“…However, for many TGB the transplantation of forbs, subshrubs and shrubs, sometimes even grasses (Le Stradic 2012), is not a promising technique. Alternative techniques must then be developed or applied, such as: transplantation of individual tillers grown in pots from fragmented tufts (du Toit 2009), transplantation of seed‐germinated pot‐grown grasses (de Oliveira et al 2020), cuttings (du Toit 2009; Martins et al 2015), propagation from bulbs (S. Le Stradic, Technische Universität München, Germany) or roots (Silva et al 2011), and micropropagation (Biondo et al 2007; de Oliveira et al 2011; de Souza et al 2015), among others (Fig. 8).…”

Despite growing recognition of the conservation value of grassy biomes, our understanding of how to restore biodiverse tropical and subtropical grassy biomes (grasslands and savannas; TGB) remains limited. Several tools have recently been identified for TGB restoration, including prescribed fires, appropriate management of livestock and wild herbivores, tree cutting and shrub removal, invasive species control, and the reintroduction of native grasses and forbs via seeding or transplants. However, additional research for improved TGB restoration is needed. This article aims to identify ecological research priorities for TGB restoration. The following points are crucial to scale up TGB restoration and meet the challenges of the UN Restoration Decade. Research should focus on: disentangling the reasons why TGB are often undervalued and misunderstood; mapping TGB restoration opportunities; identifying regions where TGB and other biomes naturally exist as alternative stable states; recognizing areas with natural regeneration potential to avoid unnecessary intervention; restoring soil conditions; disentangling factors driving low seed quality, determining germination requirements and developing vegetative propagation techniques for TGB species; disentangling the limiting factors and key ecological processes underlying seedling establishment and community assembly; improving and validating long‐term management to mimic natural disturbance regimes; setting the minimum attributes of desirable TGB in terms of structure, composition, functioning, and resilience; and improving monitoring of restoration outcomes. Such research has the potential to advance theory, policy, and practice in TGB restoration, ultimately resulting in long‐term benefits for people and nature in some of the more neglected ecosystems of our planet.

“…After scarification and asepsis, the seeds of C. ferrea inoculated in vitro, showed high germination rates when compared with other medicinal species such as Croton antisyphiliticus Mart. (Oliveira et al, 2011) and Copaifera langsdorffii Desf. (Noleto & Silveira, 2004) that did not show good and rapid germination in vitro.…”

The objective of this work was to establish a protocol for the rapid in vitro multiplication of Caesalpinia ferrea Mart., aimed at genetic selection and in vitro germplasm conservation. Seeds treated in different sodium hypochlorite solution concentrations were inoculated in Murashige and Skoog (MS) culture medium and maintained in a growth room. After 30 days, sodium hypochlorite at 0.25% concentration resulted in 96.67% survival and 90% germination of the seeds. In the explants multiplication phase three types of medium culture were evaluated supplemented with cytokinins and auxins in different concentrations and combinations. The addiction of 0.1 mg·L-1 Benzylaminopurine (BAP) and 0.1 mg·L-1 Indole butyric acid (IBA) induced 100% of explants with shoots and 32% with root formation, while a complete absence of callus was found. It was observed that 90% of explants derived from the buds developed shoots with 2.73 cm and greater multiplication rate (10.06). The seedlings obtained from in vitro multiplication were acclimated without the presence of roots in different types of substrate. After 60 days, soil substrate was most indicated for acclimatization, showing 63.33% of healthy and uniform plants. In vitro propagation of C. ferrea allows the establishment and multiplication of in vitro seedlings from nodal segments and axillary buds.

“…ex M. Arg. Oliveira et al (2011), for example, found that supplementation gives better results in the number of shoots, but in vitro rooting is superior in culture medium without the addition of plant regulator. Specifically on cassava, better results without BAP supplementation were also verified by Silva, Ferreira and Gato (2015), for rooting parameters and multiplication rate, thus becoming the most suitable for seedling production.…”

The implantation of a model of sustainable development for agriculture can happen with the contribution of the mandiocultura. But for this, culture needs to be strengthened. In vitro propagation is an instrument for this purpose. Micropropagation can provide growers with large quantities of vigorous and healthy cassava seedlings in a short time. The objective of this study was to evaluate the in vitro establishment of four varieties of cassava cultivated in the municipality of Colorado do Oeste, State of Rondônia, popularly known as Arara, Caturra, Cacau Vermelha and Roxinha. For that, an experiment was carried out in the Laboratory of In Vitro Cultivation at the Pole of Technological Innovation of the University of Cruz Alta (UNICRUZ), with a completely randomized design in a 4 x 2 factorial scheme, with 6 replications. The treatments consisted of explants grown in Murashige and Skoog (MS) medium without the presence of growth regulator and MS medium supplemented with of 6-benzylaminopurine (BAP). The results indicate that the average contamination percentage of the explants was 47.19%, differing among the varieties. The best growth response in culture media, in the multiple comparison of means (Scott-Knott's test, 5%), was obtained with MS medium without BAP addition, with significant difference between varieties. Under the conditions of this experiment, it was evidenced that micropropagation is a viable tool for obtaining varieties of interest, with desired phytosanitary qualities, with varietal and large scale authenticity.
