“…Drought events that occur in arid and semi-arid regions have intensified due to global warming and intermittent rainfall, which has also affected humid and urban environments (Güneralp et al, 2015;Xu et al, 2019). These events, intense and frequent, accentuate declines on growth and plant yield (Silva et al, 2013;Santos Júnior et al, 2020), with negative consequences for the agricultural sector (Li et al, 2009;Lemos et al, 2014;Güneralp et al, 2015;Ramos et al, 2016). In this perspective, family farming suffers the most from these losses (Li et al, 2009;Lemos et al, 2014;Güneralp et al, 2015;Marengo et al, 2016).…”

Thus, for the development and permanence of agribusiness, it is necessary to adopt techniques that increase the drought tolerance in crop plants (Mahajan et al 2011;Ramos et al, 2016;Oliveira Júnior et al, 2019).…”

The aim of this work was to determine if the discontinuous hydration of A. squamosa seeds benefit its seed germination and if the seedlings from these seeds have a greater tolerance to water deficit through the analysis of growth parameters. The experimental design was a completely randomized, in a 4x3 factorial, with four HD cycles in seeds (zero, one, two and three) and three water treatments (control with daily watering, and cycles of five and ten-intervals days between watering). Plant height, stem diameter, number of leaves, dry biomass, root/shoot ratio, leaf area, specific leaf area, and leaf area ratio were evaluated. Discontinuous hydration treatments benefited germination and promoted a better growth of the seedlings under water deficit cycles. The application of three HD cycles increased plant height, stem diameter, number of leaves, leaf area and dry matter of the seedlings compared to the other cycles. On the other hand, water suppression caused a reduction in the growth of A. squamosa, especially at ten-day intervals between watering. HD cycles in the seeds improved drought tolerance in the seedlings, mainly when three HD cycles are applied to the seeds, suggesting this is a good technique to produce seedlings better tolerant to environments with reduced water availability.

Mid-season sweet oranges for fresh and processing markets in Brazil

et al. 2021

View full text Add to dashboard Cite

Pera sweet orange (Citrus sinensis L. Osbeck) is the most important mid-season sweet orange cultivar in Brazil, not only because of its desirable fruit quality for both juice processing and the fresh fruit market, but also because there is a lack of adequate mid-season alternative sweet orange cultivars. This study aimed to evaluate the horticultural performance of other sweet oranges in an attempt to identify similar or superior selections to the standard cultivar, Pera IAC sweet orange. Seventeen sweet oranges selections, including the standard Pera IAC, were budded on Sunki mandarin [C. sunki (Hayata) hort. ex Tanaka]. The experiment was planted in 2007, using 12-month-old nursery trees, with 6.5 × 2.5 m spacing in the Southern region of São Paulo state, Brazil. The experimental orchard was maintained with standard commercial management practices, and without supplementary irrigation. Data collection started three years after planting and was carried out until seven years after the experiment had been installed. Vegetative growth, plant yield, fruit drop, fruit quality, and fruit maturation regressions were assessed. Averages of the alternative selections were compared with those of the standard cultivar by Dunnett test. Performance indexes were calculated in order to identify potential superior selections for the fresh fruit market and for juice processing. Results indicated significant differences among the selections evaluated when compared with the standard cultivar, suggesting better alternatives to be exploited. Five selections (Biondo, Finike, Pera Alexandre Maróstica, Seleta Rio, and Vaccaro Blood) offered superior performance in terms of attributes required for the fresh fruit market, while one selection (Pera Alexandre Maróstica) was superior for juice processing traits. These alternatives to Pera IAC represent an opportunity for more efficient and productive scions with higher fruit quality, and with a slight shift within the mid-season harvest time of sweet oranges in Brazil.
