“…Generally, these variables increased in the rainy seasons and decreased in the dry seasons, in contrast to the other fruit trees. This response by the caja fruit trees can be explained their deciduous habit (abscission of leaves and small branches) during periods of drought (SOUZA et al, 2012) . Consequently, the canopy provided less shade during the dry Ciência Rural, v.53, n.12, 2023.…”

Growth and light environment of fruit trees in silvipastoral systems for rearing of dairy herds

et al. 2023

Silvopastoral systems can have animal welfare and sustainability benefits because trees continually remove carbon from atmosphere, reducing greenhouse effects. Thisstudy identified the most promising fruit trees for inclusion in silvopastoral systems to dairy cattle calves. This experiment was conducted at EmbrapaAgrossilvipastoril, Brazil, between 2014 and 2018. Five silvopastoral systems with fruit trees and ‘Tifton-85’ grass were designed to evaluate tree growth and light environment under the canopies. Data were analyzed using SAS® and PDIFF (P < 0.10). Caja fruit trees had the greatest tree height (5.4 m) and trunk diameter (23.4 cm), while acerola fruit tree had the smallest (1.8 m and 8.3 cm, respectively). At 42 months (drought 2017), caja, cashew, and guava trees had similar heights. Guava trees had the highest light interception (89.3%), both cashew cultivars provided medium levels of shade (50 to 60% LI) and with greater constancy between the rainy and dry seasons. The systems that showed increased light interception during the drought period were those with CCP76 in 2017 and EMB51 in 2018. Higher incidences of wavelengths of the spectral composition of light occurred between the rainfall (2015) and drought (2017) periods, and greater differences in the ratio of red:far red in 2015. By 2018, there were no more differences between the rainy and dry seasons for the spectral composition of light under the tree canopies. Cashews and guava trees have adequate growth and light environment to support silvopastoral systems but Caja and acerola fruit trees showed limitations.

“…Grafting is another viable propagation technique for this genus, especially cleft grafting (BASTOS et al, 2014;LIMA FILHO;SANTOS, 2009), due to its efficiency for most fruit species that are propagated by this method (GÓES et al, 2016). In addition to reducing the juvenile phase or homogenizing commercial orchards, grafting is justified by the possibility of adapting the rootstock to the environment, providing resistance to phytopathogens, tolerance to water stress, and early production (LIMA FILHO;SANTOS, 2009;SOUZA et al, 2012;WARSCHEFSKY et al, 2016).…”

Efficiency of Vegetative Propagation of Cajá-De-Jabuti Under Concentrations of Indolebutyric Acid and Grafting Methods

et al. 2021

The objectives of the tests were to evaluate concentrations of indolebutyric acid (IBA) combined with different types of cuttings and grafting methods on the vegetative propagation of cajazeira-dejabuti (S. testudinis). The experiment with stem cuttings was conducted in a greenhouse with an intermittent misting system. The experimental design was completely randomized in a 5 x 6 factorial arrangement consisting of five cutting types: apical, medial, basal, stratified, and tanchan, and six IBA concentrations: 0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg kg-1, with four replications of ten cuttings. The experiment with the root cuttings followed a randomized block design composed of six IBA concentrations (0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg kg-1) with four replications, evaluating after 120 days the percentages of live, sprouted, rooted, and calloused cuttings, and the number and dry mass of roots and sprouts. Five grafting methods (chip budding, shield budding, cleft grafting, wedge grafting, and splice grafting) were tested by evaluating the graft success and sprouting percentages at 30 and 60 days after grafting, respectively. Statistical analyses were performed using the Kruskal-Wallis non-parametric test. The IBA concentrations of 0, 2,000, 3,000, and 5,000 mg kg-1 increased the number of sprouts in tanchan cuttings. The tanchan cuttings showed the highest survival and percentage of sprouts regardless of the IBA concentration. The IBA concentration of 2,200 mg kg-1 promotes higher rooting rates in root cuttings. Splice grafting provides higher graft success and sprouting rates.

“…O gênero Spondias também pode necessitar de porta-enxerto adaptado ao ambiente, seja pela resistência a doenças, tolerância a estresse hídrico ou precocidade de produção (LIMA FILHO;SANTOS, 2009;SOUZA et al, 2012;WARSCHEFSKY et al, 2016). Lima Filho e Santos (2009) avaliando o umbuzeiro como porta enxerto, observaram diferentes percentagens de pegamento do enxerto de cajá-manga (25%), cajá (66,7%), ceriguela (85,7%), umbu-cajá (88,9%) e umbuguela (100%), com início de produção após o transplantio de dois anos para ceriguela e cajá-manga e cinco anos para as demais espécies.…”
