Brazil stands out in the production of sweet oranges (Citrus sinensis (L.) Osbeck), citriculture is one of the most important sectors of agribusiness in Brazil. As claimed by the Food and Agriculture Organization (2018), the annual production of these fruits represents about 35% from the whole national production. Rio Grande do Sul (RS) is the sixth largest producer in the country, with 352.451 tons per year (IBGE, 2020). The citriculture uses both the graft and the rootstock, the last one, due to phytosanitary problems, since it has a narrow base, is more susceptible to pests and diseases. (RODRIGUES et al., 2015)<\/p>\n

In order to evaluate the 42 rootstocks behavior during the development of \u201cVal\u00eancia Late<\/em>\u201d orange tree seedlings in the nursery-phase, researchers from the Federal Univeristy of Pelotas (UFPel) in partnership with the Empresa Brasileira de Pesquisa Agropecu\u00e1ria<\/em> and the Instituto Nacional de Investigaci\u00f3n Agropecu\u00e1ria<\/em> (INIA), elaborated the scientific paper Nursery performance of potentially promising rootstocks to Brazil\u2019s south citriculture<\/a>, published in Ci\u00eancia Rural<\/em> (vol. 52, n1).<\/p>\n

In order to reach the results, the study was developed in a completely randomized cohort design, explains researcher L\u00e9o Omar Duart marques. \u201cWe kept track of the development of the rootstock during their nursery phase.\u201d In the end of the study, grafting was performed; it consists of the junction of two different species, using the \u201cVal\u00eancia Late<\/em>\u201d technique, extensively used in the south of Brazil. The results points to possible alternatives of rootstock: \u201cThese alternatives will be tested A CAMPO, since our research focused on studying the initial growth of the rootstock, till its grafting\u201d, highlights Marques.<\/p>\n

The research brings important support to the citriculture in the South area of Brazil. \u201cBy offering new possible alternatives of rootstock, we expand the genetic base of rootstocks and this tends to lower the risk of diseases occurring that in the predominant genotype of the regions citriculture may be susceptible. \u2018As an example, in the appearance of a disease where the trifoliata is susceptible and the \u201crough rind clover lemon tree\u201d genotype presents tolerance or resistance, the grafted plants in this genotype would survive, or vice versa\u201d, explains researcher L\u00e9o Marques.<\/p>\n

The rootstock also influences the other characteristics such as the fruit\u2019s flavor and productivity. \u201cBut, it’s important to consider that in the south region in Brazil, frosts are common to occurred, making it necessary an initial research on their adaptation, to minimize the risks of the citric belt inserting a new genotype of rootstocks, since many genotypes of citrus rootstocks can’t tolerate frosts.\u201d, he completes.<\/p>\n

According to the researcher, the paper opens doors to possible future research: \u201cIn our research we pointed out which rootstocks need special attention in new researches, we believe that we are forming and alicerce to further studies in addition to the previously studied rootstocks, which forth therefore we hope they will be used in large scale by the South’s of Brazil citriculture\u201d, concludes.<\/p>\n
