“…The reason might also be the better stock-scion compatibility used in the study. Similar results had been stated by Girardi and Filho (2006) who worked on different sweet orange varieties and found significant effect on root growth and volume of the plants. The data about different times of budding also showed significant influence on root volume.…”

In sexual propagation of citrus long juvenility, genetic impurity and self incompatibility are the major problems. Hence the use of suitable rootstock is a pre-requisite in citrus propagation. Now a days, the cultivation of sweet orange is boosting up among citrus cultivation. Due to this, there is a great need for the evaluation of sweet orange cultivars onto an appropriate rootstock. A research trial was carried out in consideration with ‘Blood Red’, ‘Jaffa’ and ‘Valencia Late’ sweet orange cultivars T-budded on Carrizo rootstock at five different intervals of first week of July, August, September, October and February. The treatments were replicated thrice and statistically arranged in factorial randomized complete block design. As a result of the study significant variations were noticed in the performance of cultivars under study at various budding intervals. Out of the sweet orange cultivars ‘Blood Red’ was the first to initiate sprouting in 28.30 days with healing of bud union in 31.39 days, maximum survival (89.40%), plant height (22.93 cm), number of branches buddling-1 (1.14), leaf total nitrogen (1.89%), phosphorus (0.07%) and potassium (1.26%). Among budding intervals, the plants budded on the first week of September were the first to sprout in 26.46 days achieving maximum (23.04 cm) plant height, branches buddling-1 (1.15) root formation of (5.98 cm3) volume and survival percentage (91.99). Commercially, ‘Blood Red’ sweet orange cultivar budded in the first week of September can be cultivated for superior progeny.

“…The graft incompatibility is considered a physiological disorder between the scion and the rootstock tissues that result in an inadequate, incomplete or absent graft union and further poor plant development (Pompeu Junior 2005). 'Pera' sweet orange is well-known as incompatible with trifoliate orange rootstock (P. trifoliata) and many of its hybrids like 'Swingle' citrumelo (Pompeu Junior 2005), in addition to the 'Volkamer' and 'Rough' limes rootstocks (Donadio 1999;Girardi and Mourão Filho 2006). Pompeu Junior and Blumer (2014) observed the occurrence of incompatibility between two selections of 'Rangpur' lime × 'Carrizo' citrange (C. ×sinensis × P. trifoliata) and a 'Cleopatra' mandarin × 'Swingle' trifoliate citrandarin with 'Pera IAC'; on the other hand, Schinor et al (2013) reported that some trifoliate hybrids rootstocks may be graft-compatible with this scion variety.…”

The search for alternative rootstocks to the 'Rangpur' lime tree is a challenge to the sustainability of citrus in the Tabuleiros Costeiros (Coastal Tablelands) of Northeastern Brazil. New varieties should meet high drought tolerance with water deficit, cohesive soils, resistance to citrus diseases and inducing high production of fruit. In this work, the performance of 'Pera' sweet orange was evaluated on 'Tropical Sunki' mandarin and 27 hybrid citrus rootstocks in Umbaúba, Sergipe. A local selection of the 'Rangpur' lime was the control. Planting was in 2013 at tree spacing of 6.0 × 3.0 m, without irrigation. Tree size, fruit yield and quality, tree survival rate and graft-compatibility were assessed until 2019. Experimental design was completely randomized blocks with 29 treatments, three replicates and four plants in the plot.Two selection indices were applied to the data to assist in decision making. The 'Tropical Sunki' mandarin induced similar cumulative fruit yield in relation to the 'Rangpur' lime, suggesting a good drought tolerance of the former rootstock. The TSKC × (LCR × TR) -073 induced slightly lower productivity, compensated by higher productive efficiency and higher concentration of soluble solids, whereas LCR × TR -001 and HTR -166 were highly efficient dwarfing rootstocks. The multiplicative and the rank sum indices showed high correlation, both classifying 'Tropical Sunki' mandarin, 'Santa Cruz Rangpur' lime, LVK × LCR -010 and -038, HTR -127, in addition to the three aforementioned hybrids, as superior to the local selection of 'Rangpur' lime.

“…and some of its hybrids, such as the 'Swingle' citrumelo . When needed, the production of 'Pera' trees is possible by using inter-grafting, the attachment of a 'filter' or 'sandwich' of another sweet orange graft, for example a graft of 'Valencia' between the 'Pera' and 'Swingle' (GIRARDI; MOURÃO FILHO, 2006;CARVALHO et al, 2011). Although the cost of producing inter-grafted trees is higher than that of conventional trees, this technique has made it possible to produce 'Pera' in regions with a high risk of CSD, such as in the northern part of São Paulo state and in the southern part of Triangulo Mineiro in Minas Gerais state (JESUS JUNIOR; BASSANEZI, 2004), where the use of 'Rangpur' lime (C. limonia Osbeck) as a rootstock is not recommended.…”

Citriculture is an important agricultural activity worldwide, occupying a relevant position in Brazil among fruit tree production for both the fresh fruit market and the processing industry for concentrated orange juice export. Recent advances in the country’s citrus nursery tree production system have been essential to guarantee the efficiency and competitiveness of Brazilian citriculture. The implementation of strict laws and regulations to produce trees in protected environments and improvements in production techniques for basic citrus propagation materials and nursery trees in São Paulo state has excluded the insect vectors of destructive diseases such as citrus variegated chlorosis and huanglongbing, making this an innovative reference system for citrus propagation around the globe. The main aspects of these advances are presented and discussed in this review, including advances in propagation techniques, scion and rootstock selection, genetic characterization and certification, tree size standards, cultural practices such as irrigation and fertilization for the production of citrus propagation materials and nursery trees, and nursery management tools.
