ABSTRACT This research aimed to characterize the biometry of seeds, the morphology of seedlings and to evaluate the initial growth of blue jacaranda trees (Jacaranda mimosifolia D. Don.) in two environments with distinct luminosity. The biometry of 100 de-winged seeds was measured by their length, width and thickness. One hundred seeds were sown into 300 cm3 tubes and seedlings morphology was registered throughout the germination process using digital photographs disposed sequentially according to seedlings age. The initial growth analysis was performed in two environments, full sun and greenhouse, during nine periods, and arranged in a complete randomized design with subplots. The response variables were: number of leaves, plant height, collar diameter, root length, aerial and roots dry weight, and Dickson’s Quality Index (DQI). Biometry results showed seeds 7.09 - 9.26 mm long, 6.74 -9.39 mm wide, and 1.11 -1.89 mm thick. Germination is of hypogealphanerocotylar type, with first root arising six days after sown. Plants at full sun presented larger collar diameters, greater root dry weight and higher DQI as evaluation periods passed by. In conclusion, the biometry of seeds and the morphology of seedlings of blue jacaranda can be used to recognize this species in the field. Plants at full sun presented better development. Seedlings cultivated at full sun can be destined to recuperate forests and degraded areas just 36 weeks after sowed.

The application of Trichoderma fungus can be used to obtain seedlings of higher quality for plantations. The objective of this study was to evaluate the effects of Trichoderma isolates on the germination and initial growth of açaí seedlings. Two trials were set up. In the laboratory, the seeds were inoculated in suspensions prepared with each of the isolates for 24 h, and they were arranged in trays containing filter paper in a completely randomized design with five replicates containing 50 seeds each. For the control, the seeds were submerged only in water. Part of the seedlings resulting from seeds treated and not treated with Trichoderma were transferred to bags containing forest soil and were submitted to seven modes of application of Trichoderma and kept in a nursery. The speed of germination and hypocotyl were not influenced by the biological treatment. The application of the different Trichoderma isolates positively influenced the height, collar diameter, number of leaves, root size, leaf area and root, and aerial part dry mass of the açaí seedlings. The application of the Trichoderma isolate TAM01 on the preplanting substrate and biweekly applications on the postplanting substrate was the combination that most positively influenced the development of açai seedlings.

The aim of this study was to analyze the effect of fruit maturation on the physiological quality of seeds and on the initial growth of carnauba palm (Copernicia prunifera). Propagules were collected from specimens of urban tree growth in Fortaleza, CE, Brazil. The treatments were set up with four replications in a 2x3+1 factorial arrangement; the factors consisted of two color tones of fruit (yellowish-green and dark colored fruit), three types of propagules (whole fruit, pulped fruit and seeds) and an additional control (pre-germinated seed extracted from dark colored fruits) in a completely randomized design. The variables assessed were: percentage of emergence, plant height, stem diameter, dry weight of the shoots and of the root system, and the Dickson quality index. The yellowish-green fruits may be used in carnauba palm propagation if the pulp and the pellicle around the seed are removed. Plants derived from dark colored fruits exhibit greater values for height, stem diameter, dry weight of the above ground part and of the roots. From the Dickson quality index, plants derived from dark colored fruits have a better standard of quality than those from yellowish-green fruits.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

Yellow Passion Fruit

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

ABSTRACT The aim of this study was to evaluate the initial growth of sunflower seedlings under different concentrations of sanitary landfill leachate, considering the feasibility of its use as source of nutrients for agricultural production. Biometric and vigor variables were analyzed through the measurements of collar diameter, shoot height, number of leaves and shoot and root fresh and dry matters, from January to February 2015. The experimental design was completely randomized in a 5 x 4 factorial scheme: five leachate concentrations (0, 40, 60, 80 and 100 kg N ha-1) x four harvest periods (14, 21, 25 and 29 days after sowing), with five replicates each containing two plants. The data were subjected to analysis of variance and polynomial regression, and the results of the last harvest (29 DAS) were compared by Tukey test (p ≤ 0.05). The use of sanitary landfill leachate increased all analyzed variables in sunflower plants when compared to the control plants (without leachate), especially in the treatment of 100 kg N ha-1. There was no inhibitory effect of the leachate on the initial growth of sunflower seedlings under adopted experimental conditions.

O uso de fertilizantes de liberação controlada constitui-se em uma das modernas técnicas na produção de mudas. Porém existem poucos relatos de seus efeitos sobre o crescimento inicial de espécies florestais nativas em área de domínio ciliar. O estudo objetivou comparar os efeitos de diferentes fertilizantes de liberação lenta (FLL) com uma formulação convencional no crescimento a campo de mudas de Anadenanthera colubrina e Tabebuia avellanedae. As mudas foram plantadas com 55 g por cova de Basacote 3M, Basacote 6M, Basacote 9M, formulação 16-8-12, e uma testemunha (sem fertilização). As mensurações não destrutivas incluíam os incrementos em altura, diâmetro do coleto e número de folhas aos 90, 180, 270 e 360 dias após o plantio, e avaliações destrutivas da massa seca aérea e radicular em mudas escavadas aos 180 e 360 dias após o plantio. Os resultados revelaram maior incremento para o diâmetro do coleto e o número de folhas em A. colubrina com FLL, enquanto que mudas de T. avellanedae expressaram maiores respostas em incrementos de altura. As biomassas secas da raiz e aérea não foram influenciadas pela adição de fertilizantes na cova, apresentando apenas diferenças entre as espécies.Palavras-chave:  Crescimento inicial; Anadenanthera colubrina; Tabebuia avellanedae; fertilizante de liberação lenta. AbstractEffects of fertilizers applied to ipe roxo and angico during their seedlings planting. Slow release fertilizer (SRF) is a modern tool for seedling production. However, there are few reports on the effects of its application on initial growth of native forest species planted on repairing areas. The aim of this experiment was to compare the effects of SRF and a conventional fertilizer on initial growth of fields planted with Anadenanthera colubrine and Tabebuia avellanedae seedlings. Treatments included 55 g per planting hole of Basacote 3M, Basacote 6M, Basacote 9M, conventional fertilizer NPK (16-8-12) and a control (no fertilizer). Non destructive measurements included increments of root collar, length, and number of leaves at 90, 180, 270 and 360 days after planting date. Destructive measurements included dried biomass of above and bellow ground tissues, root length, and leaf area of three seedling randomly selected from each treatment. The results showed higher increments in root collar diameter and number of leaves for A. colubrine with SRF while T. avellanedae seedlings showed higher increments in plant height. Differences in relation to above and below ground dry masses were detected only between species at 180 and 360 days after planting date.Keywords: Initial growth; Anadenanthera colubrina; Tabebuia avellanedae; slow release fertilizer.

Physocalymma scaberrimum Pohl é uma espécie nativa que ocorre principalmente no Norte e Centro-Oeste do Brasil, com potencial madeireiro, para arborização urbana e para recomposição de vegetação em áreas degradadas. Considerando a necessidade de conhecimento do seu comportamento em viveiro e da utilização de resíduos agroflorestais como componente de substrato, este estudo teve por objetivo avaliar o crescimento de mudas dessa espécie em substratos compostos por porcentagens de resíduo de açaí (0%, 25%, 50%, 75%, 100%) misturado à terra de mata. O experimento ocorreu em delineamento inteiramente casualizado, com 5 tratamentos (substratos) e 20 repetições. Foi avaliado o crescimento das mudas através da altura, diâmetro do colo, massa seca da parte aérea e radicular e total, e Índice de Qualidade de Dickson (IQD). Houve ajuste de regressão linear e correlação positiva entre altura, diâmetro do colo e massa seca total com as porcentagens de resíduo de açaí. O substrato constituído por 100% do resíduo de açaí proporcionou o maior crescimento das mudas: 32,9 cm de altura, 2,98 mm de diâmetro do colo, 2,003 g de massa seca total e maior IQD (0,1142). Para a utilização com terra de mata, a composição entre 25% e 75% de resíduo também se mostrou possível.Palavras-chave: Resíduos agroflorestais; produção de mudas; espécies florestais nativas; silvicultura. AbstractPhysocalymma scaberrimum seedlings production in substrate composed by different percentages of organic residue of açaí. Physocalymma scaberrimum Pohl is a native species that occurs mainly in the North and Midwest regions of Brazil, with potential for wood production, urban forestry and restoration of vegetation in degraded areas. Considering the need for better understanding of the seedlings behavior in the nursery, and use of agroforestry residue as components of substrate, this study aimed to evaluate the growth of this species in substrates composed by different percentages of açaí residue (0%, 25%, 50%, 75%, 100%) mixed with forest soil. The experiment was set up according to the completely randomized design, with 5 treatments (substrates) and 20 replicates. It was evaluated the growth of seedlings through shoot height, collar diameter, dry weights of shoot and roots and total, and Dickson Quality Index (IQD). A fit linear regression and positive correlation was found out between height, collar diameter and dry weight total dry mass with increasing percentages of açaí residue. The substrate composed by 100% of açaí residue provided the highest mean growth of seedlings: height (32.9 cm seedling-1), collar diameter (2.98 mm seedling-1), total dry mass (2.003 g seedling-1), and highest IQD (0.1142). To use with soil, the composition between 25% and 75% of residue also showed possibility.Keywords:agroforestry residues; seedlings production; native forest species; silviculture.
