Abstract: The objective of this work was to select rootstocks, based on the agronomic characters and fruit quality of the 'Valência' orange tree. The evaluated rootstocks were: the 'Cleópatra' mandarin; the TSKFL x CTTR-013, LVK x LCR-038, TSKC x CTQT 1439-004, LVK x LVA-009, TSK x TRENG-256 ('Indio' citrandarin) hybrid genotypes; the 'Santa Cruz' Rangpur lime; and the TSKFL x CTC-25-002, and TSKC x CTSW-038 hybrids. The experiment was installed in 2010 and evaluated from 2013 to 2017. The parameters plant height, canopy volume, yield efficiency, scion:rootstock ratio, survival percentage, and drought tolerance were evaluated in 2017. The yield average of five harvests was estimated, as well as the annual production per plant and the accumulated production. The analyzed fruit traits were: mass, diameter, peel length and thickness, juice yield, soluble solids, acidity, and technological index. 'Valência' shows a lower plant height and canopy volume, besides a higher yield efficiency, when grafted on TSKC x CTSW-038 than on the other rootstocks. LVK x LCR-038, TSKC x CTQT 1439-004, 'Indio' citrandarin, and 'Santa Cruz' Rangpur lime increase the production of the 'Valência' orange. LVK x LCR-038 and the 'Indio' citrandarin induce the scion to produce a better quality fruit.

ABSTRACT The aim of this study was to evaluate 12 rootstock varieties on the development and quality of ‘Tahiti’ acid lime fruits cultivated in the municipality of Jaíba, MG. Seedlings were planted in an experimental orchard in November 2008, using 8 x 5 meters spacing and drip irrigation. The experiment was conducted using a scion cultivar (Tahiti acid lime, IAC-5 cultivar) and the following 12 rootstocks: ‘Rangpur’ lime, ‘Troyer’ citrange, ‘Carrizo’ citrange, 1707 hybrid (Rangpur lime x Swingle trifoliate), 1710 and 1697 citrandarins, 1708citradia, ‘Swingle’ citrumelo, ‘Cleopatra’ and ‘Sunki’ mandarins, ‘Volkamer’ lemon, and ‘Limeira’ trifoliate. A randomized block design with five replicates and three trees per plot was used. Trunk diameter of both rootstock and scion, as well as height, diameter, and canopy volume, yield, fruit mass, number of fruits per tree, productivity, production efficiency index, longitudinal diameter, equatorial diameter, total soluble solids, total acidity, and vitamin C content of fruits were evaluated. ‘Volkameriano’ and ‘Cleopatra’ rootstocks promoted higher plant vigor and productivity for ‘Tahiti’ acid lime. However, ‘Limeira’ trifoliate and ‘Troyer’ citrange produced less vigor, but increased production efficiency; and can be used as alternative rootstocks for ‘Rangpur’ lime, as long as adjustments are performed in the planting spacing to increase productivity. In general, no differences in physical and chemical characteristics of fruits for all treatments were found, and fruits remained within commercial standards.

ABSTRACT In the State of Bahia, Brazil, the citrus industry is located on the north coast with the prevalence of the combination ‘Pera’ sweet orange on ‘Rangpur’ lime. Scion-rootstock diversification may contribute to the increase of yield and the extension of harvest season, as long as to decrease the risk associated to abiotic and biotic stresses. Therefore, the performance of ‘Tuxpan Valencia’ sweet orange grafted onto 14 rootstocks was evaluated in Rio Real – BA. Planting was performed in 2006 under rainfed cultivation on cohesive ultisol and tree spacing of 6.0 m x 4.0 m. Tree size, yield and fruit quality were evaluated in the period of 2010-2014, in addition to tree survival at nine years old and drought tolerance in the field based on leaf wilting. In the evaluated conditions, ‘Sunki Tropical’ and ‘Sunki Maravilha’ mandarins led to the highest scion canopy volume. The highest accumulated yield in five harvests was recorded on ‘Santa Cruz Rangpur’ lime, ‘Volkamer’ lemon, ‘Riverside’ and ‘Indio’ citrandarins, ‘Sunki Tropical’ mandarin and the hybrid TSKC x (LCR x TR) – 001. ‘Riverside’ and TSKFL x CTSW – 049 induced higher yield efficiency on the canopy. The rootstocks did not influence the tree survival nine years after planting except for lower survival of TSKFL x CTSW – 049. Drought tolerance was not affected either. Regarding to the fruit quality of ‘Tuxpan Valencia’, the rootstocks influenced the juice content, soluble solids and technological index with the citrandarins, ‘Santa Cruz Rangpur’ lime, ‘Volkamer’ lemon and ‘Sunki Tropical’ mandarin presenting higher performance in general.

Abstract The cultivation of orange trees in Amazonas, Brazil relies predominantly on grafted plants combining ‘Pera’ scion and ‘Rangpur’ lime rootstock. Alternative rootstocks better adapted to the conditions of the region have not been investigated. Therefore, the objective of this research was to test seven rootstocks for the production of high-quality oranges under the typical conditions of the Amazon. Citrus production was evaluated from May to August between 2017 and 2019, based on the variables of cumulative yield, yield efficiency, and crop-yield index over the study period. The fruit physicochemical quality was evaluated by quantification of total soluble solids, total titratable acidity, ratio, juice percentage, and technological index. ‘Indio,’ ‘BRS Bravo’, and ‘Riverside’ genotypes combined with ‘Pera’/CNPMF scion had the highest yield and good fruit quality. They are potentially the most suitable combinations to grow sweet oranges in the Amazon.

The majority of citrus trees in Brazil are grafted on 'Rangpur lime' (Citrus limonia Osb.) rootstock. Despite its good horticultural performance, search for disease tolerant rootstock varieties to improve yield and longevity of citrus groves has increased. The objective of this work was to evaluate yield efficiency of sweet oranges on different rootstocks fertilized with N, P, and potassium. Tree growth was affected by rootstock varieties; trees on 'Swingle' citrumelo [Poncirus trifoliata (L.) Raf. × C. paradisi Macf.] presented the smallest canopy (13.3 m³ in the fifth year after tree planting) compared to those on 'Rangpur lime' and 'Cleopatra' mandarin [C. reshni (Hayata) hort. ex Tanaka] grown on the same grove. Although it was observed an overall positive relationship between canopy volume and fruit yield (R² = 0.95**), yield efficiency (kg m-3) was affected by rootstocks, which demonstrated 'Rangpur lime' superiority in relation to Cleopatra. Growth of citrus trees younger than 5-yr-old might be improved by K fertilization rates greater than currently recommended in Brazil, in soils with low K and subjected to nutrient leaching losses.

In a field experiment, to identify the best sweet cherry varieties for high density orcharding, maximum canopy volume (18.94 cm3) was recorded in variety ‘Steela’ and minimum in ‘Lambert’ while, ‘Bigarreau Napoleon’ had maximum TCSA (213 cm2). Trees grown under HDP have lower TCSA in comparison to normal density. Primary and secondary branch girth were maximum in ‘Bigarreau Napoleon’ whereas, annual extension growth and shoot thickness were high in ‘Steela’. Yield, yield efficiency and cumulative yield efficiency were registered maximum in ‘Bigarreau Napoleon’ and ‘Bigarreau Noir Grossa’ cultivars. Largest fruit weight, fruit length and fruit diameter were found maximum (10.16 g/fruit), (25.51 mm) (25.20 mm) respectively in ‘Bigarreau Napoleon’. Total soluble solids were found maximum in ‘Bigarreau Noir Grossa’ (17.30 0Brix) among the studied cultivars. Correlation matrix showed that TCSA had positive correlation with canopy volume, primary branch girth and secondary branch girth and fruit weight showed positive correlation with fruit length and fruit diameter.

<p>La lima ácida Tahití, <em>Citrus latifolia </em>Tanaka (Rutaceae), es susceptible al daño del virus de la tristeza de los cítricos (CTV), lo que disminuye la rentabilidad del cultivo. En la terraza alta del piedemonte de Meta, Colombia, se evaluó la influencia del virus sobre el comportamiento de la lima ácida Tahití en seis patrones: Carrizo, Sunki × English, Sunki × Jacobson, Pomeroy, Rubidoux y Kryder 15-3. El diseño experimental utilizado fue completa­mente al azar tomando cada árbol como unidad expe­rimental; se utilizó comparación de medias y estadística inferencial para: altura de la planta, diámetro y altura de la copa, volumen de la copa, producción y severidad del virus de la tristeza. La mayor producción acumulada por árbol (kg/árbol) la obtuvo Sunki × English; todos los patrones presentaron una altura homogénea, excepto Carrizo con menor tamaño y volumen de copa. La mayor producción de frutos acumulada durante ocho cosechas se obtuvo con Sunki × English seguido por Rubidoux y Carrizo. La mayor eficiencia productiva promedia se obtuvo con Sunki × Jacobson. La produc­ción y el crecimiento morfológico decayeron en la sép­tima cosecha (2007) en todos los patrones, ocasionado por la infección de una mezcla de aislados de virus de la tris­teza de los cítricos tipo Madeira y tipo B128 que oca­sionan acanalamiento del tallo; tipo B31 que produce acanalamiento moderado; y aislamientos B7 y VT.</p><p><strong>Citrus tristeza virus (CTV) influence on the behavior of Tahiti lime (<em>Citrus latifolia </em>Tanaka) grafted on six rootstocks in the plain piedmont of Colombia (1997-2008)</strong></p><p><strong> </strong>Tahiti lime, <em>Citrus latifolia </em>Tanaka (Rutaceae), is susceptible to Citrus Tristeza Virus (CTV), and if affected, decreases the profitability of the crop. In the well-drained high terrace of the Meta piedmont, the influence of the virus attack was evaluated on the performance of Tahiti lime grafted on six rootstocks (Carrizo; Sunki × English; Sunki × Jacobson; Pomeroy; Rubidoux, y Kryder 15-3) on a completely randomized experiment design taking each tree as an experimental unit. A comparison of means and inferential statistic were used for: plant height, height and canopy diameter; canopy volume, yield and severity of CTV. All rootstocks showed homogenous height. Carrizo was the exception with less size and canopy volume. The highest accumulated fruit yield (Kg/tree) was obtained by Sunki x English, followed by Rubidoux and the lowest yield was obtained by Carrizo. The highest yield efficiency of average canopy volume was obtained with Sunki x Jacobson. The Tahiti lime yield and morphological development fell in the seventh year (2007) in all rootstocks, due to an infection caused by a mix of isolates of CTV type Madeira and type B128, isolates which cause stem channeling: type B31 which causes moderate stem channeling and B7 and VT isolate.</p>

A field planting of `Empire' and `Redchief Delicious' apple trees (Malus domestics Borkh.) was established in 1978 to evaluate four planting systems: 1) slender spindle/M.9, 2) Y-trellis/M.26, 3) central leader/M.9/MM.111, and 4) central leader/M.7a. During the first 5 years, yields per hectare for `Empire' were positively correlated with tree density. In the second 5 years, the Y-trellis/M.26 trees produced the highest yields while yields of the other systems continued to be related to tree density. Cumulative yields were highest with the Y-trellis/M.26 trees. With `Delicious', the Y-trellis/M.26 yields were greatest during all 10 years despite lower tree density than the slender spindle/M.9. Yields of `Delicious' with the other three systems were a function of tree density during the 10 years. At maturity, canopy volume per tree was greatest on the central leader/M.7a trees and smallest on the slender spindle/M.9 trees; however, there were no significant differences in canopy volume per hectare between the systems despite large differences in yield. Trunk cross sectional area (TCA) per hectare was greatest with the Y-trellis/M.26 trees and smallest with the central leader/M.7 trees. Yield was highly correlated to TCA/ha. Yield efficiency with `Empire' was greatest for the slender spindle/M.9 system, followed by the Y-trellis/M.26, central leader/M.9/MM.111, respectively. With both cultivars, the central leader/M.7a system had the lowest yield efficiency. With `Delicious', there were no differences in yield efficiency for the other three systems. The greater yield of the Y-trellis/M.26 system was the result of greater TCA/ha and not greater efficiency. `Empire' fruit size was largest on the central leader/M.7a and the central leader/M.9/MM.111 trees and smallest on the slender spindle/M.9 and the Y-trellis/M.26 trees. With `Delicious', fruit size was larger with the Y-trellis/M.26 trees than the other systems. When fruit size was adjusted for crop density, there were no significant differences due to system with `Empire', but with `Delicious' the Y-trellis/M.26 trees had larger adjusted fruit size than the other systems. Crop density calculated using TCA correlated better to fruit size than did crop density calculated using annual increase in TCA, canopy volume, or land area. Fruit color and quality with `Redchief Delicious' were not influenced by system. With `Empire', average fruit color and soluble solids content were lower for the Y-trellis/M.26 and slender spindle/M.9 in some years when canopy density was allowed to become. excessive.

Experiments were conducted at Adjuntas substation in the central mountain region of Puerto Rico to determine the effect of four rootstocks on growth and fruit production parameters of six clones of Valencia orange. Concerning fruit characteristics, the most notable differences among clones were in size, but also statistical differences were found in peel percentage and number of seeds per fruit. Significant differences in juice characteristics among clones were also found. Fruit production was superior for all four clones with Cleopatra mandarin as rootstock.There was significant difference between clones 3164 and 3264 concerning fruit production. There were no significant differences in yield efficiency during the first crop year; however, trees on Cleopatra mandarin and sour orange rootstocks were significantly taller, wider and had larger canopy volumes. Significant differences among different clones within particular rootstocks were found for tree height, tree width, canopy volume, fruit production and yield efficiency.

Dwarfing Rootstocks

As in several fruit crops, citrus trees with decreased size allow for a higher planting density, which may lead to higher productivity and facilitate operations such as harvesting and spraying. The use of dwarfing rootstocks is one of the most feasible methods for tree size control, but few commercial varieties are available to date. In this work, the long-term performance of Valencia sweet orange grafted onto 51 hybrid citrus rootstocks was evaluated in rainfed cultivation at 6.0 m × 2.5 m tree spacing in Northern São Paulo State, Brazil. About a third of the evaluated hybrids were classified as dwarfing and semi-dwarfing rootstocks, that is, respectively inducing a relative canopy volume of <40% and 40–60% compared withthe standard rootstock, the Rangpur limeSanta Cruz selection. The production efficiency and soluble solids concentration were conversely related to the canopy volume. Three citrandarins of Sunki mandarin (TSKC) × Flying Dragon trifoliate orange (TRFD) were grouped within the most productive dwarfing rootstocks. Other hybrids that expressively decreased tree size were mainly sensitive to drought; therefore, the mean fruit yield was low, indicating the need for irrigation, albeit fruit quality was high. Estimated productivity on the selected TSKC × TRFD rootstocks would double to an average of 40 t·ha−1·year−1 if tree spacing wasadjusted to the smaller tree size. Although the HTR-208 citrandarin and the LCR × CTSW-009 citrumelimonia were as vigorous as the Santa Cruz Rangpur lime, they induced an outstanding fruit yield due to their highertolerance to drought and, hence, can be considered for rainfed cultivation at wider tree spacing.

Abstract Carbon allocation between source and sink organs determines plant growth and is influenced by environmental conditions. Under water deficit, plant growth is inhibited before photosynthesis and shoot growth tends to be more sensitive than root growth. However, the modulation of source-sink relationship by rootstocks remain unsolved in citrus trees under water deficit. Citrus plants grafted on Rangpur lime are drought tolerant, which may be related to a fine coordination of the source-sink relationship for maintaining root growth. Here, we followed 13C allocation and evaluated physiological responses and growth of Valencia orange trees grafted on three citrus rootstocks (Rangpur lime, Swingle citrumelo and Sunki mandarin) under water deficit. As compared to plants on Swingle and Sunki rootstocks, ones grafted on Rangpur lime showed higher stomatal sensitivity to the initial variation of water availability and less accumulation of non-structural carbohydrates in roots under water deficit. High 13C allocation found in Rangpur lime roots indicates this rootstock has high sink demand associated with high root growth under water deficit. Our data suggest that Rangpur lime rootstock used photoassimilates as sources of energy and carbon skeletons for growing under drought, which is likely related to increases in root respiration. Taken together, our data revealed that carbon supply by leaves and delivery to roots are critical for maintaining root growth and improving drought tolerance, with citrus rootstocks showing differential sink strength under water deficit.
