The effect of six commercial citrus rootstocks on the growth and yield of Valencia orange, Marsh seedless grapefruit, and Ortanique trees was studied in a rootstock experiment initiated in Jamaica in 1965. Results of these investigations revealed that under the soil and environmental conditions of this experiment, rough lemon and Rangpur lime rootstocks were the most vigorous of the six stocks studied; Cleopatra mandarin was the next most vigorous, while the trifoliate orange was decidedly the least vigorous of the stocks. The widely used sour orange stock was a relatively slow growing stock, and its vigour was about equal to the Troyer citrange rootstock. Yield data taken over the 3-year period 1969 to 1972 showed that the sour orange rootstock produced yields of Valencia orange, Marsh seedless grapefruit, and Ortaniques as good as the more vigorous rough lemon and Rangpur lime rootstocks, and better than the other three stocks, viz., Cleopatra mandarin, Troyer citrange, and trifoliate orange.

This study was conducted during 2002 and 2003 seasons to select the best citrus rootstocks for young `Valencia' orange trees grown under soil salinity stress. Six citrus rootstocks namely Volkamer lemon, Cleopatra mandarin, Troyer citrange, Rough lemon, Egyptian lime, and Sour orange were tested. Four soil salinity levels, namely, 0.0%, 0.1%, 0.2%, and 0.4% were examined. Results showed that growth criteria, plant pigments and percentages of N, P, and K in the leaves of `Valencia' orange onto all citrus rootstocks tended to reduce with raising soil salinity. The harmful effects imposed by soil salinity was `Valencia' orange on Volkamer lemon, Cleopatra mandarin Troyer citrange, Rough lemon, Egyptian lime, and Sour orange, in asending order. Results proved the superiority of Volkamer lemon, Cleopatra mandarin, and Trouyer citrange rootstocks for `Valencia' orange transplants grown under salinity conditions as compared to the other rootstocks. `Valencia' orange on such promising rootstocks could tolerate soil salinity until 0.20% without adverse effects on growth of transplants. Sour orange rootstock seems to be the lowest suitable stock for `Valencia' orange tansplants grown under soil salinity conditions.

Abstract. This investigation was conducted during 2014, 2015 and 2016 in the field of the citrus experimental station in Ciano, the general corps of scientific agricultural researches. The growth and yield of orange trees (Washington navel 141) budded on seven citrus rootstocks (Sour orange, Troyer citrange, Carrizo citrange, Citrumelo 4475, Citrumelo 1452, Macrophylla and Cleopatra mandarin) and farmed since 1989 have been studied. The results for the average of yield showed that the trees grafted on Cleopatra mandarin (58.33 kg. tree-1) were significantly superior to those grafted on Macrophylla (34.17 kg. tree-1). Orange trees grafted on Citrumelo 4475 and Citrumelo 1452 were significantly superior to other treatments in trunk section area of the rootstock (922.41 and 841.02 cm2, respectively). The greatest fruit fresh weight was in trees grafted on Citrumelo 4475 (284.85 g. fruit-1) which were significantly superior to those grafted on Carrizo and Troyer citrange (232.49 and 236.06 g. fruit-1, respectively). The biggest total soluble solids (%) was in trees grafted on Carrizo and Troyer citrange (12.83% for both treatments) which were significantly superior to those grafted on Sour orangе and Macrophylla (11.5% for both treatments), while the greatest total acids (%) was by Sour orange (2.08%) without significant differences.

In an experiment planted in 1971 at the Horticultural Research Station, Somersby, N.S.W., nucellar lemons (Lambert and Taylor Eureka, Villafranca and Prior Lisbon) and 1 old-line cultivar carrying exocortis (Monroe Lisbon) were compared on 5 rootstocks (Troyer citrange, Narara Rough lemon, Rangpur lime, Smooth Seville and trifoliate orange). In the second experiment, planted in 1973, 2 nucellar lemon scions (Taylor Eureka and Prior Lisbon) were compared on 16 rootstocks (4 Rough lemons, 4 Smooth and 1 Rough Seville, New Guinea citron, citremon 1449, Poorman orange, 3 citranges and trifoliate orange). Eureka lemon selections on Troyer citrange and trifoliate orange rootstocks exhibited symptoms of yellow ring incompatibility. Eureka lemon, however, was compatible with Benton citrange; cumulative yield and cropping efficiency were high and tree canopies dense and compact. Trees on Narara and Watkins selections of Rough lemon had high cumulative yields but their size and vigour made harvest difficult. One of the red Rough lemon selections (57-228-502) produced a high yielding and more manageable compact tree with a large proportion of summer crop fruit. Prior Lisbon lemon on trifoliate orange was a medium-sized, compact tree with high cropping efficiency and good juice quality. Villafranca performed well on all rootstocks except Smooth Seville. The results are discussed with respect to planting densities, proportion of summer and main crop fruit and juice yield and quality.

Just because of geographical spread, citrus species generally grow in places sensitive to salinity. Testing methods have a significant role in breeding and cultivar development programs. This study was conducted to investigate in vitro salt response of Cleopatra mandarin (Citrus reshni Tan.), sour orange (Citrus aurantium L.), rough lemon (Citrus jambhiri Lush.), Volkamer lemon (Citrus volkameriana Tan & Pasq.), Carrizo citrange (Poncirus trifoliata L. Raf. X Citrus sinensis L. Osbeck) and trifoliate orange (Poncirus trifoliata Raf.) rootstocks at different NaCl concentrations. Seeds were germinated in MS medium with 0, 45, 90 and 135 mM NaCl concentrations. In general, the greatest germination rates in all salt concentrations in Volkamer lemon and sour orange rootstocks and the lowest values were observed in rough lemon and trifoliate orange rootstocks. Present findings revealed that in vitro conditions could reliably be used in salt tolerance tests of citrus rootstocks.

Mal Secco

SUMMARYCitrus trees are often exposed to severe infectious diseases. Mal secco caused by Phoma tracheiphila (Petri) Kantschaveli and Gikashvili is one of the most destructive fungal diseases of lemons (Citrus limon Burm. F.). In the present study, antioxidant enzyme activity in different mal secco-resistant and susceptible citrus rootstocks including Cleopatra mandarin (C. reshni Tan.), sour orange (C. aurantium L.), rough lemon (C. jambhiri Lush.), Volkameriana (C. volkameriana Tan. and Pasq.), Carrizo citrange (Poncirus trifoliata L. Raf. X C. sinensis L. Osbeck) and trifoliate orange (P. trifoliata) was investigated. Possible differences in constitutive levels of these antioxidant enzymes and correlations between enzyme levels and mal secco caused by P. tracheiphila were examined. Among the rootstocks, Cleopatra mandarin was found to be resistant to mal secco, whereas rough lemon, sour orange and trifoliate orange were highly susceptible. Total peroxidase (TPX; EC: 1.11.1.7) activity increased in all infected rootstocks. Ascorbate peroxidase (APX; EC: 1.11.1.11) activity increased in most of the rootstocks and no correlation was found between catalase (CAT; EC: 1.11.1.6) activity and mal secco resistance. This study indicates that overall TPX activity is upregulated and APX activity is up- and down-regulated depending on the type of rootstock in response to P. tracheiphila infection.

The 'Tahiti' lime (Citrus latifolia Tanaka) is an important commercial citrus cultivar in Brazil. 'Rangpur' lime has being used as its main rootstock, but it is susceptible to root rot caused by Phytophthora, reducing tree longevity. An experiment was set up in a randomized block design, with three trees per plot of each rootstock and four replicates, and run for 12 years, aiming to compare the performance of 'IAC-5 Tahiti' lime, budded on 'Rangpur' lime (Citrus limonia Osb.); 'C-13' citrange (Citrus sinensis (L.) Osb. × Poncirus trifoliata (L.) Raf.); 'African' rough lemon (Citrus jambhiri Lush.); 'Volkamer' lemon (Citrus volkameriana Ten. & Pasq.); trifoliate orange (Poncirus trifoliata (L.) Raf.); 'Sunki' mandarin (Citrus sunki Hort. ex Tan.) and 'Cleopatra' mandarin (Citrus reshni Hort. ex Tan.). Eleven years after the establishment of the orchard, trees with the greatest canopy development were budded on 'C-13' citrange and 'African' rough lemon, and both differed significantly from trees budded on trifoliate orange, 'Sunki' and 'Cleopatra' mandarins, which presented the smallest canopy development. Trees budded on 'Rangpur' lime and 'C-13' citrange had the highest cumulative yields, and were different from trees budded on trifoliate orange, 'Cleopatra' and 'Sunki' mandarins. There was no rootstock effect on mean fruit weight and on the total soluble solid/acid ratio in the juice. The 'Rangpur' lime and the 'Cleopatra' mandarin rootstocks reduced longevity of plants.

Five scions and ten rootstocks were tested in an eight-year trial at Irymple, near Mildura, Victoria. The scions were two old-line Lisbons, a nucellar Eureka, and two old-line Eurekas. Cumulative yields averaged for the ten rootstocks and expressed as a percentage of the best scion were : Rix Lisbon 100, Doncaster Lisbon 99, Frost Nucellar Eureka 95, Rodwell Eureka 89, and Villa Franca Eureka 73. The rootstocks, with their percentage yields in parentheses, were : Rough lemon (100), Cavanagh sweet orange (90), Symons sweet orange (84), Marsh grapefruit (73, Cox sweet orange (74), Cleopatra mandarin (72). Seville sour orange (721, Sampson tangelo (69), Emperor mandarin (69), and Carrizo citrange (30). The poor performance of Carrizo citrange is discussed in terms of virus infection and incompatibility. The incidence and importance of scion overgrowth is also reported and discussed.

Grafted plants of Valencia orange scion [Citrus sinensis (L.) Osbeck] on six different rootstocks were grown under glasshouse conditions and supplied with dilute nutrient solution containing either 0 or 75 mM NaCl. Salt treatment was increased to 150 mM NaCl after 49 days. Leaf water relations and leaf chloride, sodium and potassium concentrations were followed throughout the period of salt treatment until day 105, when salt treatment ceased, and thereafter until day 140. Seedlings of Rangpur lime (C. reticulata var. austera hybrid?), Cleopatra mandarin (C. reticulata) and sweet orange (C.sinensis) were treated similarly and leaf water relations and chloride concentrations were followed until salt treatment ceased on day 77. All Valencia-rootstock combinations adjusted osmotically to the salt stress imposed and maintained turgor pressures at or above control values. Mature leaves on seedlings of sweet orange behaved similarly to Valencia orange leaves on sweet orange rootstocks by maintaining turgor pressures higher than control values. In contrast, mature leaves on seedlings of the genotypes Rangpur lime and Cleopatra mandarin tended to lose turgor during the period of treatment with 150 mM NaCl. Leaf chloride analyses indicated that Rangpur lime and Cleopatra mandarin rootstocks restricted the uptake and/or transport of chloride to shoots. However, comparatively high concentrations of sodium (>approx. 200 mM, tissue water basis) were accumulated in mature leaves on all rootstocks during salt treatment. Leaf potassium concentrations remained similar to control values. The reduction in osmotic potential in mature Valencia leaves on rough lemon (C. jambhiri), Trifoliata (Poncirus trifoliata), Camzo citrange (C. sinensis × P. trifoliata) and sweet orange rootstocks on day 77 could be accounted for largely by the increase in sodium and chloride, whereas chloride (as NaCl) accounted for only approximately 50% of the reduction in osmotic potential in Valencia leaves on Rangpur lime and Cleopatra mandarin rootstocks. Stomatal resistances in mature Valencia leaves on all rootstocks were increased by salt treatment and showed only partial recovery after the cessation of salt treatment. The incomplete recovery may have been associated with the retention in leaves of high concentrations of sodium.

In 1968, the CRA-Research Center for Citriculture and Mediterranean Crops (CRA-ACM) started a research program aimed at breeding citrus rootstocks. The monoembryonic species C. latipes (Swing.) Tan. was used as the female parent; trifoliate orange [Poncirus trifoliata (L.) Raf.], sour orange, and volkamer lemon (C. volkameriana Pasq.) were used as male parents. The behavior of some of these hybrids tested with other standard rootstocks in Sicily and Sardinia was evaluated. The cultivars under comparison included ‘Washington’ navel orange and ‘SRA 92’ clementine in Sardinia and ‘Tarocco’ orange in Sicily. Our results showed the dramatic influence of rootstock on plant growth and yield; only minor effects on fruit quality were observed. Among the standard rootstocks tested, Swingle citrumelo provided the highest yield. Some of the tested hybrids (F5 P12, F6 P12, and F6 P13) may improve plant yield, thus maintaining good fruit quality. Encouraging data obtained with these hybrids may justify the use of monoembryonic species of the Papeda subgenus for breeding citrus rootstocks.
