| A propagação do cafeeiro é feita de duas formas: sexuada, que se baseia no uso de sementes, e assexuada, baseada no uso de estruturas vegetativas das plantas, a exemplo do uso das estacas, ou pedaços de seus ramos. No Acre, o processo usual de propagação do cafeeiro, tanto da espécie arabica como canephora, é por semente. Embora a Embrapa já tenha difundido a produção vegetativa por meio de estaca para o café Conilon, da espécie canephora, ainda são poucos os produtores que utilizam esta técnica. Este trabalho trata destas duas formas de produção de mudas de café. |

| Abstract Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production,... |

| The present study was carried in order to evaluate the effect of saline water irrigation with electrical conductivity (ECw) of 0.5; 1.5; 3.0; 4.5 and 6.0 dS m-1, on germination and some growth variables during the seedling formation process of four guava cultivars (Psidium guajava L.): Pentecoste, Paluma, Surubim and IPA B-38. Water salinity inhibited the germination process, plant height, stem diameter, leaf area and dry matter production of roots, stems and leaves, independently of cultivar. After germination, the seedlings did not survive due to saline water effects of ECw 4.5 and 6.0 dS m-1. After 180 days of sowing, the seedlings irrigated with ECw more than 1.5 dS m-1 did not present agronomic quality for planting. Dry matter production sequence of... |

| The baru (Dipteryx alata Vog.) is a native species of Brazilian cerrado, and has been widely used in reforestation, medicine, and food industry. The effects of shading levels, reflective material, and seeding depth on the growth of baru seedlings were investigated in this study. The seedlings were grown in full sunlight, and in three production nurseries constructed with 18%, 30%, and 50% shading screens on growing benches coated or not coated with a reflective material (Aluminet®). The seeds were sown at depths of 2.0 or 4.0 cm in black polyethylene bags of 15.0 × 25.0 cm (1.8 L), filled with substrate formulated from the mixture of sandy soil: bovine manure: vermiculite (5: 3: 2). Each seedling production environment was considered an experiment because... |

| Plant growth regulators and biostimulants have been used as an agronomic technique to optimize the production of seedlings in various crops. This study aimed to evaluate the influence of gibberellic acid and the biostimulant Stimulate® on the initial growth of tamarind (Tamarindus indica L.). The experiments were conducted in a nursery with 50% shading, in a randomized block design with five replications and five plants per plot. Thirty eight days after sowing, the leaves were sprayed seven times a day with 0.0 (control), 0.8, 1.6, 2.4 and 3.2 mL of gibberellic acid L-1 aqueous solution and with 0.0 (control), 6.0,12.0, 18.0, and 24.0 mL Stimulate® L-1 aqueous solution. Stem diameter (SD), plant height (PH), longest root length (LRL), shoot dry mass (SDM),... |

| The study assessed growth and physiological parameters of 'Sunrise Golden' and 'Tainung 01' papaya seedlings grown in 280mL plastic tubes and watered using a low-cost automatic irrigation system adjusted to operate at substrate water tension for starting irrigation (STI) of 3.0, 6.0 or 9.0 kPa. The water depths applied by the dripping system and drainage were monitored during germination and seedling growth. Germination, emergence velocity index (EVI), leaf area, plant height, shoot and root dry weight, stomatal conductance, relative water content (RWC) and relative chlorophyll content (RCC) were evaluated. Soil nutrient levels were determined by electrical conductivity (EC). Water use efficiency (WUE) corresponded to the ratio of plant dry mass to depth... |

| For high technology seedling production systems, nutrition plays an important role, mainly the fertigation with iron chelates to prevent its deficiency. This study had the goal of searching for alternative iron sources with the same nutrient efficiency but lower cost in relation to nutrient solution total cost. An experiment was carried out in 56 cm³-conic-containers tilled with a pine bark/ vermiculite mixed substrate using Fe-DTPA, Fe-EDDHA, Fe-EDDHMA, Fe-EDTA, Fe-HEDTA, FeCl3, FeSO4, FeSO4+citric acid plus a control, and the rootstocks Swingle, Rangpur, Trifoliata and Cleopatra, in a randomized complete block design, with four replicates. Seedlings were evaluated for height, relative chlorophyll index, total and soluble iron leaf concentrations.... |

| The production of forest species that present seedlings with exogenous dormancy is limited by low germination rates, which can be overcome by rupturing or weakening the tegument. This study aimed to evaluate the efficiency of low-cost methods of overcoming dormancy and determine the effect of storage on the seeds of Enterolobium contortisiliquum. Four storage periods were used, freshly collected seeds (0), stored for 6, 12 and 18 months, and four methods were applied, mechanical scarification and immersion in water (EI), mechanical scarification (ES), immersion in water (IM) and control (TE). We obtained the percentage values of seedling emergence (EP) and the mean emergence time (TME). Conductivity and moisture were obtained as indicators of the physical... |

| ABSTRACT Polyembryony is the differentiation and development of multiple embryos in a single seed. This characteristic can provide advantages, as more than one embryo is produced with the same amount of resources, and the probability of establishment of at least one seedling increases. However, sibling seedlings may also increase competition, affecting development and survival. In the present study, the possible advantages and disadvantages of polyembryony were analyzed in the initial establishment of seedlings of Carapa surinamensis (Meliaceae), a tree species that produces monoembryonic or polyembryonic seeds. In this regard, the development of single seedlings was compared with a pair of seedlings emerging from polyembryonic seeds. We compared the... |
