Two experiments with Navel orange scions (CV. Washington and Leng) on a number of rootstocks were done on three sandy Mallee soils in the Mildura irrigation district. Rootstocks included sweet orange (eight cultivars), rough lemon, mandarin (two cultivars), trifoliate orange, and citrange (two cultivars). In experiment 1 (1949 to 1963) eight sweet orange rootstocks gave similar results in terms of yield and tree size. Leng produced more but smaller fruit than Washington, but total weights were similar. In experiment 2 (1959 to 1969 and continuing) Leng trees were larger, produced more fruit, and on one soil a greater weight of fruit per tree than Washington. Sweet orange rootstocks were usually superior to other rootstocks on each soil type, although rough lemon gave results that were similar and, for a few combinations, superior. Trees on mandarin rootstocks were low producers and small in the early part of the experiment, but by the end of the period were yielding as much fruit as those on sweet orange. Trifoliate rootstocks were unsatisfactory, and citrange intermediate between sweet orange and trifoliate. No fruit quality differences ascribable to rootstock were detected.

Abstract The diversification of scion and rootstock varieties is tremendously necessary for the citrus industry in Northeastern Brazil. The initial performance of 13 sweet orange varieties grafted onto ‘San Diego’ citrandarin, and of ‘Cara-Cara’ navel orange and ‘CNPMF-02 Persian’ lime grafted onto several rootstocks was evaluated in the municipality of Inhambupe, northern coast of the state of Bahia. Three trials were carried out separately, and tree size, fruit production and quality were assessed in the first three crops, with planting in 2008 at 6.0 m x 3.0 m spacing with supplemental irrigation. ‘Aquiri’, ‘Biondo’, ‘Agridoce’, ‘Kona’, ‘Pineapple’, ‘Russas CNPMF-03’ and ‘Salustiana’ sweet oranges showed the largest cumulative production in the first three crops. ‘Pera CNPMF D-6’, ‘Westin CNPMF’ and ‘Salustiana’ sweet oranges had fewer seeds per fruit, being more appropriate for fresh fruit market, in addition to greater production efficiency for the first one. Although ‘Westin CNPMF’ has shown good fruit quality, its initial production was low. ‘Florida’ rough lemon and ‘Volkamer’ lemon induced higher cumulative production compared to ‘Cara Cara’ navel orange, but tree size and fruit quality were not influenced by any evaluated rootstock. ‘Cleopatra’ mandarin and ‘Riverside’ citrandarin led to higher tree size and cumulative production and heavier fruits of ‘CNPMF-02 Persian’ lime. All scion and rootstock combinations have potential for cultivation on the northern coast of the state of Bahia and appear as an alternative to the prevalent ‘Pera’ sweet orange on ‘Rangpur’ lime combination.

Four long-term citrus rootstock trials (navel orange, mandarin, Valencia orange, and lime soil trial) established at Irymple, in the Sunraysia district of Victoria, were tested for leaf nutrient composition in each of 2 years. Scion or rootstock significantly influenced leaf nutrient composition in orange and mandarin trees in all 4 trials. Poncirus trifoliata and citrange rootstocks and Ellendale tangor scion resulted in high to moderate leaf N, P, and K concentrations, while Symons sweet orange rootstock and Dancy mandarin gave low leaf nitrogen (N), phosphorus (P), and potassium (K) concentrations. Potassium concentrations of navel and Valencia oranges on rough lemon rootstock were lower than on most of the other rootstocks tested. For all rootstocks, however, leaf N, P, and K concentrations were in the high range in the navel orange and Valencia orange trials, while leaf K concentrations were in the high range in the mandarin trial. Citrange rootstocks and Ellendale scion also had higher concentrations of leaf magnesium (Mg), while Symons sweet orange, Cox sweet orange, and Rangpur lime had lower leaf Mg concentrations than other rootstocks and scions. In the Valencia rootstock trial, rough lemon and Rangpur lime induced the highest leaf sulfur concentrations, while citrange rootstocks gave the lowest. Soil depth in the lime soil trial influenced foliar P and K levels in Valencia orange trees but these differences were small. In all trials, rootstock, but not scion, strongly influenced chloride (Cl) concentrations of citrus leaves. Poncirus trifoliata rootstock accumulated high concentrations of Cl, and the citrange rootstocks moderate, while Cleopatra mandarin rootstock showed consistently low leaf C1 concentrations in all trials. Rough lemon rootstock was not consistently good at excluding C1, and Rangpur lime showed good C1 exclusion only in the Valencia rootstock trial. There was no evidence of a negative relationship between uptake of N and C1 by citrus rootstocks. Poncirus trifoliata had a lower uptake of sodium (Na) in the Valencia rootstock trial, while Cleopatra and Emperor mandarin rootstocks showed slightly higher leaf Na levels than most other rootstocks tested. The 2 citranges, mandarin, rough lemon, and Rangpur lime rootstocks induced higher boron (B) concentrations in leaves of navel orange compared with other rootstocks but they were still in the adequate range for citrus (Reuter and Robinson 1986), while sweet orange rootstocks had lower levels. Emperor mandarin scion on all rootstocks tested had the lowest B levels. Concentrations of iron and copper were rarely influenced by scion or rootstock. Rootstock significantly influenced leaf manganese (Mn) and zinc (Zn) levels in a number of trials, but scion effects were minor. In comparison with all other rootstocks, rough lemon induced higher Mn levels in some cases; sweet orange rootstocks gave higher leaf Zn levels in other cases; while Rangpur lime induced higher Mn and Zn levels in trees grown in the lime soil trial. In the first 3 trials, concentrations of Zn and Mn were low in many of the rootstocks and scions, indicating a need for a second micronutrient spray per growing season.

Abstract The objective of this work was to evaluate tree size, production, and fruit quality of ‘Valência’ sweet orange (Citrus sinensis) grafted on various trifoliate orange rootstocks, in order to select genotypes with a high performance. Twenty rootstock genotypes were evaluated, including trifoliate orange hybrids with mandarin (citrandarins) and with grapefruit (citrumelos), as well as ‘Rangpur’ lime. The experiment was implemented in the northwestern region of the state of Paraná, Brazil, in a 6.0×2.5 m spacing, in a sandy soil under subtropical and rainfed conditions. The statistical model used was the randomized complete block design with four replicates and four trees per plot. Tree size and fruit yield and quality were analyzed during three consecutive harvest seasons. Data were subjected to the analysis of variance, and means were grouped by the Scott-Knott test. Principal component analysis and agglomerative hierarchical clustering were also carried out. F.80-18, F.80-5, and F.80-3 citrumelos and IPEACS-239 citrandarin are adequate rootstock options for ‘Valência’ sweet orange, with dwarf trees and a high production efficiency. These rootstocks, except F.80-18, are also adequate options to obtain oranges with good industrial properties.

Juice Content

The causes of poor fruit quality, particularly high acid content, of oranges in the Murrumbidgee Irrigation Areas (M.I.A.) were investigated. In a two year sand culture experiment, using Washington Navel orange cuttings, the fruit quality factor most affected by potassium nutrition was juice acidity, with low K levels resulting in low acidity, and thinner peel, In the second season the no potassium treatment also had some adverse effects on fruit quality. Regression analyses on data obtained from a long term citrus experiment showed that high leaf potassium was associated with high acidity in Washington Navel, and with low juice content, high acidity and thick peel in Late Valencia. High leaf P was associated with high juice content, low acidity, thin peel and, for Late Valencia, low sugar content also. Data obtained from Washington Navel fruit taken from nine farms in the M.I.A. were subjected to regression analyses. Rootstocks were rough lemon (eight farms) and sweet orange (one farm). Mineral contents of leaves and juice were correlated, but juice contents were more strongly correlated with quality. High levels of K in the juice were associated with high acidity, while high P levels were correlated with low acidity. High levels of P were associated with high juice content.

Significant Difference

Growth, yield, and fruit quality were recorded for Ortanique tangor (Citrus reticulata Blanco) on 11 rootstocks until the trees were 12 years old. Trees on Volkameriana (C. volkameriana Pasq.), rough lemon, and `Estes rough lemon (C. jambhiri Lush.) were more productive per unit of tree size, and their cumulative yields per tree were significantly higher than those of trees on the other rootstocks. There was no significant difference between cumulative yields of Ortanique on the following rootstocks: sour orange (C. aurantium L.), `Palestine' sweet lime (C. limettioides Tan.), `Red' rough lemon (C. jambhiri Lush.), Rangpur (C. limonia Osbeck), and Amblycarpa (C. limonellus var. amblycarpa Hassk.). However, yield on these rootstocks was significantly higher than on Carrizo and Troyer citranges [C. sinensis (L.) Osbeck × Poncirus trifoliata (L.) Raf.] and `Swingle' citrumelo [C. paradisi Macf. × P. trifoliata (L.) Raf.]. The high productivity per unit of tree size of `Palestine' sweet lime suggested that this rootstock could be used advantageously in closely spaced plantings. Rootstocks affected fruit size, weight, rind thickness, juice content, total soluble solids concentration (SSC), and total acids, but the differences were not large enough to be of practical importance.

Some viroids reduce citrus tree growth and may be used for tree size control aiming the establishment of orchards with close tree spacing that may provide higher productivity than conventional ones. To study the effects of citrus viroids inoculation on vegetative growth, yield and fruit quality of 'Marsh Seedless' grapefruit (Citrus paradisi Macf.) grafted on trifoliate orange [Poncirus trifoliata (L.) Raf.], an experiment was set up in January 1991, in Bebedouro, São Paulo State, Brazil. The experimental design was randomized blocks with four treatments with two plants per plot: viroid isolates Citrus Exocortis Viroid (CEVd) + Hop stunt viroid (HSVd - CVd-II, a non cachexia variant) + Citrus III viroid (CVd-III) and Hop stunt viroid (HSVd - CVd-II, a non cachexia variant) + Citrus III viroid (CVd-III) and controls: two healthy buds (control), and no grafting (absolute control). Inoculation was done in the field, six months after planting by bud grafting. Both isolates reduced tree growth (trunk diameter, plant height, canopy diameter and volume). Trees not inoculated yielded better (average of eleven harvests) than inoculated ones but the productivity was the same after 150 months. Fruit quality was affected by viroids inoculation but not in a restrictive way. The use of such severe dwarfing isolates for high density plantings of grapefruit on trifoliate orange rootstock is not recommended.

The influence of 5 rootstocks (Parramatta sweet orange, trifoliate orange, Troyer citrange, Appleby Smooth Seville and Somersby Smooth Seville) on the productivity and fruit quality of Marsh and Davis grapefruit was studied over 15 years in the Lower Murray region of New South Wales. Annual yields of mature trees and cumulative yield were highest on Troyer citrange; cumulative yield was lowest on trifoliate orange. Canopy volume was largest on Troyer citrange and smallest on trifoliate orange. Production efficiency (fruit yield per unit of tree size) was significantly greater on trifoliate orange than all other rootstocks. Canopy volume was 44% smaller on trifoliate orange than on Troyer citrange, but cumulative yield was only 26% lower. Because of their small size and high production efficiency, trees on trifoliate orange would be suitable for high density plantings. Trifoliate orange produced the best quality fruit. Fruit from trees on trifoliate orange had the highest total soluble solids (TSS) and TSS :acid ratio. Sweet orange and Appleby Smooth Seville produced the least acceptable fruit due to low TSS :acid ratios. Fruit size was largest on Troyer citrange and trifoliate orange. Trees on trifoliate orange accumulated excessive chloride (Cl-) during periods of high irrigation water salinity; however, no adverse effects on growth or long-term productivity were apparent. Leaf C1- concentrations for trifoliate orange varied from 0.42 to 1.10%. Leaf C1- concentrations remained below 0.30% for the other rootstocks. There were no significant effects of scion cultivar on tree size, yield or production efficiency, and differences in fruit quality were slight. Fruit size was larger with Marsh than Davis.

AbstractA total of 145 accessions of the genus Citrus and related genera, maintained in the Conservation Garden for Citrus Germplasm at the Experimental Farm of Kindai University, Yuasa, Wakayama, Japan, were examined for their phylogenetic relationships. The present classification was conducted using an inter-retrotransposon amplified polymorphism (IRAP) method based on the insertion polymorphism of a retrotransposon, CIRE1, identified in C. sinensis. The objective of this study was to evaluate the applicability of the IRAP method for citrus classification. The constructed dendrogram showed that the 145 accessions and two outgroup species were successfully classified into five major clades. A large number of C. sinensis accessions were divided into three traditional groups, navel orange, sweet orange, and blood orange, almost corresponding to the sub-clades in the dendrogram. Several other accessions belonging to the same species, and also many hybrid cultivars from crossbreeding, were localized into the respective sub-clades or near positions in the dendrogram. Several unclassified accessions could also be located in the dendrogram, suggesting novel relationships with other accessions. It was concluded that the IRAP method based on CIRE1 insertion polymorphism was suitable for the classification of citrus from a molecular point of view.

Washington navel orange trees on trifoliate orange rootstocks were inoculated at various ages with budwood from either severely dwarfed Washington navel trees with butt scaling caused by exocortis virus or moderately dwarfed Marsh grapefruit trees with no butt scaling. Dwarfing, measured by trunk girth, became apparent four seasons after inoculation, the butt scaling inoculum causing more pronounced dwarfing than the non-scaling inoculum. For both inocula, trees inoculated in the nursery were the most dwarfed, and yielded least, with trees inoculated in the field one, two, three or five years later being successively less dwarfed and high yielding. In a second experiment, Washington navel orange trees on trifoliate orange, which were carrying exocortis virus or were inoculated with it either in the nursery or later in the field, were planted in 1962 at a density of 835 ha-1. The field inoculated trees subsequently grew larger than the others. All were more dwarfed but yielded more heavily on a ground area basis during five years of cropping than exocortis-free trees planted at a normal density of 222 ha-1. Dwarfed trees developed butt scaling symptoms and periodically became unthrifty. The non-scaling form of dwarfing lends itself to the development of high density plantings of small trees with consequent benefits in management and high early production
