“…Despite it being well-documented that grafting can affect fruit organoleptic and nutritive qualities such as the content of bioactive compounds [58][59][60][61][62], it is still unclear how rootstocks exert their influence on these characteristics. The results discussed here suggest that the performances of grafted trees are related to more specific interactions between scion and rootstock and not simply to factors such as plant water and nutrient status or crop yield [3].…”

Rootstock choice has important effects on the horticultural and pathological traits of the citrus cultivars. Thus, the scion/rootstock combination can affect tree vigour, nutrition, and stress resistance; it can also have positive influences on the fruit quality traits. Although the study of rootstock effects has been a relevant research topic in citrus for many years, the main body of such study has been conducted at the biochemical level, while little effort has been directed to the determination of the rootstock influences at the molecular level. A comparative study of three combinations of scion and rootstock shows a positive correlation between the regulation of the fruit quality-related genes and the accumulations of bioactive compounds, as well as with acid degradation. Monitoring the anthocyanin accumulation during ripening shows the scion/rootstock combination can increase anthocyanin synthesis in the fruit, as well as vitamin C accumulation and acid degradation. Our results show that the rootstock genotype can exert important influences on citrus fruit quality by affecting gene expression in the scion. New insights into the molecular interactions between scion and rootstock may help unravel the systems through which rootstocks exert their influences on the regulatory networks in the scion, so as to influence relevant agronomic traits. This information should result in an improved rootstock breeding selection and definition of scion/rootstock combinations to enhance fruit quality traits.

“…Sweet orange grafted onto different rootstock presented variability on turgor, osmotic potential, osmotic adjustment and bulk modulus of elasticity in leaves (Gonçalves et al, 2016). Grapefruit cv 'Marsh Seedless' and 'Redblush' grafted on nine rootstocks presented variation gas exchange parameters, relative water content and enzyme content (Sharma et al, 2015). Moreover, Santos et al (2019) also reported that 'Rangpur Santa Cruz' lime and 'Sunki Maravilha' mandarin grafted on different rootstock presented variation in tree physiology, enzyme activity and chlorophyll contents.…”

Background: RGL mandarin is one of the important mandarin citrus varieties in Indonesia. The tolerance of RGL mandarin citrus to water deficit can be induced by the rootstock. This study aimed to characterize the physiological responses and transcriptional gene expression of RGL mandarin citrus grafted onto three rootstock genotypes during the dry and the rainy seasons.Methods: Three-years-old mandarin citrus trees cv. Rimau Gerga Lebong (RGL) grafted onto three citruses (JC, Cit and K) were planted at the experimental field of the ICISFRI. The experiment was conducted with a randomized block design and each scion-rootstock combination contained five replications. All of the physiological and relative gene expression parameters observed were conducted at the last of the dry season (September 2019) and the mid of the rainy season (January 2020). Water deficit was induced by no watering plants during the dry season.Result: The results of physiological responses and relative gene expression analyses showed that RGL-Cit combination had better than RGL-JC combination and RGL-JC combination had better than RGL-K combination. RGL-Cit combination showed less wilt than RGL-JC and RGL-K combinations. The RGL-Cit combination had the highest stomatal density, stomatal aperture, stomatal conductance and photosynthetic rate in the dry season. Different plant combinations showed different gene expressions. RGL-JC and RGL-K combinations were upregulated in almost all the primers related to drought responses tested in the dry season. RGL-Cit combination only upregulated the PIP1, PIP2 and ACS2 and unregulated the others in the dry season. Therefore, citrumelo seems to be a valuable type of rootstock.

The use of rootstocks provides choices to growers to increase fruit quality and yield, obtain high-density planting, avoid juvenility, and control tree size. The choice of rootstock for a citrus orchard was an important consideration. The aim of the study was to evaluate the effects of citrus rootstocks on leaf mineral composition and leaf physiology of the citrus commercial cultivars (‘Pontianak’ tangerine, ‘Pamindo’ pamelo and ‘Montaji’ lemon). For this purpose, the citrus commercial cultivars were budded onto Japansche citroen (JC) and Citrumelo rootstocks and then leaf mineral composition (total nitrogen, phosphor and kalium concentration) and leaf physiology (chlorophyll index, respiration rate, stomatal conductance and photosynthetic rate) of each scion were measured. Results showed that rootstock type had different influence on leaf mineral composition and leaf physiology in leaf of each scion. For total nitrogen, total kalium and stomatal conductance variables, rootstocks had no effect. For total phosphor variable, JC rootstock induced higher value than Citrumelo in all scion. For chlorophyll Index variable, Citrumelo induced higher value on ‘Pamindo’ and lower value on ‘Montaji’ than JC but had no effect on ‘Pontianak’ tangerine. For respiration rate and photosynthetic rate variable, Citrumelo induced higher value than JC in ‘Pamindo’ but had no effect on ‘Pontianak’ tangerine and ‘Montaji’. Therefore, ‘Pamindo’ was better to be budded on Citrumelo, ‘Montaji’ and ‘Pontianak’ tangerine were better to be budded on JC.
