One such Research Program on Mandarins <\/strong>was carried out in Chania, Crete, in collaboration with the Institute of Olive Tree, Subtropical Plants and Viticulture, ELGO\u2014DIMITRA.<\/p>\n\n\n\n

The field was divided into two equal plots, one was used as Control, while Agrology\u2019s Program was applied to the other plot. In both plots, the farmer used the same plant protection and plant nutrition-fertilization program, apart from the additional applications with Agrology\u2019s Functional Crop Nutrition\u00ae<\/em><\/strong> products, in this case Gravital Force SC, aiming to Mandarin Quality Characteristics Improvement.<\/p>\n\n\n\n

    The Role of Silicium<\/strong><\/h2>\n\n\n\n

    Silicium (Si) is regarded as a highly significant element in plant nutrition and is classified among biostimulants. It positively impacts plant tissue structure and enhances resilience to abiotic stress. Its influence on fruit quality is of particular interest to producers, especially when applied foliarly. This study investigates the postharvest behavior of mandarin fruits treated with a silicium-calcium formulation (Gravital\u00ae Force SC, 35% SiO\u2082 & 35% CaO w\/w), applied as a concentrated suspension (SC) at a dosage of 250cc\/100L.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    Experimental Design<\/strong><\/strong><\/h2>\n\n\n\n

    This study focused on the postharvest response of mandarin fruits (cv. Clementine SRA 63) following foliar treatment with a Si-Ca formulation. Three foliar sprays were performed (late August, late September, and late November). The fruits were harvested at full maturity, stored in a cold chamber (4\u00b0C, 90% RH) for one month, and then kept at room temperature. Measurements were taken at harvest day and on days 0, 3, and 5 of shelf life.<\/p>\n\n\n\n

    \n
    \"Increase<\/a><\/figure><\/div>\n\n\n

    The foliar application of the Si-Ca formulation resulted in an increase in total soluble solids (Figure 4) and citric acid concentration (Figure 5), while it reduced the SSC-to-acid ratio (Figure 6), both at harvest and during the fruits\u2019 shelf life, imparting a more pleasant and well-balanced flavor.<\/p>\n\n\n\n

    \n
    \"Preservation<\/a><\/figure><\/div>\n\n\n

    The application of the Si-Ca formulation enhanced the phenolic content (Figure 7) and antioxidant capacity (Figure 8) of the mandarin fruits, both at harvest and during shelf life. It also enabled the fruits to retain high levels of ascorbic acid after cold storage (Figure 9). Furthermore, the use of the Si-Ca treatment significantly reduced Penicillium<\/em> infection on the 3rd and 5th day of shelf life (Figure 10).<\/p>\n\n\n\n

    Overall, the foliar application of the Si-Ca formulation, Gravital\u00ae Force SC, substantially improves the postharvest quality of Clementine mandarin fruits.<\/p>\n\n\n

    \u201cThis experiment was conducted under specific field conditions and should not be applied as a standard without the guidance of an Agronomist or the Agrology Technical Department.
