“…The pots were filled with the Basaplant® commercial substrate and with single superphosphate fertilizer (6 g L -1 ), limestone (30 g L -1 ) and Osmocote® (6.6 g L -1 ) in the 14-14-14 formulation. Throughout the experiment, the plants were fertilized with 7.6 g urea, 24.7 g single superphosphate and 2.8 g potassium chloride per pot, which were split into three applications at 14-day intervals (Biazatti et al, 2018). Foliar fertilization with Bordeaxu mixture was performed every two weeks.…”

“…The mini-cuttings strategy has provided high rooting rates in Psidium species (Altoé et al, 2013(Altoé et al, , 2011a, which was confirmed in the present study. According to Biazatti et al (2018), the summer was the best time for rooting. Altoé et al (2011) found that 'Cortibel 1' minicuttings had the lowest rooting percentages in the months of June and November.…”

“…This approach, first applied in the propagation of forest species (Dias, Oliveira, Xavier, & Wendling, 2012;Ferriani, Zuffellato-Ribas, & Wendling, 2010), has also been successfully used in the propagation of guava and Cattley guava (Psidium cattleyanum) species. As such, it has even been indicated for seedling production (Altoé, Marinho, & Freitas, 2013;Altoé, Marinho, Terra, & Carvalho, 2011a) as well as for the multiplication of accessions for use in breeding or in the recovery of degraded areas (Biazatti, Marinho, Arantes, & Guilherme, 2018;Altoé, Marinho, Terra, & Barroso, 2011b).…”

The viability of the mini-cutting technique requires seedling regrowth ability and continuous propagule production. It is hypothesized that the application of gibberellic acid (GA) can stimulate vegetation and increase the production of mini-cuttings. The aim of this study was to increase the mini-cutting yield of Psidium guajava (L.) × Psidium guineense (Sw.) (‘BRS Guaraçá’) as a function of foliar application of GA and season of the year. The experiment was laid out in a randomized-block design with split-plots in time, in which the plots consisted of different GA concentrations applied (0, 50, 100, 150 and 200 mg L-1) and the subplots were represented by two application periods or seasons (summer and winter). Four replicates were used, with two plants per plot. After the seedlings were topped, GA was applied at different concentrations and the emerged shoots were evaluated over 30 days. Mini-stump yield was assessed by collecting and evaluating the potential number of mini-cuttings. Shoot length and mini-stump yield increased linearly with the increasing GA concentrations during the summer. In the winter, this response was quadratic, with optimal concentrations estimated at 65.3 mg L-1 for shoot length and 76 mg L-1 for mini-stump yield. The GA concentration of 200 mg L-1 provided shorter internodes in the summer, whereas in the winter the use of GA did not interfere with this trait. The increasing applications of GA induced a linear increase in stem diameter at both seasons of the year. Gibberellic acid did not interfere with the rooting of the mini-cuttings. The highest rooting percentage occurred in the summer, with an average of 95%. In the winter, this value was 77.2%, demonstrating that mini-cuttings are a promising technique for ‘BRS Guaraçá’. Foliar spraying of GA promoted an increase in mini-cutting production, without interfering with their rooting.

“…Therefore, vegetative propagation through root cuttings is one of the alternatives that allow the anticipation of the reproductive stage, reduces the juvenile period of the plants and ensures that their characteristics will be maintained (BIAZATTI et al, 2018). Few researches are using in vivo propagation of Campomanesia in the literature, but its use may be an alternative for the production of clonal nursery trees since great results have been obtained for other species and contributed to fast reproductions of new progenies (KOUAKOU et al, 2016).…”

Cytokinin induces the development of gabirobeira root cuttings

et al. 2021

The gabirobeira is a species native to the Brazilian Cerrado with potential for use in cropping systems. This study evaluated the effect of the cytokinin 6-benzylaminopurine (BAP) on root cuttings of gabirobeira (Campomanesia adamantium). The plant material was obtained from gabirobeira progenies of one and two-years-old. The cuttings were segmented in 5 cm length and 1.90 to 3.22 mm diameter, immersed in the following BAP concentrations: 0.0; 1.0; 2.0 and 4.0 mg L-1 for 15 seconds and planted in trays containing the substrate Bioplant®. A complete randomized experimental design was adopted in a factorial scheme 2x4, (cuttings age x BAP concentrations) with fifteen replicates per treatment. After 140 days the number of cuttings with shoots, number of shoots, number of leaves, and diameter of the main root were evaluated. The better development of the cuttings was observed on progenies of two-years-old. The lowest cytokinin concentrations promoted the better emission and number of shoots of the progenies from both ages.
