ex vitro mycorrhization of vitro derived plantlets of carrizo Citrange c sinensis l osb p trifoliata l raf
Acta Horticulturae, 2015Co-Authors: Benedetta Chiancone, F G Casales, Vincenzo Mondello, Livio Torta, Santa Burruano, Maria GermanaAbstract:In this study, vitro-derived plantlets of âCarrizoâ Citrange were inoculated with Glomus intraradices during the acclimatization phase, from in vitro to in vivo. Plantlets were grown in presence (+M) and in absence of inoculum (-M) and in addition, in sterile and non-sterile substrate. After three months of culture, some vegetative parameters and the level of infection, varied greatly in the different theses. In particular, the highest formation of new branched roots has been observed in inoculated plantlets cultivated in sterile substrate. Good results were observed also in non-inoculated plantlets cultivated in non-sterile substrate, in presence of endemic inoculum. The same trend was observed analyzing the mycorrhizal infection. In fact the highest level of mycorrhization was observed both in inoculated plantlets in sterile substrate and non-inoculated plantlets in non-sterile thesis. Although the symbiosis induced a better growth of the rooting apparatus, results confirmed the low mycorrhizal-dependence of Citrange, also regarding in vitro-derived plantlets.

biotization of encapsulated in vitro derived propagules of carrizo Citrange
Acta Horticulturae, 2015Co-Authors: Maria Germana, Micheli Maurizio, B Chiancone, Carmen Bianco, Fabrizio Giuseppe Casales, Roberto DefezAbstract:The encapsulation technology represents a new tool to integrate micropropagation into the nursery activity. It allows combining the advantages of zygotic or gamic seeds with those of micropropagation. The synthetic or artificial seeds have been defined as âartificially encapsulated somatic embryos, shoots or other tissues which can be used for sowing under in vitro or ex vitro conditionsâ. This will be a powerful propagation tool in the nurseryman hands, if the levels of the synthetic seeds conversion can be increased also in the nurseries, without the asepsis of in vitro laboratories and with the presence of many parasitic microorganisms, like bacteria and fungi, responsible for contamination and/or for trophic competition. This research was carried out in order to apply biotization into the synthetic seed technology of Carrizo Citrange [C. sinensis (L.) Osb. A Poncirus trifoliate (L.) Raf.], one most extensively used citrus rootstock, because of its resistance to the Citrus tristeza virus (CTV). With this goal, preliminary experiments to set up protocols for biotization, through the introduction of Plant Growth Promoting Bacteria (PGPB) into calcium alginate capsules of Carrizo Citrange in vitro-derived microcuttings, were carried out, in order to protect the plantlets from abiotic and biotic factors and to promote their growth during the first stages of development. Specifically, the Sinorhizobium meliloti wild type strain 1021 and its derivative RD64, that synthesizes 80-fold more IAA as compared to the wild type strain, was used to evaluate their performance in inducing rooting of encapsulated microcuttings.

organogenesis and encapsulation of in vitro derived propagules of carrizo Citrange citrus sinensis l osb poncirius trifoliata l raf
Plant Cell Tissue and Organ Culture, 2011Co-Authors: Maria Germana, Benedetta Chiancone, Maurizio Micheli, L Macaluso, Alvaro StandardiAbstract:Due to widespread polyembryony, Citrus rootstocks are usually propagated by open-pollinated seed germination, although micropropagation offers many advantages. Encapsulation technology has recently attracted the interest of researchers in the field of plant propagation because it combines the advantages of zygotic or gamic seeds with those of micropropagation. In this study, we examined the encapsulation of Carrizo Citrange uninodal microcuttings (3–4 mm long) and evaluated the influence of the calcium alginate coating, a short time storage at cold temperature, and different sowing substrates on the viability and regrowth of the explants. A secondary aim was to develop an efficient protocol to induce root formation in the microcuttings. The results showed that encapsulation did not negatively affect the viability, providing a satisfactory regrowth, and storage potential for 30 days at low temperature. No differences in viability and regrowth were detected between the two different sowing substrates tested (agar-solidified medium and paper filter). To optimize the production of microcuttings required to perform the encapsulation experiments, in a preliminary experiment we assessed different factors affecting the in vitro shoot regeneration from epicotyl segments (obtained from seeds of Carrizo Citrange germinated in vitro), including the influence of in vitro organogenesis, explant orientation, cut surface contact with the medium, treatments with different growth regulators, and distance of the organogenic explants from the cotyledonary node. The highest organogenic response was obtained from segments horizontally cultured (particularly from the basal portion), from segments with the cut surface in contact with the medium and from explants cultured on medium supplemented with 6-benzyladenine. No significant difference in regeneration efficiency was found in response to the distance of the epicotyl portions from the cotyledonary node.

Growth, yield, and fruit quality of Rhode red Valencia and Valencia Late sweet oranges grown on three rootstocks in eastern Mediterranean
Chilean journal of agricultural research, 2020Co-Authors: Ercan Yildiz, Turan Hakan Demirkeser, Mustafa KaplankiranAbstract:The plant growth, yield, yield efficiency, and fruit quality of 'Rhode Red Valencia' and 'Valencia Late' sweet oranges (Citrus sinensis (L.) Osbeck) on three rootstocks were evaluated under Eastern Mediterranean climatic conditions of Dortyol-Hatay, which is one of the oldest and largest citrus and mandarin (Citrus reticulata Blanco) production regions in Turkey. The fruit yield was affected by rootstock in both scion cultivars from 2007 through 2010. Trees on 'Troyer' Citrange had lower yield than those budded on the other rootstocks. The yield of 'Rhode Red Valencia' and 'Valencia Late' orange trees on 'Carrizo' Citrange were about 9% and 19% more than those on 'Troyer' Citrange, respectively. But trees on 'Troyer' Citrange had significant higher yield efficiency than trees on sour orange and 'Carrizo' Citrange, because of canopy volume of 'Troyer' Citrange was lower than the other rootstocks. The heaviest fruits of 'Valencia Late' orange trees were harvested from 'Carrizo' Citrange (214.69 g), while 'Rhode Red Valencia' orange trees did not show differences regarding the rootstock. The rootstocks had no significant effects on juice content of 'Rhode Red Valencia' and 'Valencia Late' oranges. The effects of the rootstocks in both scion cultivars on juice content, total acids (TA), Brix:TA ratio, and number of seeds per fruit were found to be insignificant

Effects of rootstocks on storage performance of Nova mandarins
Turkish Journal of Agriculture and Forestry, 2019Co-Authors: Ahmet Erhan Özdemir, Mustafa Kaplankiran, Öznur Didin, Elif Candir, Ercan YildizAbstract:In this research, the effects of rootstocks on the storage performance of Nova mandarins grafted on Carrizo Citrange, Troyer Citrange, or sour orange grown in the ecological conditions of Dortyol were studied. Fruits were harvested at optimum maturity and kept at 4 °C and 6 °C for 120 days. Changes in weight loss, incidence of fungal decay and physiological disorders, juice content, total soluble solids (TSS), percent fruit with green button, titratable acidity (TA), juice pH, vitamin C content, and rind color (L*, C*, h°) were monitored at 15-day intervals during storage to determine the effects of rootstock on postharvest quality of Nova mandarins. The fruit of Nova mandarin grafted on sour orange and Carrizo Citrange had higher weight loss than Troyer Citrange. Weight loss from Nova mandarins kept at 4 °C and 6 °C reached 7.71% and 12.21%, respectively, after 120 days of storage. Juice pH, incidence of fungal decay, and physiological disorders increased, while juice content, TA, vitamin C content, percent fruit with green button, and L*, C*, and h° values of rind color decreased in the Nova mandarin cultivar during cold storage. According to the data, the fruits of Nova mandarin grafted on Carrizo Citrange, Troyer Citrange, or sour orange were stored better at 4 °C than 6 °C. Fruit could be kept at 4 °C for 75 days and at 6 °C for 45 days without any quality deterioration.

EFFECT OF CITRUS ROOTSTOCKS ON LEAF MINERAL COMPOSITION OF ‘OKITSU’, ‘CLAUSELLINA’, AND ‘SILVERHILL’ MANDARIN CULTIVARS
Journal of Plant Nutrition, 2012Co-Authors: C. Toplu, Mustafa Kaplankiran, Veli Uygur, T. Hakan Demirkeser, Ercan YildizAbstract:Citrus performance is strongly related with rootstock. This study was conducted to investigate leaf nutrient contents of ‘Okitsu’, ‘Clausellina’ and ‘Silverhill’ mandarin cultivars budded onto sour orange, ‘Carrizo’ and ‘Troyer’ Citrange rootstocks in Dortyol, Turkey in 2004 and 2005. The maximum nitrogen (N), potassium (K), and copper (Cu) contents were determined for ‘Clausellina’; phosphorus (P) for ‘Okitsu’; and sodium (Na) for ‘Silverhill’. Calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), and zinc (Zn) uptake were similar for the mandarin cultivars. ‘Carrizo’ Citrange at N, K, Mg, Mn, and Cu uptake; ‘Troyer’ Citrange at N, P, K, and Fe uptake; and common sour orange at Ca, Zn, and Na uptake was superior on the other rootstocks. It was observed that ‘Carrizo’ and ‘Troyer’ Citrange rootstocks had advantages over sour orange in nutrient uptake. Thus, growth performance, yield, and quality parameters considered, ‘Carrizo’ and/or ‘Troyer’ Citranges could be suggested as rootstocks for the studied ...

Yield and fruit quality performance of Nova and Robinson mandarins on three rootstocks in Eastern Mediterranean.
African Journal of Agricultural Research, 2009Co-Authors: T. H. Demi̇rkeser, Mustafa Kaplankiran, C. Toplu, Ercan YildizAbstract:Yield and fruit quality performances of Nova and Robinson mandarins were evaluated in the Mediterranean climate of Dortyol, Hatay, Turkey from 2002 to 2007. The cumulative yields of both Nova and Robinson mandarins over this 6 year production period were highest on Carrizo Citrange and smallest on Troyer Citrange. The fruit weight and seed content were affected by the rootstock in Nova mandarin. The heaviest fruits were obtained from Troyer Citrange. For Robinson mandarins, the fruit weight and size were not affected by the rootstock, whereas the fruit color and skin structure were found to be affected by the rootstocks. In the two mandarin cultivars evaluated, the rind thickness, juice content, total soluble solids (TSS), total acidity (TA) and TSS/TA ratio were similar when the rootstocks were compared. For Nova and Robinson mandarins, all of the rootstocks gave good fruit quality for the fresh fruit markets in the Eastern Mediterranean region. In conclusion, we propose Carrizo and Troyer Citranges as an alternative to sour orange rootstocks. Key words: Mandarin, carrizo Citrange, sour orange, troyer Citrange, mediterranean.

distribution and mobility of foliar applied boron 10b in Citrange rootstock under different boron conditions
Journal of Plant Growth Regulation, 2020Co-Authors: Xiuwen Wu, Muhammad Riaz, Cuncang JiangAbstract:Although foliar-applied boron (B) could rapidly and effectively relieve B deficiency of plants, the distribution and mobility of foliar-applied B in Citrange, an important rootstock of citrus, are poorly understood. This study aimed to investigate the transportation and variation of B allocation in different parts of Citrange under different B conditions by spraying 10B on the lower mature leaves of Citrange rootstock for 8 weeks. The results indicated that foliar B on lower mature leaves led to higher 10B abundance and 10B concentration in different parts of plants. Compared with the low-B plants, 10B abundance in stems, lower, and upper mature leaves of medium-B plants increased 23.95, 7.22, and 8.33% respectively. Moreover, under low- and medium-B conditions, abundance and percentage of 10B were higher in roots than that in other tissues after foliar application 10B. Meanwhile, abundance and percentage of foliar-10B in stems and old leaves under B-insufficient condition were much lower than that of B-sufficient condition. Furthermore, the 10B allocation rate was the highest in roots under the two different B conditions. There were higher 10B allocation rates in new leaves and lower mature leaves, and lower 10B allocation rates in stems and upper mature leaves in medium-B plants comparing with that in low-B plants. All these results suggest that foliar-applied 10B on lower mature leaves could be translocated to every part of Citrange rootstock, with the majority distributed in roots, and the mobility of foliar B from lower mature leaves to other parts was different between low- and medium-B treatments, leading to a significant variation in translocation rate for each part of Citrange.

boron distribution and mobility in navel orange grafted on Citrange and trifoliate orange
Plant and Soil, 2012Co-Authors: Ruidong Wang, Lishu Wu, Shuang Peng, Yunhua Wang, Cuncang JiangAbstract:Background and Aims In China, boron (B) deficiency is frequently observed in citrus orchards, and is responsible for considerable loss of productivity and quality. A better understanding of B distribution and remobilization within orange plants is important for developing programs in rational fertilization and effective mitigation of B-deficiency. In the present study (i) the distribution of newly absorbed B and (ii) the translocation of foliar-applied B in ‘Newhall’ navel orange grafted on Citrange and trifoliate orange was investigated.
