatment is recommended as a postharvest management strategy to improve the quality preservation of late-harvested pomegranate fruit during storage.

“…This characteristic, together with the decrease in acidity observed in response to EP24, implies a better and more pleasant flavor of the fruits. The improvement of quality parameters observed in strawberry fruits in response to treatment with BRs, agree with studies reported in other species such as: tomatoes [64], cherries [65], and grapes [66], among others.…”

Brassinosteroid Applications Enhance the Tolerance to Abiotic Stresses, Production and Quality of Strawberry Fruits

et al. 2022

Brassinosteriods (BRs) have increasingly been used to improve the yields and quality of various crops. In this work we studied the effect of two brassinosteroids, BB16 and EP24, on the growth promotion of Fragaria ananassa plants under normal conditions or exposed to water or saline stress. The influence of both BRs on the plant development and fruit quality was evaluated when cultivated in semi-hydroponic conditions. A marked growth-promoting effect was observed with both compounds when plants were cultivated under normal irrigation conditions and under saline and water stresses. BB16 and EP24 yielded plants with a higher dry weight, root length and surface, a higher number and area of leaves, a higher total weight of fruits per plant, and a higher percentage of fruits of commercial quality. Additionally, a higher content of chlorophyll, number of leaves, and increased dry weight was detected in plants treated with both BRs and exposed to water and saline stresses. Finally, when evaluating the production and quality of fruits obtained under semi-hydroponic conditions, we observed that the pre-harvest treatment with both compounds induced a higher fruit production and better quality of fruits. These results suggest the potential of these compounds to achieve a more sustainable management of strawberry cultivation.
