FRUIT QUALITY OF ORTANIQUE TANGOR ON TEN CITRUS ROOTSTOCKS IN THE TADLA REGION, CENTRAL MOROCCO | ..

The effects of ten citrus rootstocks on the fruit quality of Ortanique tangor (C. reticulate x C. sinensis) were investigated in this research, including sour orange, Moroccan Troyer citrange, Moroccan Carrizo citange, Citrumelo 4475, MandarineSunki x Poncirustrifoliata, Citrus macrophylla, Citrus volkameriana, FLhorag an intergeneric, Carrizo citange 28608, and Fruit weight, equatorial and polar diameters, peel thickness, percentage of juice, acidity,Total soluble solids (TSS), Ripening Index, juice pH, vitamin C content, carotenoid content, and fruit colour were among the variables investigated.Fruits with high juice contentwere produced on Citrumelo4475, Citrus volkameriana, Mandarine Sunki x Poncirus trifoliate, and sour orange rootstocks. The trees grafted on the Carrizo citange 28608 had the highest percentage of juice citrate. The highest TSS values were found in fruits harvested from trees grafted on Citrumelo4475, sour orange, and Troyer citrange B2 31655, while the lowest TSS values were found in fruits harvested from Citrus macrophylla and Flhorag. Citrus volkameriana trees were the first to be harvested, followed by Citrus macrophylla.Fruit from trees grafted on the Carrizo citange 28608 and sour orange produced the most acidic juice.
