22 23 2 SUMMARY 23 Citrus exocortis viroid (CEVd) populations are composed by closely related 24 haplotypes whose frequencies in the population result from the equilibrium 25 between mutation, selection and genetic drift. The genetic diversity of CEVd 26 populations infecting different citrus hosts was studied by comparing 27 populations recovered from infected trifoliate orange and sour orange...

citrus is one of the most important fruit crops in iran. among the citriculture areas of iran, mazandaran province has the highest acreage (about 100,000 ha), production and number of varieties nationwide. unauthorized importation of citrus species and cultivars and propagation by growers and nurserymen have led to perpetuation and spread of virus, viroid and other graft-transmissible pathogens...

gummy bark disease of sweet orange (citrus sinensis) trees has been reported from a few citrus growing regions of the world. the disease symptoms consist of mild to severe stem pitting and brown gummy flecks in the bark of sweet orange trees on sour orange ( c. aurantium) rootstock, being conspicuous several centimeter above the bud :union: on the trunk. the pits were usually impregnated with b...

Fruit peels of Banana, Pomegranate, Sweet lime and Orange are highly rich in potash, ion, Zinc etc. Above fruit peels powder were formulated from the trace amounts and gradually increased for the preparation of three formulations as Formulation 1, Formulation 2 and Formulation 3. Three different formulations were applied for plant growth in two methods such as fruit peel powder, fruit peel powd...

sour cherry and orange juice were successfully cryoconcentrated. novel clarification (electro-flotation and ultra-filtration) improved cryconcentration efficiency. ef-uf clarified sour cherry and orange juices were cryoconcentrated in three stages up to 34.52±0.14, 44.42±0.19, 52.44±0.13 and 28.43±0.16, 40.51±0.15, and 45.42±0.19° brix at -10˚c respectively. duncan's multiple range test was use...

the turbidity of sour orange juice after juice extraction affects on quality, shelf-life and concentration of juice. therefore, juice clarification is an important operation in the fruit processing industry. the goal of this study was evaluating the effect of membrane operation parameters including pressure (120-220 kpa) and temperature (25-35 ºc) on the permeate flux and hydraulic resistance o...

effect of different ratios of sucrose to fruit concentrate (orange and sour cherry), level of cacl2 (0-2%) and storage time (0-90 days) on physicochemical properties of candied apples were investigated using of a combined design. different quality indices such as total sugars content, ascorbic acid, color attribute (chroma) and overall acceptance were modeled and then multiobjective optimizatio...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

Sour oranges (Citrus aurantium L.) are well known in the processing and cosmetics industries for aromatic properties of their essential oils. Intercultivar genetic diversity is not documented. The objective this study was to evaluate impact morphological selection mechanisms varietal diversification (mutation or hybridization) on odor variability sour orange Forty-five accessions from INRAE-CIR...

the production of reactive oxygen species (ros) in plants under low temperature stress cause damage to plants. in order to evaluate of antioxidant responses of page mandarin young trees (two years old) on different rootstocks under low temperatures, an experiment was conducted in a factorial plan based on completely randomized design. treatment of temperatures were at seven levels include 9, 6,...
