“…This behavior is associated with the limitation of growth and development due to the insufficient supply of nutrients that can result in metabolic alterations in the plant (Taiz and Zeiger, 2013). Some authors verified that the reduction in the volume of the recipient resulted in decrease of dry mass production of seedlings, as it was reported for E. grandis (GOMES et al, 2003), S. terebinthifolius (José et al, 2005) and P. rigida (Gasparin et al, 2015). Nevertheless in the study, we verified that in recipient of smaller size, the seedlings of C. trichotoma showed satisfactory results when lower doses of CRF were applied, while in recipient of greater volume the seedlings required higher quantity of the same fertilizer.…”

This aim of this work was to evaluate the initial growth of Cordia trichotoma seedlings, submitted to different sizes of recipients and doses of controlled-release fertilizer (CRF). This experiment was performed in a greenhouse, and evaluation was done in factorial scheme using two volumes of recipients (110 and 180 cm 3 ) combined with five doses of CRF (0 (controlled); 2.5; 5.0 and 7.5 g L -1 de substrate). The experimental design was completely random with four repetitions each evaluated in factorial scheme. Significant interaction was observed between the size of the recipient and the doses of CRF for most analyzed variables. It indicated that, the quantity of fertilizer to be used depends on the size of the recipient, emphasizing that in the conditions in which the seedlings were produced; the minor volume of substrate does not cause restrictions on growth. It is perceived that most evaluated parameters need higher doses than the maximum provided, in at least one of the recipients, demonstrating elevated nutritional requirement of the species during the nursery phase. The recipient of 110 cm³, combined with the dose of 7.5 g L -1 of CRF is recommended because of the economy of substrate, nursery space and practicality of transportation.

Eugenia involucrata DC. (Myrtaceae) stands out by its ecological potential, and it is indicated in), were evaluated with four repetitions, using completely randomized design. The emergence variables, the emergence speed index and average time of emergence were analyzed, besides the height, stem diameter and relation height/diameter of the stem. The seedlings emergence had the beginning at 77 days after sowing, and it was established at 126 days. For production of seedlings indicated the use of container of 180 cm 3 , allied to the dose of 12 g L -1 of CRF. Nevertheless, considering the long time necessary to the emergence and the slow species growth, the topdressing will be necessary since this fertilizer presents determined time of efficiency.

“…Based on our results, we recommend a dose of 12 g L -1 CRF for the production of quality H. heptaphyllus seedlings, corroborating with the findings of Rorato et al (2016) for Eugenia involucrata seedlings. This dose represents twice of that recommended by the CRF manufacturer, and is higher than indicated for other native species, such as Anadenanthera colubrina (Brondani et al, 2008), Parapiptadenia rigida (Gasparin et al, 2015) and Cabralea canjerana (Aimi et al, 2016).…”

The present study aimed to characterize the growth of Handroanthus heptaphyllus seedlings in a nursery, planted under different container volumes and doses of controlled release fertilizer (CRF), and to verify whether the responses obtained in the nursery are confirmed in the field. For the production of seedlings in the nursery, three volumes of container (180 and 280 cm3 polypropylene tubes and 500 cm3 polyethylene bags) and four CRF doses (0, 4, 8, and 12 g L-1 of substrate) were used. At 180 d after emergence, height (H), stem diameter (SD), H:SD ratio, shoot dry weight, root dry weight, total dry weight, Dickson Quality Index, leaf area, root length, and fluorescence of chlorophyll a were evaluated. The same treatments were evaluated again in the field 540 d after planting, and the survival, increase in H and SD, as well as shoot dry weight, leaf area, chlorophyll fluorescence, and chlorophyll index (a, b and total) were measured. In the nursery, seedlings of H. heptaphyllus responded positively to the volume of the container, as well as the base fertilization using CRF. However, when planted in the field, the plants that received the best nutritional conditions in the nursery showed good performance and was favored in the field. Thus, in the production of quality seedlings, the use of containers of the type polypropylene tubes with 180 cm3, and basic fertilization with 12 g L-1 of CRF conditions that enable growth of H. heptaphyllus in the field are recommended.
