Abstract: Citrus plants are part of one of the most important fruit crops in the world in subtropicais countries. It is one of the most popular sources of tasty fruits that provide multifunctional bioactive compounds such as folic acid, fiber, vitamins and essential oils. The use of rootstock is important in citriculture to ensure a more uniform production and maintain the genetic characteristics of superior cultivars, adding agronomic value. However, the compatibility between the scion and the rootstock is necessary for the success of its cultivation. The rootstock influences the phenotype of the plants, their productivity, size and precocity, as well as the quality of their fruits and their resistance to abiotic and biotic stresses. Therefore, one way to overcome the problems caused by Phytophthora diseases would be the use of scion/rootstock combinations tolerant to the pathogen. In this sense, the objective of this study was to evaluate the correlation between phenotypic attributes of plants with 'Pera' orange [Citrus × sinensis (L.) Osbeck] and 'Tahiti' acid lime [C. × Tanaka latifolia (Yu.) Tanaka] grafted onto 'Indio' citrandarin ('Sunki' × 'English' trifoliata) rootstock inoculated with Phytophthora citrophthora. The study of correlation between phenotypic attributes contributes to plant breeding programs, in the selection of scion/rootstock combinations with desirable traits. The experiment was carried out in a greenhouse at Embrapa Mandioca e Fruticultura, in the municipality of Cruz das Almas, BA. The experimental design was completely randomized (DIC) with nine replications. The correlated characters were plant height (cm), diameter of the rootstock stem (mm), number of leaves and size of the lesion caused by P. citrophthora (mm2). The plants were inoculated with a disk of culture medium containing the mycelium of P. citrophthora, taken from colonies cultivated on eight-day-old carrot-agar medium, kept in a B.O.D greenhouse at 25 ºC and 24 h of light. The discs were placed under the rootstock stem bark, this area was protected for about 15 days with moistened cotton and covered with adhesive tape. Lesion size evaluations were performed 60 days after inoculation, measuring the percentage of injured area under the bark in pixels using the ASSESS program. The data obtained in the phenotypic evaluations were submitted to Pearson's correlation coefficient analysis at 5% probability of error, with significance at the 1% level by the t test, using the Rcmd package in the R software (R Core Team Development, 2024). The results showed significant correlation coefficients between most of the evaluated characters, with exception between the stem diameter and the number of leaves. Of the evaluated characters, the one that presented the highest positive correlation with lesion size was the character plant height (r=0.3782). The highest negative correlation value with lesion size was number of leaves (r= - 0.3802). Thus, it is inferred that these correlations indicated that taller plants with fewer leaves in the scion/rootstock combinations evaluated are associated with larger lesions caused by P. citrophthora.

Este trabalho teve por objetivo selecionar, por meio de técnicas da pesquisa operacional, regimes de manejo de Pinus taeda L. que maximizem a receita com a madeira produzida, considerando diferentes taxas de atratividade. Foi utilizado o software OpTimber?LP® para a otimização florestal, o qual realiza as simulações por meio do software SisPinus®. Os regimes foram compostos por diferentes combinações de sítios florestais, densidades de plantio, regimes de desbaste e idades para corte raso, totalizando 17.760 regimes por sítio. A produção de madeira foi quantificada e valorada mediante classes de sortimento. Custos de plantio, desbaste e colheita foram considerados. O Valor Presente Líquido Anualizado (VPLA) e a Taxa Interna de Retorno (TIR) de cada regime de manejo foram calculados. Como resultado, a densidade de 1.600 plantas por ha otimizou o VPLA para a maioria dos casos. Os regimes otimizados incluíram nenhum ou apenas um desbaste e forneceram VPLA de 2.753 e 158 reais por ha e TIR de 22,9% e 2,9%, para os sítios I e IV, respectivamente. Concluiu-se que o número ideal de desbastes é reduzido em sítios com qualidade inferior, e quanto menos produtivo for o sítio, mais tardio será o ano ideal para o corte raso. A taxa de atratividade é um parâmetro que contribui para a determinação de regimes de desbaste, pois quanto maior for essa taxa, maior deve ser o número de desbastes, bem como mais precoces devem ser suas aplicações |
