“…However, contrary results were reported during the autumn season by Pereira et al (2017), when cuttings were supplemented at a maximum IBA concentration of 3200 mg L -1 , and it was obtained a 80.71% survival for C. adamantium and a 100% survival for C. pubescens. These results showed that for the same species, discordant responses can occur due to concentrations and biological material, making it important to define the ideal concentration, and the most favorable time for species propagation, validating the importance of studys related to propagation vegetative by cuttings.…”

“…Pereira et al (2017) did not observe calogenesis in the cuttings of C. adamantium and C. pubescens demonstrating the variability for the same species. According to the observed data, callus formation in both species demonstrated tissue competence for the dedifferentiation process, although insufficient for root induction.…”

“…Conversely, Pereira et al (2017) observed just the occurrence of buds when Campomanesia adamantium and Campomanesia pubescens cuttings received IBA treatment (0, 800, 1600 and 3200 mg L -1 ) by the immersion of cuttings for 15 seconds in solution during autumn. Considering the potential of the species those authors recommended new studies on other seasons and with different concentrations of indolbutyric acid.…”

The propagation of gabirobeira is carried out by seeds. However, the recalcitrance and not tolerance of the seeds to the storage compromise the formation of seedlings. Thus, the propagation by cuttings can be an option, being able to provide significant results in different seasons. The objective of this work was to evaluate the vegetative propagation by stem cuttings of two species of gabirobeira (Campomanesia adamantium and Campomanesia pubescens) associate to indolbutyric acid (IBA) at differents seasons of the year. Cuttings of the two species were obtained in the 4 seasons and concentrations of 0, 2000, 4000, 6000 and 8000 mg L-1 of IBA were used, by immersion in the solution for 15 seconds and sequentially staked on trays containing a sand substrate. Sixty days after experiments were set it was evaluated the percentage of cuttings with shoots, live cuttings, dead cuttings, cuttings with calluses and rooted cuttings. A completely randomized design with 5 treatments, 4 replicates and 8 cuttings per plot was adopted. During the whole experiment, the greenhouse, substrate and cutting leaves temperature was monitored. The use of IBA did not promote adventitious rhizogenesis, but provided a high percentage of survival for the species Campomanesia adamantium and Campomanesia pubescens by stem cuttings during the spring season.

“…According to Hartmann et al (2011), among these hormones, auxins have a direct effect on roots formation in vegetative propagation, as they favor cellular activity and also act in signaling molecules in the development of events for root formation. They are considered the most important substances that promote adventitious rooting, mainly for species that have difficulty in rooting (PEREIRA et al, 2017), with the indole-3-butyric acid (IBA) being the most used auxin to stimulate the rooting of propagules, due to its low toxicity for most species (TRONCO et al, 2015).…”

Mini-cutting technique of tree species is an effective method of maintaining desirable features of plant matrices and uniformity. The objective of the present research was to determine substrate and concentration of indolebutyric acid (IBA) more suitable for mini-cuttings of Carya illinoinensis rooting. The experiment was carried out in a greenhouse with mist, from February to May 2018. The used experimental design was in blocks with a factorial arrangement of 3 x 5, in which three substrates were tested: carbonized rice husk, vermiculite and perlit; and five IBA concentration : 0, 2,000, 4,000, 6,000 and 8,000 mg L-1. The mini-cuttings were apical, produced from seedlings, with eight months of age. Mini-cuttings were made with two leaves cut in half and 8 to 10 cm in length. The use of IBA influenced results obtained with all substrates, except for the variable number of roots, in which only IBA effect was observed. However, higher results were obtained with IBA uses together with substrate carbonized rice husk, obtaining estimated maximum point of 91% of rooted mini-cuttings with 3,957 mg L-1 IBA concentration. For other evaluated variables, except root numbers, it was also observed superior results close to 4,000 mg L-1 IBA concentration with substrate carbonized rice husk. Results indicate the possibility of Carya illinoinensis propagation by mini-cutting technique and as an alternative for this specie plantlets production.

“…Its exploitation is extractive, performed in an inadequate way (Pereira et al 2017). Its use by the industry is incipient (Freitas et al, 2008), but its fruits can be used for consumption in natura, production of sweets (jellies, pans, puddings, sorbets), juices, liqueurs and wine (Pavan et al, 2009).…”

Gabirobeira is a fruit tree native to the Brazilian Cerrado with a good productivity and acceptance by the local population and with good prospects for processing. Even with the growing interest in the industry and its potential use, information on gabirobas is limited. Therefore, the knowledge of the development, the characteristics of fruits and the genetic divergence is fundamental to define actions of domestication and adaptation to the productive system. The objective of this study is to determine the genetic variability of 173 genotypes of Gabirobeira from the Jataí-Goiás germplasm collection based on plant and fruit morphological traits. The evaluations were carried out in two periods, and eleven morphological traits were evaluated. Based on data, we performed statistical descriptive analysis, correlation analysis, estimation of relative importance of traits and cluster analysis using multivariate techniques (Tocher and UPGMA). The results showed variability and, among the genotypes studied, it was verified that the lowest and the highest CV (15.8% and 102.49%) were observed for fruit width and number of branches. The mean values obtained for soluble solids ranged from 6 to 26 ºBrix. The contribution of different traits assessed for variability ranged from 0.10 to 27.55%. The dissimilarity varied from 3.64 to 80.35, with an average of 23.083. Both grouping methods formed 18 groups. These results show that the germplasm collection presents variability, which can be used as a guide for its maintenance with the possibility of exploring this variability in future genetic improvement works.Additional keywords: Campomanesia; germplasm; multivariate techniques.

As avaliações foram realizadas em duas épocas e foram avaliados onze caracteres morfológicos. Com base nos dados, realizaram-se a análise estatística descritiva, correlação, estimação da importância relativa dos caracteres e análise de agrupamento, por meio de técnicas multivariadas (Tocher e UPGMA). Os resultados evidenciam existência de variabilidade e, entre os genótipos em estudo, verificou-se que o menor e o maior CV (15,8%, 102,49%) foram observados para a largura do fruto e o número de ramificações. Os valores médios obtidos de sólidos solúveis variaram de 6 a 26 o Brix. A contribuição de diferentes caracteres avaliados para a variabilidade variou de 0,10 a 27,55%. Já a dissimilaridade var...
