“…According [ 32 ], one of the difficulties for propagating Jatropha curcas L. through cuttings is that only fine roots originate in the cuttings, which gives the plants reproduced by this method less wind resistance. However, it is known that several factors can influence the proper development of plants propagated through vegetative reproduction, such as carbohydrate reserves, plant hormones, and mineral nutrients [ 37 ]. In this sense, mineral nutrition is one of those crucial factors necessary for the healthy development of productive plants.…”

Even though it is a forest native plant, there are already several studies evaluating the small genome of Jatropha curcas L., which belongs to the Euphorbiaceae family, and may be an excellent representative model for the other plants from the same family. Jatropha curcas L. plant has fast growth, precocity, and great adaptability, facilitating silvicultural studies, allowing important information to be obtained quickly, and reducing labor costs. This information justifies the use of the species as a model plant in studies involving the reproduction of native plants. This study aimed to evaluate the possibility of using Jatropha curcas L. as a model plant for studies involving native forest plants and establish possible recommendations for the vegetative propagation of the species using hardwood cuttings. The information collected can be helpful to other native forest plant species, similar to Jatropha curcas L. To this end, the effects of hardwood cutting length (10, 20, and 30 cm) and the part of the hardwood cuttings (basal, middle, and apex) were evaluated. Moreover, the influence of immersing the hardwood cuttings in solutions containing micronutrients (boron or zinc) or plant regulators (2,4-D, GA3) and a biostimulant composed of kinetin (0.09 g L−1), gibberellic acid (0.05 g L−1), and 4-indole-3-butyric acid (0.05 g L−1). The experiments were carried out in duplicates. In one duplicate, sand was used as the substrate, and rooting evaluations were made 77 days after planting. In another duplicate, a substrate composed of 50% soil, 40% poultry litter, and 10% sand was used, and the evaluations of the saplings were performed 120 days after planting. The GA3 solutions inhibited the roots’ and sprouts’ emissions, while immersion in 2,4-D solution increased the number of primary roots at 77 days after planting. The hardwood cuttings from the basal part of the branch had the best results for producing saplings.

“…Later, the mini garden was utilized to produce miniature pine cuttings (Xiang et al, 2003). Currently, new species have shown promise for using this technique to efficiently control the environmental, phytosanitary, and nutritional conditions of parent plants (Oliveira et al, 2019;Packialakshmi and Sudhagar, 2019;Santos et al, 2020;Lowe et al, 2022;Gazzana et al, 2024).…”

The rubber tree (Hevea brasiliensis) is an important forest species that yields natural rubber. Traditionally, rubber tree grafts are cultivated in clonal gardens on soil, which necessitates enormous acreage. However, this approach is not only inefficient in terms of productivity, but it also has nutritional and water control constraints. A tiny clonal garden with a balanced fertilizer treatment is an approach that has previously been employed for other species. To apply this same system to the rubber tree, the goal was to investigate the effects of applying macro and micronutrients via fertigation on the productivity of a mini rubber tree clonal garden, as well as to assess the efficacy of using green stems produced under these conditions in three grafting techniques. Five dosages of macro and micronutrients were administered to grafted rubber tree seedlings (clone ‘RRIM 600’ on ‘GT1’) before transplanting them into plastic pots. A totally randomized design was adopted, with five treatments and ten replications, each with two plants per pot, for a total of twenty plants per treatment. The shoot apex was cut after 105 days, and the green stems measuring more than 20 cm were harvested throughout the course of a year. The number of stems was highest in the months of January to March 2014, after 135 days, reaching 3 green stems per plant-1 per month-1, and productivity increased up to an estimated electrical conductivity of 1.64 mS cm-1. Nutrition was found to boost the output of the rubber tree clonal mini garden as well as the survival of grafts after grafting. The tiny clonal garden is a potential method for getting more vegetative rubber tree propagules.

“…It propagates from seed. This way, the viability is subjected to insect attacks, such as that by Troezon championi beetle, to supraannual fruiting, and to difficult vegetative propagation (Carvalho et al, 2003;Brasil, 2014;Santos et al, 2020).…”

The objective of this work was to establish an efficient protocol for the in vitro organogenesis of Dalbergia nigra. For this purpose, 30-day-old seedlings were sectioned at their cotyledonary nodes and nodal segments. These materials were cultivated in a medium with different combinations of the 6-benzylaminopurine and thidiazuron cytokinins. After 60 days in a growth chamber set at 27°C and a 16-hour photoperiod, growth characteristics were analyzed. Explants from the cotyledonary nodes show a greater morphogenetic potential, regardless of the addition of cytokinins. Cotyledonary nodes in the medium supplemented with 2.22 µmol L-1 BAP show the best combination for the in vitro propagation of D. nigra.
