“…The superior growth of forest species in plastic tubes of higher volumes is also reported in other studies, like Ferraz and Engel (2011) with three species, Hymenaea courbaril, Tabebuia chrysotricha e Parapiptadenia rigida, comparing tubes of 50, 110 and 300 cm³, as well as in Stüpp et al (2015), with Mimosa scabrella seedlings in tubes of 110 and 180 cm 3 . For Schizolobium parahyba seedlings, Figueiró et al (2017), comparing tubes of 50, 110 and 300 cm³ verified higher growth in height and diameter in the larger volume plastic tube.…”

“…Tubes with higher volumes provides more space and substrate for the seedlings, which enhances the nutrient and water content available for the plants, thereby influencing in the morphological attributes used to evaluate the quality of seedlings (BRACHTVOGEL; MALAVASI, 2010). Studying Schizolobium parahyba, Figueiró et al (2017) concluded that seedlings produced in 300 cm³ tubes had higher growth in shoot height, root collar diameter and biomass, as well as better germination, in comparison with tubes of 50 and 110 cm³. Nevertheless, larger containers demand higher quantities of substrate, thus increasing the seedling production and transport costs (ABREU et al, 2015).…”

Fertilization and containers in the seedlings production and post-planting survival of <i>Schizolobium parahyba</i>

et al. 2019

Fertilization in the production of forest seedlings can vary according to the substrate, container and fertilizer used in the nursery. Controlled release fertilizers (CRF) can be applied to reduce or even to eliminate the need for top-dress fertilization. The CRF doses can vary according to the container volume, considering the different amount of substrate available for seedlings in different containers. This study aimed to evaluate the growth of Schizolobium parahyba seedlings produced in plastic tubes of 110 and 280 cm 3 , with different doses of CRF (15-09-12) (0, 3, 6 e 12 kg m -3 ), as well as the seedlings survival and the initial growth after post-planting in the northern region of Rio de Janeiro state. The study was conducted using a factorial design 2 x 4 (tube volumes x CRF doses), with five repetitions for each treatment. As substrate it was used sewage sludge from urban areas, which was dried in open air beds. The growth of seedlings at nursery was evaluated at 93 days after the transplant, and the survival and initial growth at five and twelve months after planting. The Schizolobium parahyba seedlings showed higher growth in 280 cm 3 tubes and responded positively to the CRF application, where the most efficient dose was 8.3 kg cm 3 for this plastic tube. Twelve months after planting, seedlings from all treatments showed survival below 80%, being under the standard recommended for forest restoration. The mortality of seedlings occurred in consequence of five months of water deficit in a sandy clay loam soil. Considering only nursery data, the combination of 280 cm 3 plastic tubes, with the CRF dose of 8.3 kg cm 3 are recommended to produce Schizolobium parahyba seedlings. ResumoA fertilização na produção de mudas florestais é variável de acordo com o substrato, recipiente e o tipo de fertilizante utilizados. O fertilizante de liberação controlada (FLC) pode ser utilizado visando diminuir ou mesmo eliminar a necessidade de fertilização de cobertura. A dose de FLC aplicada pode variar de acordo com o volume do recipiente, considerando a quantidade de substrato disponível para as mudas em diferentes recipientes. Este trabalho teve como objetivo avaliar o crescimento de mudas de Schizolobium parahyba produzidas com tubetes de 110 e 280 cm 3 em doses crescentes de FLC (15-09-12) (0, 3, 6 e 12 kg m -3 ), bem como seu crescimento inicial e sobrevivência após plantio na região norte do estado do Rio de Janeiro. O estudo foi conduzido em arranjo fatorial 2 x 4 (recipientes x doses de FLC) com 5 repetições para cada tratamento. Como substrato foi utilizado lodo de esgoto de áreas urbanas, submetido a secagem em leitos ao ar livre. O crescimento das mudas no viveiro foi avaliado aos 93 dias após a repicagem e a I Engenheiro Florestal, MSc., Técnico de Silvicultura, Suzano S.A., Rodovia Aracruz x Barra, Km 25, CEP 29197-900, Aracruz (ES), Brasil. gerhard_ Cabreira, G.

“…Figueiró et al (24) also verified positive effects of dormancy-breaking techniques on initial development of Schizolobium parahyba plants, and Martins et al (25) observed better initial corn development in sandy soil. Moreover, Cruz et al (2) already reported C. rotundifolia preference for sandy soils.…”

Chamaecrista rotundifolia is a legume of high yield and nutritional value for livestock; however, it presents high seed dormancy. The aim of this study was to evaluate dormancy-breaking methods and the influence of soil texture on seedling emergence and initial development of C. rotundifolia. The experiment was performed in a greenhouse in a split-plot design with five replications. There were three treatments including dormancy-breaking techniques with immersion of the seeds in (1) hot water at 80°C for 30 s followed by 12 h in water at room temperature (25 °C; HW); (2) water at room temperature (25 °C) for 24 h (EW); and (3) hydrochloric acid (0.05 mol L-1) for 15 min (HA) (4) and a control group with no seed intervention, disposed in the main plots in randomized blocks. Seeds were cropped in two types of soil as subplots. Seedling emergence was evaluated daily to calculate the percentage emergence and emergence speed index. Plant performance was evaluated (21 days after sowing) through measurements of mass and length of components. Chamaecrista rotundifolia showed a high degree of dormancy in the seeds, and the treatment using HW had greater efficiency in seedling emergence (p < 0.01) and emergence speed index (p < 0.05). Total dry mass was superior in sandy soil (p < 0.05). Soil texture and dormancy treatments influenced the initial performance of plants, which performed better in sandy soil.

Parkia multijuca Benth. is one of the Forest species that occurs in the Amazon region. The aim of the this study was evaluate the development of seedlings of Parkia multijuga in differents shading and container volume in nursery. The experimental design was a randomized block design in 4 x 4 subplotplot (4 shadings and 4 containers volumes). The shading was 0, 30, 50 and 70% and containerv olumes 110, 180, 290 and 400 cm³. The diameter, root drymass, shootdrymass, total dry mass and the Dickson quality índex of the seedlings increased proportionally with container volume and with the availability of light. The conduction of the seedlings in full sun and container volume 400 cm³ favors the development of P. multijuga quality seedlings and 70% shading should not be used in nurseries to produce P. multijuga seedlings.
