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.

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.

One of the main stages in the production system of a crop is the production of quality seedlings since it influences the plants' final performance in the field and their production. The study aimed to evaluate different nutrient solutions in the production of Cambuci pepper seedlings. The design used was a complete randomized design, with six treatments corresponding to the nutrient solutions proposed for the pepper crop by Castellane and Araújo, Claudio Roberto, Hoagland, and Arnon, besides the commercial products Plenan® and Biobokashi®, and a control treatment without fertilization, with six replications. The final evaluation was carried out 45 days after sowing. The following variables were analyzed: stem diameter, plant height, leaf dry matter, shoot dry matter, the number of leaves, relative chlorophyll index ("Spad"), and Dickson quality index. The seedlings subjected to the applications of Claudio Roberto and Hoagland and Arnon solutions have the highest heights and number of leaves, the largest stem diameter, shoot dry matter, leaf area, and Dickson quality index with 2.60 and 2.51 mm, 0.54 and 0.62 g, 38.64 and 41.91 cm2, and 0.107; 0.097, respectively. The Hoagland and Arnon nutrient solution provided the best characteristics to produce Cambuci pepper seedlings.

The research was conducted in the nursery of the National Intercultural University of Amazonia, whose objective was to use effective microorganisms with plant protection ceramics in the initial growth of Theobroma cacao, "common cocoa". The experiment was conducted through a completely randomized design (DCA), with 5 treatments, 10 repetitions and 50 experimental units. The treatments were: T1 (Control); T2 (100 ml of efficient microorganisms (EM) + 20 g of phytoprotective ceramic (CF)); T3 (200 ml of MS + 20 g of CF); T4 (300 ml of EM + 20 g of CF) and T5 (400 ml of EM + 20 g of CF). As a result, the T3 treatment obtained better growth value in height, diameter and specific leaf area with: 25.56 cm, 6.86 mm and 90.77 cm2 / g respectively, compared to the control that reached 19.98 cm. 5.49 mm. 49.32. Regarding the quality indexes, the ratio of aerial dry biomass / dry root biomass (R BSA / RBSR), lignification index (IL), robustness index (IR) and Dickson quality index (DQI), did not show significant differences between the treatments, but the T3 had higher value over the IR with 3.76, the R BSA / RBSR with 2.45 and DQI with 0.85, and the T4 had greater value in the IL with 33.68.

ABSTRACT There is an increasing use of poultry litter in seedling production. However, studies regarding the effect of different particle-size litter on plant growth are still scarce. This study aimed to evaluate the growth of Moringa oleifera Lam. fertilized with poultry litter doses (0 g dm-3, 40 g dm-3, 80 g dm-3 and 120 g dm-3) with distinct particle sizes (1 mm and 4 mm), with four replications. The following variables were evaluated: plant height; root and stem diameter; leaf, stem, shoot and root dry matter mass; shoot/root dry matter mass ratio; and the Dickson quality index. There was no influence of the particle size on the studied variables, except for plant height. The root diameter decreased with the increase of the poultry litter doses. The accumulation of dry matter mass from the shoot and root increased with the increase of poultry litter doses up to 120 g dm-3. A linear increase of the Dickson quality index, relatively to days and poultry litter doses, was observed. It is recommended to apply 80 g dm-3 of poultry litter to fertilize M. oleifera plants, independently of the granulometry used.

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.

Areca nut is widely used as industrial raw material, both for health and cosmetics and as a source of renewable energy. This study aimed to examine the combination of seed bombatriconditioning and LEISA fertilization treatments that were effective in increasing the growth of areca nut seedlings. The research was carried out in the Wua-Wua Kendari Village, from March to July 2021. The study used a split-plot design with a completely randomized design (CRD). The main plot is seed biomatriconditioning treatment which consists of 3 treatments. While the subplots were fertilized with the LEISA technique which consisted of 6 treatments so that 18 treatment combinations were obtained with 3 replications. Observations were made on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of shoot. Observational data were analyzed using analysis of variance, followed by the DMRT α0.05 if there was a significant effect. The results showed that seed biomatriconditioning treatment with rhizobacteria integrated with the LEISA technique was able to increase the growth of areca nut seedlings. The integration between L1R biomatriconditioning and the application of organic plus fertilizer + 100% inorganic fertilizer showed a better growth performance of areca nut on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of betel nut which were significantly different with control and application 100% inorganic fertilizer, but not significantly different from organic plus fertilizer, organic plus fertilizer + 50% inorganic fertilizer and organic plus fertilizer + 25% inorganic fertilizer. As a conclusion, pre-planting seed treatment with L1R biomatriconditioning is very important to increase areca nut seed germination. To increase the growth of areca nut seedlings, further fertilization needs to be done with organic plus fertilizer or a combination of organic plus fertilizer + 25% inorganic fertilizer.

Using residues generated in agriculture to produce seedlingsis an economically interesting alternative, besides being a way to reduce the environmental impacts caused by their inadequate disposal. This study aimed to evaluate the potential of using coffee chaff (CC) and organic compost (OC) as substrate components for the production of Formosa papaya seedlings and the potential of grape pomace (GP), a vitiviniculture residue, in the composition of substrates for the production of okra and zucchini seedlings. We carried out two trials in a completely randomized design (CRD): the first had seven treatments and six replicates: T0: 100% commercial substrate Bioplant® (CS); from T1 to T6: increasing proportions of CC and decreasing of CC: 10/90; 20/80; 30/70; 40/60; 50/50 e 60/40%. The second had six treatments and six replicates, with increasing proportions of GP and decreasing proportions of CS: 0/100; 10/90; 20/80; 30/70; 40/60 and 50/50%.In the first trial we evaluated the number of leaves, root length, seedling height, stem diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI) at 59 days after sowing.The second trialwas performed at 12 and 18 DAS and we analyzed the number of leaves, plant height, root length, collar diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI). Variables that met the assumptions of normality and homoscedasticity were subjected to Dunnett’s test. The substrate composed of coffee chaff and organic compost has a high potential to be used as an alternative substrate due to promote better quality of papaya seedlings compared to the commercial substrate. Alternative substrate containing 60% coffee chaff and 40% organic compost is recommended for the production of  Formosa papaya seedlings in tubes. The grape pomace (GP) has a high potential to be used as component in substrate for the production of okra and zucchini seedlings compared to the commercial substrate (CS) only. Alternative substrate composed of 50% GP and 50% CS is recommended for the production of zucchini seedlings, while substrate composed of 10% GP and 90% CS is recommended for the production of okra seedlings.

ABSTRACTThe objective of this study was to test the hypothesis that biochar, applied with cattle manure, promotes better development of seedlings of Magonia pubescens St. Hil. The experiment was conducted at the State University of Mato Grosso, Nova Xavantina, Brazil, in 2011. We used a completely randomized design, with twelve treatments and three replications. The substrates formed by the higher levels of cattle manure plus biochar (30%) provided better results of height, diameter and aerial biomass. However, the Dickson Quality Index has not confirmed the quality of seedlings in these treatments. We also observed that the doses of biochar (20 and 30%) when added separately to the Latosol, are not efficient for the growth improvement of the seedlings. Based on the present results, we validate the hypothesis that substrates formed with a mixture of cattle manure and biochar are effective to improve the production of seedlings of M. pubescens.
