“…The productive efficiency presented in Table 4 of the best rootstocks was higher compared to sweet orange on different rootstocks (Azevedo, Rosseto, Schinor, Martelli, & Pacheco, 2012;Brugnara & Andrade, 2019;Giampani, Tazima, Baba, Yada, & Leite Júnior, 2016;Rodrigues et al, 2019) and also compared to Tahiti acid lime on various rootstocks by Rodrigues et al (2018). This was similar to the performance presented by Costa et al (2021), who worked on orange trees with different rootstocks.…”

Citrus represents one of the main fruit crops grown in the world, highlighting the ‘Tahiti’ acid lime tree. The objective was to compare rootstock varieties combined with this scion to identify those with the best agronomic performance and precocity of production, in addition to Phytophthora gummosis resistance. The experiment was carried out in Capitão Poço, northeast region of Pará, and the following seven rootstock genotypes were evaluated: ‘Sunki Tropical’, ‘BRS O S Passos’, ‘BRS Bravo’, ‘BRS Donadio’, ‘Citrandarin Indio’, ‘BRS Matta’, and ‘LVK x LCR-038’. A randomized block experimental design was used, with three replications and 10 plants per plot. The evaluated characteristics were: plant height (m); crown volume (m3); number of ripe fruit per plant; total yield of ripened fruit per plant (kg plant-1); cumulative fruit yield (fruit kg plant-1); and average productive efficiency (fruit kg m-3 of crown). The average productive efficiency was high. For early selection, the best rootstocks in terms of yield, stability and adaptability were Sunki Tropical, BRS O S Passos, and Cintradarin Indio. The fruit number had the greatest direct effect on fruit yield, and crown pruning was directly harmful. Further studies to understand the complex interaction of G x E for BRS Donadio and Sunki Tropical should be carried out.

“…Não foram encontrados na literatura dados de massa média de frutos da 'Pêra' produzidos nas regiões de clima subtropical do sul do Brasil. Porém, em Cocal do Sul/SC, a laranjeira 'Hamlin' produziu, do segundo ao sétimo ano, frutos com massa média de 124,8g (KOLLER et al, 2000), valor inferior ao observado para os pomares 1 e 2, tanto para massa média global quanto para as categorias G e M. A média dos casos em estudo é também superior à de todos os clones de 'Pêra' testados em Cordeirópolis/SP por Schinor et al (2009), mas semelhante ao observado em Londrina/ PR por Giampani et al (2016) em vários clones de 'Pêra'. Dessa forma, não se pode afirmar que a massa média dos frutos em Chapecó e Xaxim é pequena, mas sim semelhante à das regiões tropicais.…”

Resumo-O cultivar de laranjeira 'Pêra' (Citrus sinensis (L.) Osb.) é o mais importante no Brasil, devido à sua boa adaptação no sudeste do país e à qualidade do seu suco. Porém, como é suscetível à tristeza dos citros, doença que é mais severa em climas frios-como o subtropical, que ocorre no sul do Brasil-, seu cultivo nessa região é limitado. O objetivo deste trabalho foi avaliar a potencialidade da laranjeira 'Pêra Bianchi' para o cultivo em Santa Catarina. Foram avaliados dois pomares adultos de 'Pêra Bianchi' localizados no oeste do estado. Durante duas safras, avaliaram-se o tamanho das plantas, a produção de frutos e a qualidade dos frutos (tamanho e características do suco). A laranjeira 'Pêra Bianchi' apresentou produtividade satisfatória, média equivalente a 42 e 45 t ha-1 , e qualidade de suco adequada aos padrões de mercado. Porém, grande parte dos frutos produzidos não apresentou tamanho adequado à comercialização como fruta de mesa. Foi observada considerável variabilidade entre plantas no mesmo pomar quanto à produtividade e tamanho dos frutos. Termos para indexação: Citrus sinensis (L.) Osb.; tamanho de frutos; tristeza dos citros.

“…In our studies, stem pitting symptoms were more severe in trees exposed to colder conditions. These conditions may favor viral replication and symptoms expression (Dodds et al 1987;Koller and Soprano 1998;Carvalho et al 1997;Salibe et al 2002;Giampani et al 2016).…”

“…A population of genetically related variants of the virus is likely to be involved in CTV infections (Ayllón et al 1999;Kong et al 2000;Rubio et al 2001). Furthermore, the development of citrus tristeza symptoms depends on the rootstockscion combination, aggressiveness of the CTV complex, and environmental conditions, particularly temperature (Bennett and Costa 1949;Carvalho et al 1997;Salibe et al 2002;Giampani et al 2016).…”

“…The most common symptoms of citrus tristeza in 'Pêra' sweet orange grafted on rootstocks tolerant to CTV are stem pitting in the trunk and branches, small and chlorotic leaves, undersized and deformed fruits, and general stunting of the citrus trees (Bennett and Costa 1949;Souza and Müller 2006;Moreno et al 2008;Dawson et al 2013Dawson et al , 2015. Furthermore, the severity of stem pitting in trees of 'Pêra' sweet orange has also been associated with poor agronomic performance regarding vegetative vigor and yield (Baba et al 2014;Giampani et al 2016).…”

The aggressiveness and genetic diversity of the Citrus tristeza virus (CTV) infecting sweet orange 'Pêra Bianchi' (Citrus sinensis) trees were evaluated under the environmental conditions of the state of Paraná, Brazil. Disease severity was assessed based on stem pitting symptoms in the citrus trees, while genetic diversity was determined by sequencing the virus coat protein (CP) gene. Stem pitting symptoms were less severe in trees maintained under greenhouse conditions and field experimental plots in the municipalities of Paranavaí and Umuarama, where the temperature is higher. In contrast, the most severe stem pitting symptoms were observed in trees from experimental orchards established in colder areas (i.e. municipalities of Arapongas, Cascavel and Londrina), suggesting a temperature effect on symptom development. Analysis of CP sequences indicated intra-and interspecific diversity of the CTV complex for most of the trees included in this study. Recombination analyses of the CP gene also allowed to identify recombinants with parentals related to PIAC-5, a mild isolate, and 1BL-3, found in trees from a field plot in Londrina. The CTV complex infecting 'Pêra Bianchi' trees under field conditions showed a high degree of genetic diversity, implying the possibility of multiple infections or even a dynamic rearrangement of the genotypes into different CTV complexes under the environmental conditions of the state of Paraná.
