A Quick Reference Chart was created to provide practical and objective identification of the best rootstock alternatives for ‘Valencia’ orange trees in terms of tree development and industrial properties of juices.Īs 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.
Although the ‘Rangpur’ lime and the ‘Florida’ rough lemon allowed high yields, the trees are very vigorous, with low-quality fruits.
Trees grown on ‘US–812’ citrandarin rootstock had low vigor, good productive performance, accumulated production and production efficiency similar to ‘Rangpur’ lime, and high industrial properties of juices. The F.80–3 and F.80–5 citrumelos also had good dwarfing potential and high production efficiency, but lower industrial properties of juice compared to the other ‘Trifoliata’ hybrid rootstocks. Trees grown on IPEACS–239 and IPEACS–256 citrandarins, and on ‘US–802’ pummelo hybrid had low vigor, high production efficiency and high industrial properties of orange juice, and are therefore potential alternatives for high-density plantings. A randomized block design with four replicates was used. The experimental orchard was planted in Rancho Alegre, PR, Brazil, under clay soil and subtropical rainfed conditions. Twenty rootstock genotypes were evaluated by measuring tree growth and industrial properties of orange juices, including ‘Trifoliata’ hybrids with tangerine (citrandarins) and grapefruit (citrumelos), as well ‘Rangpur’ lime and other potential rootstocks. Therefore, the aim of this study was to assess the impact of rootstock genotypes on tree development and industrial properties of ‘Valencia’ sweet orange juice (Citrus sinensis). The low diversification of rootstock genotypes in orchards limits the expansion of the citrus industry, restricting increases in productivity and cost-saving via phytosanitary treatments and other horticultural practices. Modification of the photosynthetic rate or availability of nutrient minerals. Such as the rootstock/scion interaction, the water uptake capacity of roots, the The influence that the external aspects surrounding plants has on fruit quality, The literature that focuses on physico-chemical parameters, nutritional compoundsĪnd physiological disorders has been revised. To better understand how rootstock influences citrus fruit quality,
Relevant as consumers demand high internal and external qualities to eat citrusįruit fresh. Hence, the quality of citrus fruit is becoming increasingly more Although the emphasis of most studies on rootstocks hasīeen placed on the yield and optimization of the citrus fruit grown in differentĮnvironments, other studies have paid attention to the effect of rootstock onįruit quality. Citrus rootstocks are a relevant tree part that contributes to crops adapting toīiotic and abiotic conditions, it becoming a key factor to face the current era ofĬlimate change.
