study the effect of some treatments shows that sunburned berries % was significantly reduced with spraying Kaolin at 4 %, Purshade at 4%, Screen Duo at 12 cm 3 /L, GA3 at 10 ppm+ 2 % Urea was investigated on the control of sunburn effects, berry temperature and yield quality of red globe grapevines grown under the Egyptian hot conditions during 2019 and 2020 seasons. The vines received three sprays of Kaolin, purshade and Screen Duo at (first-June, mid-June and mid-July), while GA3 and Urea were sprayed twice at two weeks after fruit setting and 30 days later for both seasons. Results showed that all treatments reduced berry temperature. The application of Screen Duo surpassed the application of Kaolin, Purshade and GA3 plus Urea in this respect as it was one of the most effective techniques in controlling. However, spraying in all treatments effectively reduced sunburned berries %, total acidity and improved yield quality, cluster weight, total soluble solids, anthocyanin and reducing sugar. Treatment with Screen Duo at 12 cm 3 /L+ GA3 at 10 ppm+ 2 % Urea gave the best results concerning Growth parameters, yield, cluster weight, cluster length, cluster width, sunburns and some physical and chemical properties of berries grapes. Control treatment gave the lowest value concerning all parameters in two seasons.

Kaolin Improves Photosynthetic Pigments, and Antioxidant Content, and Decreases Sunburn of Mangoes: Field Study

et al. 2022

The Keitt mango tree has a low canopy that leads to an increase in sunburned fruits. Hence, the fruit quality is markedly reduced due to the fruit being exposed to physiological disorders. The sunburn injury problem is common due to high levels of solar radiation and the low number of leaves, which minimizes the protection of small, newly formed fruits. Kaolin spray has emerged as a promising approach for mango trees since it improves vegetative growth, yield, and fruit quality in new lands. This search aimed to study the influence of spraying kaolin on Keitt mango trees grafted on ‘Succary’ rootstock. The treatments were as follows: control, 2%, 4%, and 6% of kaolin. Our results indicated that the applications of kaolin significantly improved leaf area, tree canopy volume, photosynthesis pigments such as chlorophyll-a and b, carotenoids of leaf and yield (kg/tree), and the physical and chemical characteristics of Keitt mango cultivar in comparison with the control. A higher concentration of kaolin decreased the leaf content of antioxidants such as total phenolic, total flavonoid, CAT, POX, and PPO enzyme activities. Furthermore, the number of sunburned fruits was significantly reduced after the application of kaolin in comparison to control fruits. Regarding vegetative growth, our results indicated that adding kaolin at 6% enhanced the leaf surface area and tree canopy volume compared to the control and other treatments. A similar trend was noticed regarding yield and fruit quality, whereas the best values were obtained when kaolin was sprayed at a concentration of 6%. In conclusion, the application of kaolin can improve the production and fruit quality of Keitt mango trees by reducing the effects of adverse summer conditions.

“…To mitigate such a problem, studies were done with crops of economic importance, such as apple (ALDEBENITO-SANHUEZA et al 2016; RACSKO; SCHRADER 2012), pineapple (LOPES et al 2014), pomegranates (SHARMA et al 2018) and pears (COLAVITA et al 2011). For mangoes, despite its economic importance, few works are issuing this problem, except one recommending wool-lined plastic caps (SILIMELA;KORSTEN 2005) and other, more recently, comparing kaolin and Screen Duo® coatings in a field study with Keitt mango (BAIEA et al 2018). In general, the sunburn prevention is based on suppressing techniques such as shade nets, fruit bagging and particle films, e.g., kaolin clay (RACSKO; SCHRADER 2012).…”

Sunburn is responsible for significant losses in post-harvest and has motivated studies to diminish its effect on different types of cultivars. Thus, the present study proposes a rapid protocol to evaluate the photoprotective effect of suppressive formulations. The experiment consisted in placing fruits (mango) covered with different suppressor formulations about 7 centimeters from an incandescent source and measuring the surface temperature variation employing a thermometer and thermal camera. The formulations were based on a filmogenic polysaccharide (galactomannan) and reflective additives (hydroxyapatite, montmorillonite and bentonite clays). The best result was achieved with a coating with bentonite as an additive, which showed a statistical difference in temperature (43.3±2.1 °C) compared with the control (52.1±3.0 °C) and the standard kaolinite coating (39.4±1.7 °C). Thus, it was proven the viability of the protocol as well as of the alternative formulations in to reduce the sunburn effect. This contributes to solution for the establishment of the Tropical Agriculture.
