El cultivo de cítricos es una actividad muy importante en la industria frutícola nacional. Los que se cultivan México son: Citrus sinensis L. naranja, aurantifolia limón mexicano, latifolia persa, paradisi pomelo y reticulata mandarina (SIACON, 2006). La fruta está disponible casi todo el año, con disponibilidad más baja septiembre. De junio a septiembre, Veracruz abastece al mercado nacional, ...

Dwarfing rootstocks are a valuable genetic resource for managing high-density plantations. The selection of the appropriate scion/rootstock combination is key to improving crop performance and sustainable production in particular environment specific training systems. ‘Shatangju’ mandarin scion cultivar grafted onto ‘Flying Dragon’ rootstock tends be dwarfing develops short stature plants. To o...

Chilling temperatures (below 10' but above the freezing point of the tissue) injure fruits of coldsensitive crops native to tropical and subtropical areas (1,4, 5). Sweet orange (Citrus sinensis Osb.) fruits, even though mature internally, may not lose their chlorophyll on the trees when grown in tropical climates. However, oranges grown on the northern fringes of the sutbtropical regions of Fl...

Kinnow (Citrus reticulata Blanco) mandarin is a superior fruit crop in Pakistan; however, it is characterized by high number of seeds which is disliked by consumers and the processing industry. The objective of this work was to document the morphological and genetic differences in selected seeded and seedless Kinnow strains from two different locations i.e., Citrus Research Institute Sargodha a...

In this study, 3 mm thick quince slices were dipped in bitter orange (BO), tangerine (Citrus deliciosa Mediterranean) (CDM), (O), reticulata Owari) (CRO), pomegranate (P) juices and a non-pre-treatment (control) dried at an air temperature of 70 °C velocity 1.5 m/s. According to the results pre-treatment trials, drying time was found be minimum 121 min 5 dipping reach safe moisture content 10% ...

Environ.Enlomol.17(4): 715-721 (1988) ABSTRACT The suitability of lemon, Citrus limon (L.) Burm. cv. Lisbon, for egg production by the citrus red mite, Panonychus citri (McGregor), was compared with that of mandarin orange, Citrus unshiu Markovitch cv. Satsuma in the field and laboratory over a 15-moperiod. The two plant specieswere most suitable during the spring (April-June), when mites gener...

Satsuma mandarin, Citrus unshiu Marcovitch, has been grown for over a century in the Gulf Coast region of the United States (English and Turnipseed 1940). However, the last decade has recorded a major increase in the production of this crop in southern Alabama, fuelled by improved production and tree protection methods and strong industry and state support (Campbell et al. 2004). Studies have i...

Dried citrus peels (Chimpi) is one of the most common natural medicines with qi (energy flow) rectifying and shi (dampness) drying actions, which originates from Citrus unshiu, and/or C. reticulata according to the definition of the pharmacopoeiae of Japan and China. In this study, the pharmacological effects of their extracts and major chemical constituents hesperidin and its aglycone hesperet...

Effects of girdling on carbohydrate status and carbohydrate-related gene expression in citrus trees were investigated. Alternate-bearing 'Murcott' (a Citrus reticulata hybrid of unknown origin) trees were girdled during autumn (25 Sep. 2001) and examined 10 weeks later. Girdling brought about carbohydrate (soluble sugar and starch) accumulation in leaves and shoot bark above the girdle, in tree...
