“…Contrarily, totally removing endocarp at 20°C proved to be less efficient, with the highest MGT value (21.95) (Table 3). The knowledge of physic, biometrics, and morphologic characteristics of seeds is essential to understand species ecology and being successful in seedling production for economic or conservation purposes since seeds are the most used propagules for seedling production (Rego et al, 2009;Duarte et al, 2019;Maggioni et al, 2020). Our results related to seed physical characterization were close to those reported in the literature (Maggioni et al, 2020).…”

“…(Lamiaceae), popularly known as "peloteiro", which is a native species occurring in Brazil, mainly in the Mixed Ombrophilous Forest (França, 2003;Harley et al, 2015). The peloteiro tree has great potential for plantations intended for degraded ecosystem recovery (Maggioni et al, 2020;Foladori-Invernizzi et al, 2021); however, there is still a lack of information about the species. Its seeds have a low germination potential because of a physical barrier caused by the endocarp, which prevents water absorption and radicle emission; moreover, there is no germination after 150 days of sowing, and treatments with scarified seeds resulted in 100% of mortality due to the embryo rotting (Maggioni et al, 2020), an issue common to several species.…”

Aegiphila brachiata is a forest native Brazilian species, known as peloteiro, with high capacity for biomass production and resistance to disturbances, having potential use in degraded ecosystems. Seeing the scarcity of studies on the species, we aimed to determine the morphobiometric characteristics of fruits, seeds and seedlings; and evaluate its germination potential. We determined physical characteristics of fruits and seeds, morphological description of seeds, germination stages and seedling development. Germination was in a completely randomized design (factorial scheme), with three temperatures (20, 25, and 30°C) and two methods of overcoming dormancy (partial and total endocarp removal). Fruits are indehiscent, fleshy, with persistent calyx. The pyrene is constituted by endocarp and seeds. Germination is hypogeal, and seedling cryptocotyledonary. Results show that removing the endocarp with the unprecedented methodology used is a suitable method to overcome mechanical dormancy (with 25 and 30°C), showing potential of the method for applicability in several species.

“…According to Small and Degenhardt (2018), hormones can enhance cell division and development of cells, including the structure and functions. Giving hormone in an optimal concentration will stimulate the growth and development of the roots (Akhtar et al, 2015;Okao et al 2016;Maggioni et al, 2020). In addition, there was a correlation between endogenous auxin content and the ability of cuttings to form rooting (Henselova et al, 2002).…”

Kalappia celebica Kosterm is a member of the Fabaceae family and is included as monotypic species. The tree is one of the most important timber because has a high quality of wood, with dark brown color, making K. celebica has great performance thus increasing its economic value. However, its population has decreased with the increase in logging and wood harvesting, mining, and housing. Natural regeneration is also limited due to infrequent flowering periods and fruiting. Therefore, to improve plant material for replanting, it is crucial to do vegetative propagation, such as cutting and accelerating their rooting and growth using a growth regulator. This study aimed to determine the effect of rootone-f as a plant growth regulator on the rooting and growth of K. celebica cuttings. The study was designed using a randomized block design which consisted of 4 (four) treatments. The treatments used were untreated cuttings (control), application of 100 ppm, 200 ppm, and 300 ppm/rootone-f solution. The data recorded were analyzed using an analysis of variance (ANOVA). The results showed that the application of rootone-f treatments had a significant effect. There is a different response between untreated and treated cuttings. The treatment of rootone f produced better rooting and growth than untreated ones. There was a significant increase in the total of primary and secondary roots, length of roots, shoots number, leaf area, shoots dry weight, and roots dry weight of K. celebica cuttings at eight weeks after planting. The highest rooting and growth were reached by 200-300 ppm treatment. Rootone f application with concentrations of 200 ppm is the optimal dose that could be considered to produce high-quality seedlings of K. celebica from cuttings. The success of shoots cutting propagation for K. celebica will provide primary practice of K. celebica cultivation, support juvenile stage bypass, and contribute to conservation efforts for valuable, endemic, and threatened tree species.

“…However, there are di culties in producing seedlings of this high-potential species. Failure to germinate A. brachiata seeds is associated with a physical barrier imposed by the endocarp that prevents radicle protrusion (Maggioni et al 2020). Based on this, vegetative propagation, mainly using the cutting technique, can be an excellent alternative for seedling production (Carpanezzi and Carpanezzi 2006; Oliveira and Ribeiro 2013), ensuring planting uniformity and higher productivity (Xavier et 2013;Wendling et al 2016).…”

To improve the production process of Aegiphila brachiata cuttings, the objective of this study was to evaluate the rhizogenic potential of cuttings from rejuvenated and adult mother plants collected in different seasons; we also characterized anatomically the cutting base, analyzed phenolic compounds and proteins contents, and identified polar metabolites. Two rooting experiments were carried out with cuttings from rejuvenated and adult mother plants, both collected in the four seasons of the year, submitted to treatments with indole butyric acid (0, 2000, 4000, 6000, and 8000 mg L− 1 IBA), and kept in a greenhouse for 45 days. The experimental design was completely randomized in a double factorial scheme for cutting experiments (5 [IBA] x 4 seasons), and for biochemical analyses (2 mother plants x 4 seasons, material collected in the moment of rooting experiment installation and after 45 days); for metabolomic characterization, the 2 mother plants were evaluated only at summer experiment installation. Propagules from rejuvenated mother plants collected in the spring are more viable and indicated to produce A. brachiata cuttings (25.25% rooting), not requiring the use of IBA. Despite the higher rooting rate of cuttings from rejuvenated mother plants, there are no anatomical differences from adult mother plants cuttings. The highest contents of phenolic compounds were observed in propagules from rejuvenated mother plants in spring, indicating a positive effect of these compounds on the rhizogenic process. Maleic acid, 2-hydroxy-glutaric acid, mannose-6-phosphate, ribonic acid, glycine, and phosphoric acid were found in higher concentrations in cuttings from rejuvenated mother plants, with possible beneficial physiological effects on cuttings rooting.
