“…The success of P. dubium (high survival rate) may be related to the high phenotypic plasticity, related to high irradiance and low incidence of pests and disease in this species [32][33][34]. In addition, P. dubium is a pioneer species that presents a pronounced growth of the root system and, consequently, develops a larger leaf area and a balanced aerial part [35].…”

Forest restoration in Brazil has gained relevance in the country’s environmental agenda, due to the need for forest recovery of large liabilities of existing forests and participation in several international vegetation restoration agreements. However, forest restoration management faces challenges, it being necessary to create a database of species-level performances to increase the success of these projects. The objective was to evaluate the survival and growth of five Atlantic Forest native species (Anadenanthera macrocarpa; Ceiba speciosa; Cytharexyllum myrianthum; Hymenaea courbaril; and Peltophorum dubium) in plastic bags (1177 cm3) and tubes (180 cm3). Ninety seedlings (18 of each species) were planted per container. Plant performance in the field consisted of evaluating the increase in the diameter and height of seedlings of the native forest species. Diameter at soil level (DSL) and plant height (H) were measured at 42 months after transplanting, and the monthly periodic increments (MPI) of the DSL and H were calculated. Plant survival (SV) of seedlings was affected by the type of container, registering the highest SV rates in those planted in plastic bags. Cytharexyllum myrianthum and H. courbaril presented high SV rates in tubes. The growth rate of the species at 42 months differed according to the containers tested. Cytharexyllum myrianthum presented the lowest SV rates (16.7–27.8%), regardless of the container used in this experiment. Ceiba speciosa was sensitive to the reduction in size of the container, showing low SV in tubes (27%) compared with plastic bags (61%); i.e., this species did not tolerate conditions with root growth restriction. Anadenathera macrocarpa and H. courbaril showed no differences in SV, regardless of the container used. The results assist the production of native species of the Atlantic Forest, reinforcing the need to understand performances in the field at the species level.

The objective of this work was to evaluate the potential of native species used in ecological restoration in Brazil (Peltophorum dubium -canafístula, Hymenaea courbaril -jatobá, Jacaranda cuspidifolia -jacarandá, and Enterolobium contortisiliquum -timboril) as raw material for the supply of sawmills. Due to the difficulties in sampling trees of native species, four trees per species were collected, at age of 12 years, in a legal reserve area. The sampled trees were evaluated as being quite characteristic of trees of the same genetic material. The trees' diameter was measured, the percentage of bark and the taper were measured, and the lumber yield of each species was calculated. The boards were air-dried. Based on the DBH, timboril had the greatest potential for biomass production, but its wood quality was unsatisfactory. To supply raw material for sawmills, in addition to jatobá, we suggest investing in plantations of canafístula and jacarandá.

“…Peltophorum dubium (Sprengel) Taubert é uma espécie nativa popularmente conhecida como canafístula, pertencente à família Fabaceae (XAVIER et al, 2018). Possui tolerância a baixas temperaturas, adaptando-se ao clima subtropical e temperado, fator que favorece sua extensa ocorrência natural, desde o estado da Bahia ao Rio Grande do Sul, sendo encontrada principalmente nas florestas latifoliadas semidecíduas (RAMPIM et al, 2014).…”

A canafístula [Peltophorum dubium (Sprengel) Taubert (Fabaceae)] é uma espécie nativa promissora para a produção de madeira. Assim, para a formação das mudas, a profundidade das sementes e a sua posição de deposição na semeadura são alguns dos vários fatores que exercem influência no seu crescimento e desenvolvimento. O objetivo do presente trabalho foi avaliar a produção de mudas de canafístula, em função da posição da semente no substrato e da profundidade de semeadura. O experimento foi conduzido em casa de vegetação em delineamento experimental de blocos ao acaso, dispostos em esquema fatorial 5 x 3, sendo os fatores constituídos por cinco posições (A – hilo para baixo, B – hilo para cima, C – hilo e “dorso” de lado, D – “dorso” para baixo, E – “dorso” para cima) e três profundidades de semeadura (1, 3 e 5 centímetros), com quatro repetições. As contagens do número de plântulas emergidas foram diárias, do 6.º até o 15.º dia após a semeadura, quando se determinou o índice de velocidade de emergência. Aos 30, 60, 90 e 120 dias após a emergência avaliaram-se: altura de planta, diâmetro do coleto, quociente de robustez por meio da relação altura/diâmetro do coleto, número de folhas, volume radicular, massa seca aérea e das raízes, relação entre a massa seca aérea/raízes e o índice de qualidade de Dickson. O melhor desenvolvimento e qualidade final das mudas de canafístula ocorrem quando as sementes são semeadas na profundidade de 1 cm nas posições C e D ou na profundidade de 3 cm nas posições A, D e E.
