“…According to Thanaa et al [63], foliar spraying with 6% MLE resulted in higher lightness (L*) and hue angle (h • ) value of plum fruit, which was likely due to the increased enzyme activity and anthocyanin content by the MLE application, leading to the formation of more colored fruit. These results are in agreement with the findings by Mahmoud et al [61], who found an increase of L* in Hollywood plum cultivar.…”

“…A similar conclusion was found by Abo El-Enien et al [60], i.e., foliar spraying of MLE significantly enhanced fruit firmness of the navel orange. The application of 10% MLE together with 2% B and 3% Ca improved the firmness of plum fruit [61]. Moreover, Ismail and Ganzour [22] reported an increment in fruit firmness of strawberries after spraying solely with MLE or in combination with KNO 3 .…”

Ensuring high-quality agricultural products has become important in agriculture since society’s standard of living has risen. Meanwhile, Moringa oleifera L. leaf extract (MLE) has been used as a plant biostimulant to improve product quality. The effectiveness of MLE is associated with its beneficial components, consisting of nutrients, phytohormones, secondary metabolites, amino acids, and bioactive compounds. Previous studies have been carried out to find the effects of MLE application on the quality of different crops, including basil, kale, spinach, maize, radish, brinjal, pepper, tomato, grape, strawberry, and more. The results are generally positive concerning physical, nutritional, and chemical qualities. This review comprises recent findings regarding MLE application as a plant biostimulant to increase quality attributes, with its underlying mechanism.

“…Total phenolic content (TPC, mg GAE/kg) continuously increased in the fruits treated with oils until 9 days from the start of the storage period, at which point the trend slowed down gradually and peaked on day 18. Mahmoud et al [73] found that the TPC of the Hollywood plum was increased during cold storage. Piljac-Žegarac and Šamec [74] reported that small fruits like strawberries, raspberries, cherries and sour cherries stored at 4 • C exhibited slightly higher antioxidant activity values.…”

Post-Harvest Enhancing and Botrytis cinerea Control of Strawberry Fruits Using Low Cost and Eco-Friendly Natural Oils

et al. 2021

This work investigates an experimental study for using low-cost and eco-friendly oils to increase the shelf life of strawberry fruit. Three natural oils were used: (i) Eucalyptus camaldulensis var obtuse, (ii) Mentha piperita green aerial parts essential oils (EOs), and (iii) Moringa oleifera seeds n-hexane fixed oil (FO). Furthermore, a mixture of EOs from E. camaldulensis var obtusa and M. piperita (1/1 v/v) was used. The treated fruits were stored at 5 °C and 90% relative humidity (RH) for 18 days. HPLC was used to analyse the changes in phenolic compounds during the storage periods. The effects of biofumigation through a slow-release diffuser of EOs (E. camaldulensis var obtusa and M. piperita), or by coating with M. oleifera FO, were evaluated in terms of control of post-harvest visual and chemical quality of strawberry fruits. The post-harvest resistance of strawberry fruits to Botrytis cinerea fungal infection was also evaluated. As a result, the EO treatments significantly reduced the change in visual and chemical quality of strawberry fruit. Additionally, changes in the titratable acidity of moringa FO-coated strawberry fruits were delayed. EO treatments improved total soluble solids, total phenols, ascorbic acid, antioxidants and peroxidase. E. camaldulensis var obtusa and M. piperita (1/1 v/v) EO-vapour fruit exhibited a slower rate of deterioration, compared to other treatments in all tested, in two experiments. The lowest colour change (ΔE) was observed inthe fruit treated with E. camaldulensis var obtusa EO and M. oleifera FO. HPLC showed changes in phenolic compounds’ concentration, where p-coumaric acid, caffeic acid, gallic acid, ferulic acid and ellagic acid were mostly identified in the fruits treated with the oils. SEM examination confirmed the potential decrease in fungal growth as the fruits were treated with EOs. In conclusion, the treatment of EOs during different storage periods showed promising characterisations for strawberry fruit quality.

“…Results on color attributes of fruit peels showed that plants treated with foliar MLE at 1:20 had higher L* values (37.54) compared to the control. Thanaa et al [61] and Mahmoud et al [62] found similar results when using pre-harvest MLE treatment on L* in plum fruit. Meanwhile, our study revealed that a* and b* values were negatively influenced by the treatments.…”

Assessment of Biostimulant Derived from Moringa Leaf Extract on Growth, Physiology, Yield, and Quality of Green Chili Pepper

et al. 2023

With the rapid growth in global population and standards of living, improving food production and quality are the greatest challenges in agriculture. The application of biostimulant derived from moringa leaf extract (MLE) has attracted a great deal of interest to support these efforts in a sustainable approach. A field study was conducted using a randomized complete block design with four replications. The effect of individual and combined application of MLE through seed priming (seed soaking) and foliar spray at different rates (1:30, 1:20, and 1:10, v/v) on growth, physiological, yield, and quality traits of green chili pepper were investigated, which was the aim of this study. In general, the responses generated by the combined MLE methods were more pronounced compared to their single applications. Among all treatments, MLE priming plus foliar spray at 1:30 was effective in improving most traits observed, including chlorophyll fluorescence (6.49%), stomatal conductance (57.19%), plant height (30.57%), leaf number (88.89%), leaf area index (116.67%), fruit weight per plant (46.27%), average fruit weight (39.62%), length (9.89%), diameter (29.65%), firmness (27.77%), and vitamin C content (29.07%) of fruit. Therefore, it is regarded as an appropriate treatment to maximize the potential use of MLE in green chili.
